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

Product Information

These differently shaped burs will get into many a nook and cranny and produce some interesting profiles. Carbide Ball Burrs 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. Since the rotary polishing bits are round in cross-section, they are perfect for polishing holes and curved surfaces. I regularly use the mounted point polishing bits to clean and polish the die profiles.

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. Finally, because of how powerful they are, pneumatic die grinders probably aren’t the best option for jobs that require a lot of precision and a soft touch. Die Grinder Bits Straight die grinders are just regular die grinders. They are completely straight and almost resemble a sort of large screwdriver. Right Angle Die Grinders Ever wondered why it is called die grinder? The die grinder got its name from the original purpose for which it was developed. That is to grind the dies used in tooling. These include metal stamping dies, plastic molds, die-casting dies, forging dies, etc.Today toolmakers use die grinder for deburring, chamfering, polishing, grinding and matching the welded surface, etc. 2. Polishing Metal Use for rounding off edges and making concave cuts. Use the pointed end for cutting in hard-to-reach areas and acutely angled contours. Carbide Inverted Cone Burrs Alright, so to help you understand why this particular tool is useful, why don’t I illustrate some of the scenarios where you can use a die grinder? In this section, I’m going to go through some of the more common uses of a die grinder. 1. Reworking Dies Long shank carbide burrs can also be found, and these are great for detailed carving in hard-to-reach areas of your work. Head Diameter sizes:

One of the more versatile, but often underappreciated tools out there is the die grinder. If you aren’t familiar with these tools, don’t worry because I imagine you aren’t alone in that regard. Even if people have heard of the name, I think that many people don’t actually know quite what these tools do. HSS burrs will start to soften at higher temperatures so die grinder bits made from tungsten carbide are always a better choice for long-term performance. What Are The Advantages of Tungsten 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.

1. Carbide Burrs Can be Used on Many Materials

Sizes refer to the diameters in the cutting head, as well as the shank. This can be stated both in imperial and metric units. Burr diameters range between 1/8 to 1 inch or 3 to 25mm in the cutting head with the most common size being 1/4 inch or 6mm. Shank diameters also differ and range from 1,6 to 16mm, meaning besides die grinders, carbide burrs are also suitable for smaller rotary tools like Dremels and pendant drills. The shanks can also be in standard or extra-long lengths, helpful when working in tight spots. Summing It Up Different cuts of tungsten carbide burs are best suited to certain materials, see the next point below to find out about the different cuts. What Do You Use Carbide Burrs or Die Grinder Bits In? Use inverted cone shaped tungsten carbide burrs for making v-cuts and rear side chamfering. Carbide Pointed Cone & Carbide Round Nose or Ball Nose Burrs Another significant difference is how much variation there is. Dremel tools only come in one version, which is a handheld electric model. As I will go into more depth about, later on, die grinders come in two types, electric and pneumatic. So, if you already have an air compressor set up in your garage, then buying a die grinder makes more sense. There aren’t pneumatic options out there for Dremel rotary tools. Certain types of stone or fossils such as Whitby Jet can also benefit from the use of tungsten carbide burr bits, but these are the exception, and the rule would usually be of its stone, use diamond burrs.
