Specifications:
Material: Tungsten carbide aluminum
Shank Diameter: 6mm
Cutting Diameter: 10mm
Head Shape: A/D/E/C/L/F
Speed: 6000RPM~40000RPM
Processing Hardness: ≥85HRA

Note:
1, Rotary file in pneumatic or electric tools, the speed is generally 6000-40000RPM, must clamp the tool firmly.
2, Cutting direction should be from right to left uniform movement, not like the use of grinding wheel as reciprocating cutting; be careful not to force too much (the pressure is generally not more than 4 kgf).

Package Includes:
6 x Rotary Burrs
These burrs are made of tungsten carbide aluminum for high hardness, high abrasion resistance
There are total 6 pieces burrs in various shapes that you can use for many purposes
6mm round shank would fit many electric powered or pneumatic powered tools
Could cut cast iron, cast steel, carbon steel, alloy steel, stainless steel, copper, aluminum, marble, jade, bone, etc
