Made of high quality tungsten steel, strong and sturdy Shank diameter: 6mm; design: conical shape with round nose, with cut end Easy to use: convenient, safe and reliable control Two types of end for choice: single slot and double slot, single slot suitable for hard materials such as iron, steel and copper; the double slot is suitable for soft materials such as wood, aluminum and plastic Package contents: 1 rotary file Size: Double slot, 16x25mm Features: Product use: Tungsten Carbide Burs are widely used in industrial sectors such as machinery, aviation, automotive, shipbuilding, chemical engineering, and process engraving. Instructions for use Carbide rotary milling cutter is mainly used in power tools or pneumatic tools (can also be installed on machine tools), and the driving speed is usually 6000-50,000 rpm. The difference between double cutter and single cutter. The double cutter is more suitable for low density materials. For example, used on wood, plastic, aluminum and other materials. The texture of the single end mill determines that it is not suitable for processing softer materials such as iron, copper, and steel.
