Grinding nozzles for the graver with their own hands

Nozzles for the graver

On sale there is just a huge number of different tools that can be used for machining parts. An example is the engraver.

In many respects this tool on its principle of operation is similar to a drill or grinder, but is designed to work with workpieces of small size. By acquiring and installing a variety of engraver attachments you can grind, mill or engrave, and drill.

It is important to choose the most suitable variants of nozzles, because they are characterized by different performance and area of application.

New angle grinder function. New DIY tool.

Features of nozzles

Nozzles for wood drilling machines can be classified by a large number of different features. There is a great variety on the market. Virtually all engraver tooling is characterized by the presence of two structural elements:

  • Tailpiece. is the part of the bit for the engraver, due to which it is attached to the chuck of the used equipment.
  • The working part is responsible for the direct removal of the metal layer at the time of processing.

Paste for metal engraving is used to greatly enhance the efficiency of ongoing processing, especially if the tool for the engraver is designed to grind surfaces. The description of nozzles can be distributed by manufacturers, because cutting edge of some versions can have complex geometry.

Types of Engraver Accessories

The accessories for the carver can have just a huge number of distinctive signs. Drill bits and other types of accessories can be classified according to the following criteria:

Budget Consumables for the Engraver

Some time ago I received a much desired gift. an engraver. Dremel 4000. On the box it says “65 bits” proudly. In fact, 20 out of them turned out to be plastic cutting discs, so the variety was not what it seemed. Given the totally inhumane pricing policy of this manufacturer and its Russian dealers, had to get on the Internet. The native tools, taking into account shipping costs, caught up with the option to “go to leroy and buy”, in addition, the range was upsetting. So I had to look in the direction of China. There were many interesting items.

Inspired by Meklon’s post, I decided to try to share with the hubra-community the tricks I found. Some of them I have already tried, some are waiting their turn. I thought for a long time whether to link to specific items on ebay. On the one hand, observed on the hubra allergy to such links. On the other hand. the links are not referral, I’m not a seller, and a post with a description of the nozzles, their photos, but no links “where to buy” seems flawed. Kind of like “I know where the tastiest real sausage is sold, but I won’t tell”.

Drilling

The kit came with a collet 3.2 mm (and another, which I never used, because it has no no nozzles). And the drill bit. The same 3.2mm. But t.е. We kind of have a tool for fine work and a 3.2 mm drill bit in the kit. I wish I had an eight on concrete.

What’s standard in the stores?

Or use a set of wood drill bits for the 3.2mm collet:

The chuck doesn’t have a particularly good design. As far as I understand the drill bit is clamped pointwise, the contact area is small, the rpm is high, you can observe the “rattle” of the drill bit. over, on the site of the manufacturer are a lot of reviews in the style of “I was curious and completely screwed the chuck without a drill, and it does not want to unscrew anymore”.

What do the Chinese offer?

Visually the rattle is not noticeable, the brass drills great. I don’t know how many thousands of holes in textolite one drill can make before it wears out, I haven’t tried it. But if you need to make a few (dozens) different small holes, a great option.

I ordered from ebay seller sz_butterfly. he constantly has fixed-price lots, and regularly has auctions with a low starting price (and not 15 times the shipping cost). Plastic box-stand included in the kit.

What’s available in-store?

Cutters. A bunch of cutters of different sizes and (kind of) applications. Some number of diamond-tipped nozzles. You can open the catalog or the manufacturer’s website and look there.

Everything is great, if it were not for one thing. for 2 grand.

And what do the Chinese have to offer??

To get started, I ordered a set of all sorts of diamond-powdered drills. Just to see what I need. 180 with shipping:

This turned out to be great stuff. can draw thin (and not only) mowing line on metal and glass. For sure on plastic, too. Something like this:

IMPORTANT. Always use respiratory protection when working. I used a simple gauze bandage and constantly wiped the piece with a wet rag. It produces quite a lot of very fine dust. I doubt that the lungs will be happy with such a gift.

I really like the spherical shape of the spray head, because it’s easiest to maintain good accuracy at work. So I got myself these Diamond Round Ball Burr Bit Sets:

Just a month ago, the choice was just that. you either buy native dremel consumables for 500-1000 a piece, or order from the Chinese. And about 2-3 weeks ago in Leroy (I have one near my office, and we regularly go there to look for some tasty things) some inexpensive tools for the carver (such as mini sets of diamond drill bits) appeared. So the point in waiting for delivery is somewhat dropped.

Offtopic: In addition, there are also suddenly appeared and cloths for what the English-speaking Internet calls oscillating tool, and we have it called anything, up to the electric tool

I hope this post helps someone try to make something with their own hands. This is an interesting process.

Offtopic 2: I also had a problem finding metal for work. Needed brass. lots of factories are willing to sell wonderful strips or sheets of brass. From 5,000. It is desirable to legal person. From 10 to 17 hours. As a result, at the second attempt I bought what I needed from a non-ferrous metal recycling center.

Nozzles for the graver and the drill with their own hands

Once again, I return to a question which I have already touched upon more than once in my posts on the site. It is about the nozzles for the engraver and the drill. This topic is probably endless, because in addition to a wide variety of accessories that come with the engraver and drilling machines, or that can be purchased separately in a tool store, home crafters make them with their own hands. And here everyone tends to make what is most necessary to perform those or other works. By the way, of those sets, that were included in my two machines, numbering dozens of nozzles, I use mostly from five to six, and the rest are just lying around “dead weight”, but in order to be at hand and not get lost, made such, as on the top photo, a simple self-made three-tier stand made of wood. Maybe they’ll be useful someday, but now I mostly use different homemade grinding attachments, “sharpened” for those tasks, which I solve with woodworking machines (Profile B-03) and engravers (Caliber and Hammerflex 113-003). Why the homemade ones?? Because I have not encountered on sale good sanding accessories, allowing high-quality performance with a drill and engraver to process the concave surfaces and recesses of wooden workpieces. Yes, there are many different cutters that can quickly remove a layer of wood on these surfaces, but there is almost nothing to sand them with. Commercially available tips. Sanding drums with replaceable cylinders of sandpaper, scrapers and sanding discs are inconvenient, for example, when sanding the recess of the workpiece for a wooden spoon. And sanding with sandpaper by hand is too laborious and tedious process. Here you need a nozzle that is either spherical or oval in shape. over, this bit should have the possibility to quickly and consecutively replace sandpaper with coarse grit by another one with a finer grit. over, it is desirable that this nozzle is easy to make and not expensive. After experimenting with a variety of homemade bits for engravers and drills, I came up with the following option, which, in my opinion, is most suitable for the above tasks. Homemade wooden bases for such tools are easy to make.

What are the bits for an engraver?

The working nozzles, or tools used for engraving, are available on today’s market in great variety. There are two basic elements in their construction:

  • a shank, by means of which the tool is fixed in the chuck of the used equipment;
  • the working part, which performs the main functions, interacting with the material to be treated.

The working part of these nozzles is designed for processing metal surfaces

The choice of work bits for an engraver is influenced by the following factors: the characteristics of the material to be worked and the list of technological tasks that need to be performed. Those of home masters and professionals who work with engraving machine on a regular basis, try to buy immediately a set of nozzles for the engraver, which includes tools of various sizes and purpose. Depending on the needs and financial capabilities of a particular master of engraving it can be a more modest set, which includes a few dozens of necessary tools, or a professional set, which includes attachments for performing various works on metal, wood and other materials.

Types and applications of engraver bits

Engraver, or boron machine. a very necessary and useful thing for those who like to do carving on wood, stone, metal and so on. But an engraver is not only good for engraving. It can also be very helpful when assembling or repairing something miniature to cut out of metal or plastic the right part that can’t be cut out with scissors. Also, you can grind minerals with it, or just beautiful stones. There is a huge set of attachments for graver: circular saw blades, grinding discs, stones of different grits, brushes (both simple and metal), felt disks, different cutters for wood and glass, as well as, of course, drills.

Buy such an expensive thing like an engraver. this is only half the battle (however, to make it yourself, too, is not a cunning matter). Throughout the time of use, it is desirable to refresh and replenish existing stocks of drills, cutters and other nozzles, which are also not cheap. In any case, they are (for some reason) not cheap!) are more expensive than consumables and bits for the same tool of standard size. But you don’t have to buy them all. some nozzles can be pretty easy to make yourself. Of course, such complex tools as a wood cutter, drill or diamond drill for engraving on glass, you can hardly make, but, for example, small saws for cutting wood and plastics, sanding and felt disks, you can easily make with your own hands.

Even if you have no skills. I think everyone is able to cut a right circle with scissors, drawn with a compass on the workpiece. In addition, some of the materials are not found in conventional stores that sell this kind of goods. We have to order and wait a long time for them to arrive, and if they do arrive at all And if they do, it is not guaranteed that they are of high quality and reliability. The other day the grinding disks I received in the mail were so fragile, one of them broke at a light pressure So, if you want something done well, do it yourself! Here’s a look at a few options for making a stronger tool yourself today.

Makeshift Attachments for Engraver with Your Hands

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

Accessories for common types of work are included with the tool. Cutters for more specific operations need to be bought separately. In order to work properly and productively with the dremel, achieving at the same time a high quality of parts processing, it is necessary to know the existing varieties of equipment, as well as for what works use each type.

Saws for wood and plastic

To begin with, a circle 3-5 cm in diameter has to be drawn on a sheet of metal. Using a compass and pencil. I had ready-made metal circles from a chandelier, only with a large hole in the center. To make the hole fit the little bolt, cut (or take ready-made, if available) two washers to cover the hole on the future saw blade. Make a hole in the center of each washer under the bolt, crimp the washers hole disk on both sides, align in the center, and tighten the bolt with the nut.

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

A plastic cutting wheel, do the same, repeating the above steps, except for the teeth are sharpened. Here the notches should be done at right angles, two mm deep, and with the same two mm pitch.

The teeth should be short and wide. This wheel can be used to cut plastics of different density, as well as plexiglass and textolite.

Grinding nozzles for the engraver with their own hands

This guide will be dedicated to making a polishing wheel for mini drills, drills, and simply speaking, for dremel.

After rummaging around in markets and construction stores, I couldn’t find a separate polishing wheel on sale. I’ve seen expensive kits that didn’t ignite much enthusiasm in me. After experimenting a little with thick cloth, came to the ingenious conclusion that instead I need to use nothing but felt. Having made the lists ;), I went to the market to buy.

  • A piece of felt (read more below)
  • Glue (I used PVA, t.к. super glue soaks into the material)
  • Scissors or a blade (optional)
  • A compassesil (if you wish)
  • A plastic lid for ordinary jars (read more below)
  • Dremel with a special nozzle (a small drill, which is screwed into the nozzle for fixing)
  • Straight hands
  • A lighter (for scorching the protruding lint)

The materials required for the polishing nozzle

Here we go. Taking a piece of purchased, or found at my grandmother’s closet, felt. On this aspect I want to make a small pause. There are different kinds of felt on the market. I took, as you can see in the photo, a simple cheap felt 1.3 cm thick. It becomes 1 cm under pressure. You could also use a felt similar to that used on the wheels in my kit, but it was more expensive and, it seemed to me, under pressure could be thinner than 0.8 cm, which would scratch the surface. Because my drill is exactly 0.8 cm. So here we need to be careful. So, the choice of felt is taken care of. Now let’s get down to business. On a piece of cloth, which we hold in our hands, we draw a circle of necessary diameter with a proofreader, or just visually. Here I wouldn’t advise trying too hard, t.к. The dremel may overheat if the circle is too big. I personally have done

An untrimmed piece of felt of the desired diameter

Then we take a plastic lid and draw a circle of the same diameter on it with a compass, as on the felt. Actually, instead of a cover, you can use any other hard material. The function of this plastic will be to hold the fabric in a round, clear shape, because without it, the felt will rozlazatsya at high speeds. I tried to use cardboard instead of plastic, but it is not strong and starts to tear.

Circle of felt, using cardboard

In general, your imagination works here, you can use everything from a binder and ending with the bottom of your favorite yogurt pots. After you cut two circles with scissors and a blade we glue them together, about as you see in the photo.
