Package List: 1 x Rotary File Note: 1. When the cemented carbide rotary file is used on pneumatic or electric tools, the speed is generally 6000‑40000rpm, and the tool must be clamped.2. The cutting direction should move evenly from right to left, and reciprocating cutting cannot be performed like using a grinding wheel; be careful not to use excessive force(the pressure generally does not exceed 4kg).
