5pcs Rotary Point Burr Set Die Grinder Bit with 12 mm Shank and 6 mm, Carving Tool Tungsten Carbide Steel

Product Information

Carbide Rotary Burrs, often referred to as rotary files or die grinder bits are used for cutting, shaping, and grinding, and for the removal of sharp edges, burrs and excess material (deburring). Different uses mean the bits come with either a single or double-cutting profile. Single-cut burrs have a single cutting profile or ‘flute’ that runs from the top to the end in a spiral. This is ideal for:

Double-cut burrs for use on non-ferrous materials and plastics tend to have wide chip space and are often referred to as Aluminum cut. Good for rounded edges and surface finishing in difficult-to-reach areas or tight and narrow angles and contours. The round nose or ball nose cone is often referred to as a taper shape. Cylinder Burrs. Round Nose/Ball nose/End Cut In this guide, I want to tell you everything that you could possibly need to know about this handy, versatile little tool. With a die grinder and the right attachment on the end, you can polish, sand, cut, grind, or hone various materials. Obviously, this makes the die grinder useful in a lot of different circumstances, as I will show you later on in the guide. Likewise, I will also explain how the die grinder, like many other handheld tools, is separated into two different kinds based on their power source. Die Grinder Uses

3. The Various Shapes of Carbide Burrs and How To Use Them

These aren’t the ordinary bits that you’d use in drills and impact drivers. They’re made of tungsten carbide, an alloy of tungsten and carbon and exhibit exceptional properties. The alloy is up to three times as hard as steel and has the highest compressive strength of any known metal. In such situations, a right angle die grinder is very handy. It can go in difficult to reach places. See the illustration below. However, there are some downsides to pneumatic die grinders. For starters, the fact that you have to lug around an air compressor and all that comes with it (hoses, tank, etc.) when using the tool makes it very cumbersome to use, especially if you are in a tight space. Likewise, if you don’t already own an air compressor, then getting one that is also compatible with your tool can be both expensive and a hassle.

Carbide burrs, more commonly called die grinder bits, are the attachments used in rotary tools. They’re ideally used for smoothing, grinding, shaping, carving and deburring excess materials in a variety of workpieces. They come in different cutting profiles and shapes to produce different types of cuts. And you can find them in varying sizes. What Are They Made of? Double-cut options have two intersecting sets of flutes. This allows for much smoother surfaces and cleaner finishes in both ferrous and non-ferrous metals, but is particularly good in softer metals like aluminium and mild steel, in addition to wood and plastics. Use double-cut bits in: It is additionally highly resistant to deformation, holds its own against high heat, has exceptional impact and abrasion resistance and is second only to diamonds as the hardest material there is. Tooling them also requires some serious CNC machining considering how hard they are.

4. What Speed or RPM should you use your Carbide Burrs?

Weld Spots: If you do metalworking, then you know how annoying welds can be. A die grinder can easily remove the excess welds for smoother, cleaner looking metalwork. This is definitely a must-have tool if you do a lot of welding or metalwork of any kind. Here is an example to illustrate. In figure.1, you can see that it is impossible to grind the hole with a straight grinder. 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 slowly, increasing the speed as you go along. Higher speeds will prevent clogging in the flutes of your burrs.

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

Bits attached to the end of die grinders and other rotary tools are used across a range of varying professions and fields. Most often this means anyone working with metal and wood. They are basic necessities for metalworkers, welders, smash repairers, tool makers, plumbers, and mechanics, as well as woodworkers, carpenters, joiners and construction workers.

These factors include the types of cut, the size, and the techniques.

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 rotary handpiece that runs true. i.e with no wobble. Similar to double cut are Diamond Cut carbide burrs which have multiple cutting faces, often found on router end mills. When it comes to tungsten carbide burrs, there's a wide range of sizes to align with different areas or applications. The project you're about to work on determines the specific size of burr you'll choose. In most cases, small burrs go with small projects, and larger burrs go with larger projects. Many die grinders can be equipped with a blade sharpening attachment; these allow you to sharpen a wide variety of blades. You can use them for knives, hatchets, axes, and other any kind of blade that you can think of. They are great for those who don’t own a proper grindstone, but who still want to keep their blades nice and sharp. Is A Dremel A Die Grinder?

Generally, a metal burr is manufactured from either high strength steel (HSS) or Tungsten Carbide. When working with metals only, tungsten carbide burrs are mostly preferable. This is due to their durability in handling several demanding jobs without wear or tear. The HSS burrs, on the other hand, have a reduced tolerance for heat. As a result, high temperature and pressure tend to soften the HSS tool. Compared to HSS, tungsten carbide burrs can last longer. Besides the differences in use and the materials, they work best in single and double-cut options and also are distinguished by how they operate. The first produces larger chips, so getting the finish you want may take longer. Additionally, double-cut types are easier to control with the finer cutting profiles and are the ideal type for beginners. Shapes and Sizes Before the arrival of high precision machines such as CNC milling, EDM Spark Erosion, and EDM Wirecut it was common for the die makers to grind and match the profiles of the mating parts manually. As you know, it is tough to remove material from hardened tool steel with a conventional hand tool such as a file. The die grinder is the best tool for the job since they are small and is to maneuver.
