Feature: 1. CEMENTED CARBIDE: Made of heat treated integral YG8 cemented carbide, with high hardness and good durability. 2. DOUBLE FLUTE DESIGN: Cylindrical rotary file with double flutes design, with fast chip removal and high grinding efficiency. 3. EASY OPERATION: The rotary file is often installed and used on electric tools, easy to operate, reliable and labor saving. 4. HIGH ACCURACY: With high processing quality and smoothness, and can be processed into various high accuracy mold cavities. 5. WIDE APPLICATION: Can be used for metal products, wood carving, jewelry manufacturing, chamfering, deburring and grinding, etc. Specification: Item Type: Grinding Bit Product Material: YG8 Alloy Product Model: AX1225 Slot Type: Double Slot Tool Shape: Cylindrical Shank Handle Diameter: Approx. 6mm / 0.24in Tool Diameter: Approx. 12mm / 0.47in Blade Length: Approx. 25mm / 1in Application: Widely used in metal products, tool manufacturing, engineering, model engineering, wood carving, jewelry manufacturing, welding, chamfering, casting, deburring, grinding, cylinder head transplantation and carving . Package List: 1 x Grinding Bit Note: 1. When the cemented carbide rotary file is used on pneumatic or electric tools, the speed is generally 6000‑40000rpm/min, and the tool must be clamped.2. The cutting direction should move evenly from right to left, not reciprocating cutting like using a grinding wheel; be careful not to use excessive force (the pressure generally does not exceed 4 kg).
