More Details :
5pcs 1/4'' Tungsten Carbide Rotary Point Burr Die Grinder Shank Set Dia.8mm
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
They all feature toughened and hardened steel shanks that provide rigidity and strength. This prevents bending and reduces vibrations for an improved tool life.
Tungsten carbide is approximately twice as stiff as steel, with a Young's modulus of approximately 530–700 GPa (77,000 to 102,000 ksi),and is double the density of steel—nearly midway between that of lead and gold. It is comparable with corundum (α-Al2O3) in hardness.
