Safe Storage: This rotate burr set is packed with storage box for safe storage and protection, and long lifeSpecification:Item Type: Double Cut Rotate BurrsMaterial: YG8 AlloySlot Type: Double SlotShank Diameter: Approx. 6mm / 0.24inUses: Widely used for metalwork, tool making, engineering, model engineering, wood carving, jewelry making, welding, chamfering, casting, deburring, grinding, cylinder head transplanting and engraving Package List:8 x Rotate Burr Set1 x Storage Box Note:1. When the carbide rotate 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 cannot be used for reciprocating cutting like a grinding wheel, be careful not to use excessive force (the pressure generally does not exceed 4 kg).
