dremel bits guide: list of best dremel bits and their uses

Dremel tools are little rotary tools. They fit nicely in your hand and have a little spinning blade or a cutting tool known as Dremel bit at the end. Much like its big brothers, the die grinder and angle grinder, the Dremel tool is an extremely versatile tool. The sheer amount of jobs that it can do is staggering. However, to take advantage of this versatility, you have to find the right accessory or tool bit for your Dremel tool.

Im pretty familiar with the various tool bits that you can get for your Dremel tool, and so I figured that I would share that knowledge with you. But first, let me explain what exactly a Dremel bit is.

A Dremel bit is a tool bit that can change the function of the Dremel rotary tool and allow it to do a variety of different jobs. You just simply attach it to the front of your Dremel rotary tool and you are ready to go.

In this guide, I plan to show you a large selection of the various Dremel tool bits out there. There are quite a few, so I could never cover them all. However, I plan to cover a bunch of the more useful ones so that you can see just how handy a Dremel tool can end up being.

One of the main things that you can use your Dremel tool for is sanding down various surfaces. Whenever you hear the term sanding, your mind immediately jumps to wood sanding, and for good reason. With the right bit, you can definitely use your Dremel tool for sanding and smoothing out wood. However, dont make the mistake of thinking that you are limited to just that, because you arent. With the right sanding disc or band, you can sand materials like fiberglass, clay, plexiglass, and more.

The first kind is known as drums. Basically, they look like little round cylinders. You attach the cylinder to the end of your Dremel tool and then you slip what is called a band over the cylinder. The band has abrasive particles on it and the drum holds the band. The band is what does the work.

The second kind is known as discs. If you have ever used a sander before, then this is going to be a bit more familiar to you. How it works is you have these little discs that you attach to the end of your Dremel tool and you use the disc for precision sanding.

While most people, when they need to cut things like wood or tile, will go for something like an angle grinder or a circular saw, the Dremel tool functions perfectly well as a cutting tool if you know what bits to use. There are plenty of different kinds of cutting bits that you can use. Pretty much all Dremel tool bits that are meant for cutting are shaped like discs. However, that doesnt mean that all cutting discs are built the same way. Some of the cutting discs are made with minimal gaps between the teeth (more number of teeth) for very precise cutting. Others have very large gaps between the teeth, which helps for bulk cutting, where you dont really care too much what the final product looks like.

Much like with the sanding bits, you might be tempted to think that cutting bits for your Dremel tool is only able to be used with wood, but again, you would be mistaken. Regular cutting bits can be used for wood, but if you need to cut things like thin metal, aluminum, or tile, then you can use a fiberglass cutting bit instead.

Dremel tools are perfect for doing etching, engraving, carving, or general decorative work. This is because Dremel tools are extremely small and allow for very precise engraving and decorating. Using etching and engraving bits is easy. You just pick the specific bit that you want and pop it onto the end of your Dremel tool. They come in different patterns, sizes, and styles, so all of the difficulty comes from finding the one that works best for you.

If you needed more proof that the Dremel tool is one of the most versatile power tools out there, how about the fact that in addition to cutting, engraving, sanding, polishing, and everything else that it can do, it can also act like a drill. Thats right, with the right routing or drill bit, your Dremel tool can become a great option for routing wood or drilling into soft material like wood, plastic, or thin metal.

As with all of the other bits that I have talked about so far, there are a wide variety of different routing and drilling bits for you to choose from. So, regardless of what sort of drilling and routing work that, you need to do, you should be able to find the perfect bit to use.

Do you have an old blade or axe that could use a bit of upkeep? Do you have some metal that has a bit of rust that needs to be ground away? If so, then there is no reason why you cant be using your Dremel tool for that. There are a bunch of very useful grinding and sharpening bits that you can pick from.

First off, there grinding wheels. These are generally made from abrasive material such as Aluminum oxide. They are usually in disc shape with a thin cross-section compared to the diameter. The thin grinding wheels can be used for parting-off and cutting while the thicker wheels are good for general purpose. The edge wheels and Paint & Rust Surface Prep wheels are great for grinding off stuck-on rust from metal surfaces.

Secondly, there are grinding or sharpening stones. As you might have guessed, these stones are what you use for sharpening knife blades, ax blades, and much more. These sharpening stones are often made of silicon carbide or aluminum oxide. They are cylindrical in shape and work well for grinding profiles and holes.

In this next part of this article, I want to quickly talk about what the Dremel tool bit is good for each job. Obviously, I cant cover every job, but I can go through a few of the more common and more popular ones.

If you want to use your Dremel tool for cutting wood, then the best option for you is to invest in a carbide cutting wheel. These bits are great at quickly cutting through even the toughest pieces of wood.

For wood carving, you can get hardened high-speed steel bits or carbide bits. The carbide bits are more durable and will last you for a while. Likewise, the carbide is so good at cutting, that it allows you to do both bulk cutting and more precise cutting as well.

If you need to cut something tough like metal or if you just need to work with it, then you are going to need to invest in a Dremel metal cutting wheel tool bit. To be more specific, look for an abrasive cutting wheel that is made out of a material like fiberglass or even better, aluminum oxide. These are great for metalwork. For metal engraving work I recommend carbide bits. They are good for carving soft metals like aluminum, brass, etc. For hard metals like steel, you can use carbide burrs for deburring and chamfering. However keep in mind that while carbide bits are very hard, they are also brittle.

If you need to cut glass, then you need a Dremel tool bit that is made out of the diamond. This is something that is true for basically every power tool. If you need to work with glass, then you need diamond-tipped equipment, it is basically non-negotiable. This is because glass is very hard and brittle.

Again diamond-tipped bit is the best choice. However before you go and buy a diamond-tipped burr, you should know that the selection of tools also depends on the type of stone or rock that you are going to work.

Soft stones like sandstone and soapstone are easy to carve. You can also carve soft marble, but it takes time. If you want to remove a lot of material, then consider using a chisel and hammer to get the rough shape and finish it with Dremel.

Diamond bits are available in different grit sizes from 40 grits (coarse) to 600 grit (fine). The standard 150 grit diamond-tipped bit can work very as an all-purpose Dremel bit for stone, glass and other such hard materials.

7 carbide burr facts | wide range available

Helpful notes: For drilling holes in hard metals you would need to use carbide micro drills or carbide straight shank drills. For cutting slots, routing, profiling, contouring, counter-boring, and reaming you would use a a carbide end mill, carbide slot drill or a carbide router. For cutting and shaping stone or glass you would use a Diamond Burr.

Die grinder bits can be used on a multitude of materials: metals including steel, aluminum and cast iron, all types of wood, acrylics, fibreglass and plastics. Carbide burrs are also perfect for working on softer metals such as gold, platinum and silver as they last a long time with no chipping or breaking.

Yes, the clue is in the title...Ideally carbide burrs are used in Air Tools i.e Die Grinders, Pneumatic rotary tools and high speed engravers. Micro Motors, Pendant Drills, Flexible Shafts, and hobby rotary tools such as a Dremel.

Carbide burrs are widely used for metalwork, tool making, engineering, model engineering, wood carving, jewellery making, welding, chamferring, casting, deburring, grinding, cylinder head porting and sculpting.

Single cut (one flute) carbide burrs have a right handed (Up cut) spiral flute. These tend to be used with stainless steel, hardened steel, copper, cast iron, and ferrous metals and will remove material quickly. Use for heavy stock removal, milling, deburring and cleaning.

Double cut carbide burrs tend to be used on ferrous and non ferrous metals, aluminium, soft steel and also for all non-metal materials such as plastics and wood. They have more cutting edges and will remove material faster. These are the most popular cut and will see you through most applications.

Double cut are sometimes referred to as Diamond Cut or Cross Cut (2 flutes cut across each other) . They will leave a smoother finish than single cut due to producing smaller chips as they cut away the material. Use for medium-light stock removal, deburring, finishing and cleaning.

The shank is the mount of your burr that fits into your rotary tool, die grinder, micro motor etc; so to make it clear, it is the opposite end to the working part of the tool. These are usually found in the following shank sizes:

Use a ball or spherical shaped carbide burr to create concave cuts in your material or to shape and hollow out an area. Small carbide ball burrs from as tiny as 0.5mm in diameter are ideal for intricate carving projects. Many wood carvers, stone carvers and metal engravers use these carbide carving burrs in a hobby drill, micro motor or a high speed handpiece. As we mentioned before, make sure to use a handpiece that runs true i.e with no wobble.

Choose from an end cut cylinder (with a cutting edge on the end) for contour finishing. Cylinder without end cut (flat on the end and no cutting edge) for contour finishing and right angled corners or a round nose or ball nose shape which is a cylinder shaped carbide burr but with a rounded head.

Choose from 60 degree or 90 degree angle countersink burs, sometimes referred to carbide cone burrs. These are ideal for beveling, counter-boring, chamfering and for getting into acute angled areas of your work.

"I love the smaller version and range of points in this carbide burr set. I work on Whitby Jet which is 3-4 on the Moh hardness scale. The material is a natural organic fossil and does have the occasional inclusion of other minerals in it. These can be calcite grains (called spar) or flecks of pyrites both of which are much harder than the Jet. This is where the benefits of the sharpness of the cut and the lovely variety of points in these carbide burrs works well" - Hal Redvers-Jones. The Whitby Jet Heritage Centre.

The speed at which you use your carbide burr in your rotary tool or die grinder will depend on the material you're using it on and the contour being produced, but it's safe to say you do not need to exceed speeds of 35,000 RPM. The table below shows some approximate speeds.

Helpful note: If the burs are chipping easily this could be due to the speed being too slow. However, it's ideal to start the cutting slow, increasing the speed as you go along. High speeds will prevent clogging in the flutes of your burrs.

As with all drill bits and burrs, let the burr do the work and apply only a little pressure otherwise the cutting edges of the flutes will chip away or become smooth too quickly, reducing the life of your burr.

Good quality Carbide Burrs are machine ground from a specially chosen grade of carbide. Due to the extreme hardness of the Tungsten Carbide they can be used on much more demanding jobs than HSS (High Speed Steel).
