All our tungsten carbide burr cutting tools are manufactured here in the USA. Single cut is a general purpose tool designed for cast iron, steel, some copper and brass and other ferrous materials. It will give good material removal and workpiece finishes. Single Cut: Usually used with stainless steel, hardened steel, copper, cast iron, and ferrous metals and will remove material quickly with a smooth finish. Use for heavy stock removal, milling, deburring and cleaning. Designed for heavy removal of material, milling, deburring, cleaning, and creating long chips. Uses for Carbide Burrs: Carbide burrs are widely used in metalworking, tool making, engineering, model engineering, wood carving, jewelry making, welding, chamferring, casting, deburring, grinding, cylinder head porting and sculpting. Carbide burrs can be used in the aerospace, automotive, dentistry, stone and metalsmith industries. Suggested RPM Speeds: The speed that you use your carbide burr in your rotary tool will depend on the material you're using it on and the shape being produced, but typically you do not need more than 35,000 RPM. If the burrs are chipping easily, this could be due to the speed being too slow. We suggest starting the burr off slow, and increasing the speed as you go along. High speeds will prevent clogging in the flutes of your carbide burrs. As with all drill bits and burrs, let the burr do the work and apply light pressure, otherwise the cutting edges of the flutes will chip away or become smooth too quickly, reducing the life of your carbide burr. Our carbide burrs we manufacture here in the USA 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). Carbide Burs also perform better at higher temperatures than HSS, so you can run them hotter, and for longer. HSS burrs will start to soften at higher temperatures, so carbide is always the best choice for long term performance.
