Specification Brand : Benchmark Abrasives BulletPoint1 : Benchmark Abrasives SM-3 cone burrs are great for narrow contours, surface machining, and getting at rounded edge and surface processing in small places. Due to the extreme hardness of this tungsten carbide, it can be used on much more demanding jobs than HSS (High-Speed Steel). BulletPoint2 : These carbide burrs are made of tungsten carbide burr die grinder bits and will start to soften at higher temperatures, so carbide is always the best choice for long-term performance. BulletPoint3 : Double-cut or Crosscut carbide burrs are used on ferrous and non-ferrous metals, soft steel, and non-metal materials such as stone, plastics, hardwood, and ceramic. BulletPoint4 : Efficient carbide burrs are used in various industries like automotive, transportation, woodworking, shipbuilding, construction, welding, foundries, fabrication, etc. BulletPoint5 : All our abrasive products are made with quality materials and exceed ANSI and EU European Standards. We trust in delivering high-quality products to the end-user. Customer satisfaction is the lifeline of our brand.

Tungsten Carbide burrs can be used on most hard materials: metals including steel, aluminum and cast iron, all types of stone, ceramic, porcelain, hard wood, acrylics, fiberglass and reinforced plastics. Ideally carbide burrs are used in Air Tools i.e Die Grinders, Pneumatic rotary tools and high speed engravers. Carbide burrs commonly come in three cuts; single cut, double cut & diamond cut; we offer DOUBLE CUT. Double cut or cross cut carbide burrs tend to be used on ferrous and non ferrous metals, aluminum, soft steel and also for all non-metal materials such as stone, plastics, hard wood and ceramic. Double cut or cross cut (2 flutes cut across each other) will leave a slightly smoother finish than single cut due to producing smaller chips as they cut away the material. Use for medium stock removal, deburring, finishing and cleaning. A double cut carbide burr is the most popular cut and will see you through most applications. Making a decision on what shape to use will depend on the profile or cut you are looking to achieve. These different shaped burs will get into many a nook and cranny and produce some interesting profiles. The shape if the burr is in the product name i.e. SD, SC SE. POINTED CONE SHAPE (SM) - Good for rounded edges and surface finishing in difficult to reach areas or tight and narrow angles and contours. The speed at which you use your carbide bur in your rotary tool 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. If the burs are chipping easily this could be due to the speed being too slow. However, it's ideal to start the bur off slow, increasing the speed as you go along. High speeds will prevent clogging in the flutes of your burs. ProductSiteLaunchDate : 2016-06-23T07:00:00.000Z Size : 6mm x 6mm SupplierDeclaredDgHzRegulation : not_applicable UnspscCode : 31191600
