Engraver nozzles - varieties, purpose, application features. Mini circular saw attachment for Dremel DIY hand sander for Dremel

There are just too many for sale. various tools, which can be used for machining details. An example is an engraver. In many ways, this tool is similar in its principle of operation to a drill or grinder, but is designed to work with workpieces. small size. By purchasing and installing various nozzles for the engraver, you can carry out grinding, milling or engraving, as well as drilling. It is important to choose the most suitable options execution of nozzles, as they are characterized by different performance and scope.

Nozzle Features

Nozzles for a wood drill can be classified according to a fairly large number of different features. There is a wide variety on the market. Almost all equipment for the engraver is characterized by the presence of two structural elements:

The shank is a part of the engraver attachment, due to which it is fixed in the cartridge of the equipment used.
The working part is responsible for the direct removal of the metal layer at the time of processing.

Metal engraving paste is used to significantly increase the efficiency of the processing, especially if the engraver's tool is intended for surface grinding. The description of the nozzles may be distributed by manufacturers, since the cutting edge of some embodiments may have a complex geometry.

Equipment for the engraver can have just a huge amount hallmarks. Burs for a drill and other types of equipment can be classified according to the following criteria:

The type of material being processed.
Appointment of the drill and the applied nozzle of the engraver.
Areas of use.

An example is diamond cutters for an engraver, which can be used to process the end surface and obtain a surface of complex shape.

The use of hard coating can significantly extend the life of the cutting edge, as well as provide higher cutting conditions. A mini drill for a drill is used to obtain deaf or through holes with the smallest diameter. The main classification can be called the one for which technological task the nozzle for the engraver is purchased. Due to the provision of diversity in this indicator, the scope of the engraver is significantly expanding.

By type of material being processed

When choosing the most suitable set, attention is paid to what materials it is intended to work with. The classification of instruments in this case is as follows:

Most of the options are designed to work with wood. An example is the fact that the engraving cutter for wood has become widespread. It can be used to obtain various patterns. If necessary, provides high precision processing.
Use an engraver with appropriate nozzles for working with metal. In this case, in the manufacture of the cutting edge, more wear-resistant and hard alloys are tried on. When choosing a tooling, it is important to pay attention to what kind of alloy will be processed. An example is the ratio of the hardness of aluminum and hardened steel.
Quite often, glass equipment is purchased. Such material is difficult to process. That is why often the cutting part is made of wear-resistant alloys or diamond chips.
There are nozzles for the engraver, which are designed to work with stone. The diamond cutter on stone has become quite widespread. The high hardness of the machined surface determines that special requirements are placed on the cutting edge.

The purpose of the type of material being processed largely determines the cost of equipment. The most affordable offer is considered to be wood cutters, which are very widespread. Also often there are versions designed to work with metals.

By appointment

A tool for engraving on metal or wood can be designed for a wide variety of operations. On this basis, the following options are distinguished:

For engraving work. Very often, some kind of drawing or inscription needs to be applied to the surface. If the work is carried out in a home workshop, then more the right tool can be considered an engraver. There is an engraving cutter for metal or wood, artificial or natural stone, glass and other materials. Diamond burs (cutters) are often sold as a set, since nozzles with different cutting edge geometries may be required to obtain complex patterns and inscriptions.
Tools, the nozzles of which are represented by a combination of a solid metal rod and an abrasive tip. In some cases, it is necessary to bring the quality of the roughness of the recesses or other complex surfaces. In such cases, it is precisely this equipment that is used. Its purpose is to rough and finish the surface, it all depends on the grain size of the abrasive material used.
For grinding and polishing. On sale you can find just a huge range of grinding nozzles engraver. Various materials can be used in their manufacture. An example is a classic abrasive or felt.

When choosing, it should be borne in mind that for engraving and other engraver nozzles designed for surface grinding, there are a variety of pastes. Their use can significantly increase the efficiency of the operation. The selection of the paste is carried out in accordance with what kind of tool is used for processing and what material the part was made of. Before using any paste, you should pay attention to the instructions for use.

Considering the classification, we also pay attention to the fact that there are working nozzles for professional engravers. They are intended for a multifunctional tool that can be used to perform a wide variety of operations. The most common set of such equipment is represented by the following combination:

Cutters that have a different shape and size.
Cones made of abrasive, felt or diamond coating.
Drills that turn a conventional engraving machine into an efficient drill for precision drilling.
Wire nozzles, through which you can clean the surface.
Cutting discs designed to remove part of the product.

If desired, the set can be assembled with a separate purchase of all attachments. However, some versions are extremely rare on sale, which makes it difficult to purchase them separately. An example is cutting discs.

A set of nozzles for an engraver is produced under various brands. As noted earlier, with frequent processing of workpieces by the tool in question, a fairly large set of nozzles is required. The following factors may influence the choice:

What technological tasks will have to be performed. As previously noted, a drill can be used to carry out just a huge number of technological tasks: engraving, surface grinding, cutting, drilling, and others. The choice is made in accordance with what kind of work will be carried out. There are on sale universal sets, represented by a combination of nozzles of various types.
Characteristics, geometric features of the workpiece and the type of material used in the manufacture.
Estimated sizes of blanks. Too small a tool is not convenient to handle larger workpieces. At the same time, it may take much more time to achieve the goals.

A set of cutters and other nozzles can be minimal or include several dozen units. In this case, the choice depends on what budget is allocated for the purchase of equipment and how often the work will be carried out.

When choosing, attention is also paid to the classification according to the purpose of the sets:

Professional level. The high cost of such a proposal is primarily associated with a long service life and exceptional performance. In addition, the cutting part retains its shape for a long period, which ensures the accuracy of processing. It is advisable to choose such equipment only if the relevant work is carried out frequently.
budget proposals. This group can be conditionally divided simply into a huge number of categories. The most affordable tool will be an offer from Chinese manufacturers, but it will not last long and often does not meet the stated characteristics. Some well-known manufacturers are also engaged in the release of instruments of this class, but at the same time withstand quite high level quality. That is why, with rare work, attention should be paid to just such a proposal.

When buying a tool, you can inspect it. There should be no obvious mechanical defects on the surface. In addition, much attention is paid to symmetry, which is quite difficult to check without special equipment.

Making nozzles with your own hands

For some surfaces, it is difficult to find a more suitable nozzle on sale. That is why many are considering the possibility of making them with their own hands. An example is dremel cutters for wood, which are also quite widespread today.

In the home workshop, you can make a cutting disc or grinding head. The primitive cutter is represented by a corrugated cylinder from a conventional lighter. The sanding attachment is made from a wooden drum, to which sandpaper with the required grain size is attached.

Do-it-yourself engraver nozzles are made due to the fact that they can replace completely purchased versions. However, do-it-yourself woodcarving nozzles are very difficult to make. This is due to the fact that the working part of such a tool has a complex geometry, which can only be repeated by a true professional using special equipment.

When making your own equipment, you should pay attention to the features of fastening. A corresponding element from a broken tool can be used as a shank.

An engraver, otherwise called a mini drill, dremel, straight grinder or drill, is a multifunctional tool. With its help, not only apply engraving, but also drill, grind and perform other operations for processing various materials, such as wood, metal, glass, stone. The device is widely used both in everyday life and in various industries, in jewelry, when creating advertising and souvenir products. All the variety of functionality of the equipment is due to the fact that there are various attachments for the engraver.

Nozzles for frequently performed types of work are supplied with the tool. Milling cutters for more specific operations need to be purchased separately. In order to work correctly and productively with a dremel, while achieving high quality parts, you need to know the existing types of equipment, as well as for what work each type is used.

There are a large number of varieties of equipment for working with a mini-drill. A wide range on the market allows you to choose nozzles for wood and many other materials that engraving equipment can work with. Also, individual masters make them on their own.

Structurally nozzles (burs) consist of two parts;

tail, clamped in the tool chuck (diameter from 0.8 to 8 mm);
worker, which processes materials.

Equipment is classified according to two main criteria:

by the type of material from which they are made;
by area of use (purpose).

By type of material being processed

According to the material of the cutter for the engraver, there are the following types.

There are also combined burs, in which the shank is steel, and the working part is carbide. The scope of their application corresponds to the material of the head.

Carbide tooling is of high quality, durable and belongs to a number of expensive consumables for dremels. The shape of the tips determines the features of its application. With the help of such peak burs, it is good to process bone, plastic, to do tracing (indicate the contours of the picture). Diamond tips also differ in quality, even if the kit they are included in belongs to the category of cheap consumables.

On the market you can find a set of burrs, all elements of which marked with any color- it indicates the level of sharpening. Those marked in black are the most productive burs, while the sharpness of green or blue is already worse. Marked yellow nozzles are the best choice when finishing workpieces.

By appointment

You can use an engraver with nozzles not only for engraving, but also for performing other work operations. The division of consumables used in the operation of straight grinders is presented in the table below.

Work in progress	Applicable nozzles
engraving	suitable for the above varieties.
drilling	performed with steel or carbide drills
polishing	circles made of felt, cotton, felt, sandpaper, leather, as well as special devices (holders) that can be wrapped independently (for example, with felt)
grinding	grinding stones (of various shapes and from different materials) and circles (from sandpaper), diamond rings, rubber cylinders
sheet piling	burs with spherical working part
cutting	cutting discs
milling	cutters
surface cleaning (e.g. from rust, scale)	wire (steel), thread, fabric brushes
finishing holes or cavities	diamond cutters
creating grooves	cone burs

Consumables from each group can be used when processing various materials. Wherein tooling for milling used mainly by professionals.

Dremels that have a flexible shaft are equipped with any kind of consumables that fit the diameter of the tool chuck.

An overview of the most popular attachments for woodworking and metalworking

Wood is one of the most frequently processed materials for engraving, along with glass, metal, and stone. Dremels are often used when carving wood, drilling miniature holes in wood, painting on the surface of this material, sanding, and also creating small grooves or tongues. Therefore, popular varieties of nozzles for woodworking are:

cutters for wood;
drill;
circles for cutting;
polishing, grinding wheels and cylinders;
spherical and conical burs;
diamond and hard-alloy nozzles of various shapes;
felt balls.

There are also specific types of wood cutters, but they are used very rarely even by specialists. Purchase consumables to process wood different breeds using straight grinder, recommended set. Thus, everything that may be needed when performing work manipulations will be collected immediately in one case.

Overview of professional attachments for the engraver

A professional tool is a separate (high-quality and expensive) category of equipment that can withstand significant operational loads without negative consequences. Such devices are usually equipped with appropriate consumables.

Professionals do quality work the smallest details blanks. Therefore, they require such a wide variety of consumables when doing work.

Professionals who engrave various materials professionally recommend purchasing sets of nozzles from well-known brands, such as Dremel or Dexter. The significant cost of products of these companies is fully justified by the fact that their products are distinguished by reliability, high quality and durability. The use of burrs for wood, metal and other materials produced by these companies increases the accuracy of workpiece processing.

Often, specialists have several sets of equipment designed to process different materials and perform various operations. Also, the individual elements that make up their composition have their own design features. Usually these sets include:

milling cutters for metal, wood and other materials of various designs;
drill;
felt, diamond, as well as abrasive cutters;
wire brushes for cleaning surfaces;
engraving rods;
cutting discs.

Also in the set comes across a straight edge cutter.

Edge cutter Topfix

Replacement equipment brands "Dremel" and "Dexter" can be used not only by workshop specialists, but also by home craftsmen who want to improve in the art of engraving.

According to professionals, one such tool can last as long as 10 low-quality nozzles of unknown production.

Some engravers recommend products firm "Zubr", lower quality than Dremel or Dexter, but cheaper. The set can include up to 180 consumables of popular varieties. But products from Zubr, in general, belong to the semi-professional and household categories.

Usually, a milling head for an engraver is included with the purchased tool. But with constant use, it wears out over time. Also, cutters may be needed for specific operations - then you need to buy new burs in order to continue working with a dremel.

The ideal option is to purchase products recommended by the engraver manufacturer. In such cases, the warranty from the firms for the operated device is preserved. But it happens that the original consumables cannot be obtained for some reason, or they will be very expensive with a small amount of upcoming work operations. Then you will need to purchase analogues or even use homemade products. In this case, the main selection rules are as follows.

You should focus on a suitable dremel cartridge shanks diameter: most often it is 2.4 or 3.2 mm.
It is necessary to purchase nozzles for metal and other materials for the type of work that is planned to be performed.
To engrave, you can use cheap kits, for example, Chinese or Russian production.
With constant, long-term work with a mini-drill (especially with hard materials), it is recommended to purchase high-quality, professional sets, and for occasional engraving, household ones are enough.

Inexpensive products are suitable during training in various operations with a dremel. Over time, they should be abandoned in favor of better equipment.

Homemade nozzles for the engraver

You can buy attachments for the engraver not only factory-made, but also make them yourself. Workshop specialists and home craftsmen have come up with many options that are suitable for various operations with different materials.

To independently make polishing, grinding, milling, drilling consumables for dremel, as well as cutting devices, use the following materials and parts:

plywood;
sandpaper;
remnants of abrasive wheels of different thicknesses from an angle grinder (grinder);
felt;
felt;
various fabrics and rubber;
steel wire;
a wheel from a cheap lighter;
old burs and drills (they are sharpened);
knives from an electric razor;
hacksaw blades;
metal caps, for example, from beer bottles;
champagne corks;
an ordinary dowel (teeth are made on its cap) and others.

The photos below show some ready-to-use homemade devices to the engraving device of the milling type.

Additionally, with homemade use special (e.g. diamond) pastes. At the same time, specialists achieve the result of finishing processing of workpieces of different densities, comparable in quality to the use of factory analogs of burs.

Homemade engraver attachments are suitable for a variety of jobs. in domestic conditions. They will also save cash through the use of affordable, cheap materials and parts from improvised or broken (unnecessary, old) mechanisms.

A wide variety of different attachments allows you to perform a wide range of tasks with your Dremel. various works with different materials. It is better to select consumables that comply with the recommendations of equipment manufacturers. Professional kits- this is a guarantee of product quality, but they are expensive. To save money, you can make the necessary fixtures yourself. It should only be borne in mind that in this case the warranty service for the mini-drill is lost, and during operation the load on the tool may increase.

In terms of functionality, the use of an engraver is in many ways similar to the work grinder or drills. But there is one important distinguishing feature - it is used to process miniature parts.

Thanks to the use of this device in combination with a set of nozzles for the engraver, it is possible to perform such technological operations as grinding, milling, drilling, engraving, and so on.

The main features of the nozzles

The tool is designed for finishing a fairly large number of various materials. They can process ceramics, wood, glass and plastic products, hard steel.

To work with each of them, different nozzles with different design specifics are used.

Today, specialized companies offer a wide range of various nozzles necessary for carrying out operations with this tool. Their design contains two main components:

working part that performs main function when interacting with the workpiece;
a shank that fixes this element in the equipment chuck.

When choosing this device, they pay attention to certain points: the technological goal that needs to be achieved, and the material being processed, more precisely, its characteristics.

In addition, the equipment of some models of engravers with collet chucks is taken into account. For them, nozzles of only certain brands are suitable. To use such equipment, additionally acquire universal collets.

Among the most popular types of nozzles included in the professional kits are diamond burs. The basis of such equipment is made of tool steel.

At the same time, the working part coated with diamond powder. Thanks to the latter, the device is able to quite successfully cope with the processing of steel, glass, ceramics, natural and artificial stones.

The use of diamond burs is most expedient in the event of a need for fine-tuning a figured hole. They are usually sold immediately. sets of ten to twenty pieces, differing in shape and size.

The operation of burs must be carried out subject to certain rules to help prevent damage to the diamond coating. Typical models are equipped with a shank with a diameter of three millimeters.

Abrasive nozzles

Inexpensive options for this equipment include parts consisting of rubber and abrasive material. They are used to work with metal products and stainless steel objects.

Sets of abrasive nozzles usually include five or six instruments with a different shape of the working part. The shank of such a tool is 2.3 mm.

Some companies are engaged in the production of abrasive nozzles different colors , thanks to which the user can quickly understand a particular category of instrument. For example, red abrasive powders are used to work with metal. They are made from aluminum oxide.

But the tools, painted green, are designed to manipulate glass, ceramics and stone. They are coated with silicon carbide. To ensure the convenience of implementing various technological processes, working part of abrasive nozzles produced in several types of forms.

Abrasive devices allow you to perform the following operations:

Grinding the surface of the part.
Hole boring.
Engraving, etc.

They are used for processing necessary materials at home. Wherein professional craftsmen usually such tools are not used, because they do not have sufficient functional potential.

Polishing and grinding attachments

As already noted, engravers are used to grind objects made from different materials.

Typically, for this kind of work, felt nozzle, which is pre-coated with a special polishing paste acting as an abrasive component.

Polishing discs can be used for both rough and final processing. They are also often used when needed. surface finishing having an irregular shape.

To select the most suitable paste, you must first determine the material properties of the product to be sanded. For processing hard metal surface, for example, it is advisable to use pastes based on polishing powder and paraffin.

And for wood finishing, mixtures made from diamond dust with various fractions of grains. They allow you to very effectively get rid of scratches on glass and wooden surfaces and bring them to a perfectly smooth state. At the same time, the most recommended powders are those containing 5/3 and 3/2 diamond fractions.

Felt nozzles for grinding can be used both when processing wood, metal, glass, and for equipping drills in dental clinics or the simplest hand tools.

Work kits for professionals

Equipment of the professional series is represented by a separate category of nozzles.

Good craftsmen usually have at their disposal sets of tools that differ in design, materials of manufacture, and the shape of the working part.

In most cases, such kits consist of the following components:

Various cutters for the engraver.
Abrasive, diamond and felt nozzles.
Drill, thanks to which the installation can be used as a drill.
Cutting discs.
Wire nozzles used to clean the surface from dirt and corrosion.

All these components of the kit allow the specialist to produce accurate and high quality workmanship even very small details. To do this, of course, quite often it is necessary to change the tools used to select the equipment option that is more suitable in a particular situation.

But the end result is worth it. The presence of a master of a large set is often evidence of his professionalism and experience.

Most popular brands

Today's markets offer a wide range of engraver attachments. Thanks to this, you can choose exactly those tools that will meet the financial possibilities and the needs necessary in a particular case.

Speaking of equipment professional level, among the most popular and sought after brands are " Dexter and Dremel". The products of these companies can be effectively used for processing metal, wood, glass and other materials.

Although these devices differ high cost, however they are quite reliable and durable in use. One nozzle of these brands can last ten times longer than its Chinese counterpart. In addition, these tools have high processing accuracy.

As a budget trademark costs pay attention to the company "Zubr”, offering for a relatively small amount to buy a set that includes up to 180 units of various nozzles with different shapes, sizes and design features. Such sets are equipped with tools for drilling holes, milling, diamond and abrasive nozzles, cutting discs.

As for equipment from Chinese manufacturers, there is a very ambiguous opinion about them. Although they cost several times less than high-quality devices, however, such tools cannot boast of their reliability.

Moreover, the Chinese kits contain significantly fewer components than the branded versions. However, professionals in their field, in principle, will be able to cope with such equipment. True, you will have to change tools often.

Making nozzles with your own hands

To carry out simple engraving work at home, necessary tools can be made from improvised materials.

For example, the simplest cutter is made from a corrugated wheel from a lighter or a dowel on which the working teeth are pre-cut.

To make a grinding nozzle, it will be enough to use a wooden drum equipped with a shank with sandpaper glued to its side surface.

Most of the hand-made nozzles do a good job with the tasks assigned to them. At the same time, their costs are minimal.

Which equipment option to choose depends entirely on from the requirements and capabilities of the master, whether it is a Chinese-made tool, a home-made or a professional device.

An engraver or burr machine is a very necessary and useful thing for those who like to carve wood, stone, metal, and so on. But the engraver will fit not only for carving. It can also be a very good help when assembling or repairing something miniature, in order to cut out of metal or plastic the necessary part that cannot be cut with scissors. Also, they can grind minerals, or just beautiful stones. There are a lot of nozzles for an engraver: saw blades, grinding discs, stones of various grain sizes, brushes (both simple and metal), felt discs, various cutters for wood and glass, as well as, of course, drills.

Buying such an expensive thing as an engraver is only half the battle (however, making it yourself is also not tricky). During the entire time of use, it is also desirable to update and replenish existing stocks of drills, cutters and other nozzles, which are also not cheap. In any case, they (for some reason!) Are more expensive than consumables and nozzles for the same tool of a standard size. But it is not necessary to buy them all in a row - some nozzles can be quite easily made on your own. Of course, such complex tools as a wood cutter, a drill or a diamond gimlet for engraving on glass are unlikely to be made, but, for example, small files for cutting wood and plastic, grinding and felt discs, you can easily do it yourself.

Even without skills. I think that every person is able to cut the correct circle drawn with a compass on a workpiece with scissors. In addition, some consumables can not be found in ordinary stores selling this kind of goods. You have to order and wait a long time when they come, and whether they come at all ... And if they do, it’s not a fact that they will turn out to be of high quality and reliable. The sanding discs I recently received in the mail were so fragile that one of them broke with a little pressure... In general, if you want to do something well, do it yourself! Today we are going to look at several options. self-manufacturing stronger tool.

Saw blades for wood and plastic

You will need:

A metal circle, or piece of sheet metal, no more than a millimeter thick.
Compass and pencil.
Scissors.
Drill and drills.
An emery machine with a cutting disc.
Metal bolt with a nut from a children's designer, or from a prefabricated electrical plug.

First you need to draw a circle on a sheet of metal with a diameter of 3-5 cm. Using a compass and a pencil. I had ready-made metal circles from a chandelier, only with a large hole in the center. In order to fit the hole under a small bolt, we cut out (or take ready-made, if any) two washers so that they cover the hole on the future saw blade. We make a hole for the bolt in the center of each washer, crimp the disk hole on both sides with washers, align it in the center, and tighten it with a bolt and nut.

Next, you need to cut the teeth of the disc.

We make oblique cuts along the entire edge of the disk, 3-4 mm deep, and in 2 mm increments. You can use.

We do the disk for cutting plastic in the same way, repeating the above procedures, with the exception of sharpening the teeth. Here, the cuts should be made at a right angle, two mm deep, and also a step of two mm.

The teeth should be short and wide. This disc can cut plastics of different densities, as well as plexiglass and textolites.

Sanding and felt discs

You will need:

A thin grinding disc (you can use it, or even a chip, but not thicker than a millimeter).
A piece of felt, 7-10 mm thick (from felt boots - just right).
Compass and pencil
Metal scissors.
Emery machine.
Thin bolt with nut.

Here, too, the manufacture is not much different from the first two options. We also draw a circle of 3-5 cm with a compass.

Only it is probably better to cut the felt with a sharp knife, since it is thick enough, and I crushed all my fingers with scissors. And it is better to cut the grinding wheel either with scissors for metal, or on an emery machine with the same cutting wheel. Next, we make holes in the centers of the circles, and tighten them on both sides with bolts and nuts.

Some time ago I received a welcome gift - an engraver. Dremel 4000. The box proudly flaunted the inscription "65 nozzles." In fact, about 20 of them turned out to be discs for cutting plastic, so the variety turned out to be not at all what it might seem. Given the completely inhumane pricing policy of this manufacturer and its Russian dealers, I had to surf the Internet. Native nozzles, taking into account the cost of delivery, were catching up with the option “go to Leroy and buy”, besides, the assortment was frustrating. So I had to look towards China. There were a lot of interesting things there.

drilling

The kit included a 3.2 mm collet (and another one that I never used, because there is not a single nozzle in the kit for it). And a drill. The same 3.2 mm. But i.e. we kind of have a tool for fine work and a 3.2 mm drill bit is included. It is a pity that not the eight on concrete.

Cam chuck 4486:

Drills 628 can be inserted into it:

Or use a 3.2mm collet wood drill set:

The cartridge does not have much good design. As far as I understand, the drill is clamped pointwise, the area of the contact spot is small, the revolutions are high, there is a “bounce” of the drill. In addition, there are a lot of reviews on the manufacturer’s website in the style of “Out of curiosity, I completely screwed the cartridge without a drill, and it no longer wants to spin back.”

What do the Chinese offer?

For example, here are the sets:

Visually, the bounce is imperceptible, brass drills remarkably. How many thousands of holes in PCB can be made by one drill before wear - I don’t know, I haven’t tried it. But if you need to make several (dozens) different small holes - a great option.

I ordered on ebay from seller sz_butterfly - he always has lots with a fixed price and regularly holds auctions with a low starting price (and not 15 times the shipping cost). The plastic box-stand was included.

Engraving

What is regular in stores?

Cutters. A bunch of cutters of various sizes and (sort of) purposes. A number of diamond-coated tips. You can open the catalog or the manufacturer's website and look there.

Everything is great, if not for one But- price. For example, such a wonderful nozzle Dremel 7105 (4.4 mm, shank 2.4 mm - the very second collet in the set) costs only 800 rubles for 2 pieces.

What do the Chinese offer?

To begin with, I ordered a set of a variety of diamond-coated drill bits. Just to understand what I need. 180 rubles with delivery:

It turned out to be a great thing. you can draw thin (and not only) lines on metal and glass. Probably plastic too. Something like this:

IMPORTANT!!! When working, be sure to use respiratory protection. I used an ordinary gauze bandage and constantly wiped the product with a wet rag. During operation, quite a lot of well, very fine dust is formed. I doubt that the lungs will be delighted with such a gift.

In my work, I really liked the spherical shape of the nozzle, because it is easiest for her to maintain good work accuracy. So I looked for these Diamond Round Ball Burr Bit Sets:

Or these (300 rubles, free shipping):

Haven't ordered yet. I don't know why I'm dumb.

Literally a month ago, the choice was just that - either you buy native Dremel consumables for 500-1000 rubles a piece, or you order from the Chinese. And 2-3 weeks ago in Leroy (I have one near my office, we regularly go there to look for something tasty) there were also budget consumables for the engraver (for example, mini-sets of diamond drills). So the meaning of waiting for delivery has fallen somewhat.

Offtopic: In addition, canvases appeared there just as suddenly for what the English-speaking Internet calls the oscillating tool, and in our country it is called anything, up to an electric broom

I hope this post will help someone try to do something with their own hands. This is an interesting process.

Offtopic 2: I also faced the problem of finding metal for work. I needed brass. In Moscow, a lot of factories are ready to sell wonderful strips or sheets of brass. From 5000 rubles. Preferably a legal entity. from 10 am to 5 pm. As a result, on the second attempt, I bought what I needed at the non-ferrous metal collection point.
