Features: For electric or pneumatic tool drive (can also be used in machine tool)The speed of the electric or pneumatic tools usually is 6000-50000 revolutions per minute,Suitable for deburring and polishing cast iron,cutting,engraving carving,cast steel,carbon steel,alloy steel,stainless steel and other materials Machining hardness reach HRC70,For the most work,rotary burr set it can replace Petiole small wheel.And their working life is 10 times longer than normal HSS Burr, 200 times longer than Petiole small wheel. Double-cut head：Double-cut style has rows of cutting teeth cut in two intersecting directions for fast material removal and a rougher finish The Solid Carbide Rotary Burr Set contains 20pcs rotary burrs. They all feature toughened and hardened steel shanks that provide rigidity and strength. This prevents bending and reduces vibrations for an improved tool life. Specification: Material: Tungsten Carbide Groove:Double Cut Solid Cutting edge diameter: 3mm（10pcs） & 6mm（10pcs） Shank diameter: 3mm Total length: 10pcs of 3*3mm：40mm 10pcs of 3*6mm：42-50mm Packge Included: 20pcs Carbide Rotary Tool Features & Benefits -Double Cut -First choice for general machining -Improves ease of control -Increases metal removal rate -Breaks swarf into small manageable pieces -Aluminium Cut -First choice for non ferrous materials and plastics -High helix and large flute volume for rapid metal removal Brazing: Special brazing elements provide excellent braze strength Excellent impact strength able to withstand high forces Able to withstand higher temperatures without failing Ball Nose Geometry Skip flute grinding Increased strength at the centre Reduced chance of swarf congestion and chipping Improved cutting action closer to the centre
