Uxcell 3mm Shank 4mm Cutting Dia Double Cut Cylinder Tungsten Carbide Rotary Files

Uxcell 3mm Shank 4mm Cutting Dia Double Cut Cylinder Tungsten Carbide Rotary Files Widely used for metalwork tool making model engineering wood carving welding chamfering casting deburring grinding sculpting. Fit most rotary tools with three jaw chuck for accurate centering. Can replace small grinding wheels. Made of carbide (tungsten steel) rotary files features wear resistance good toughness heat resistance higher hardness but is more brittle. Carbide can run at higher speed than high-speed steel. Carbide material with good milling and cutting performance ensures high work efficiency. Double Cut Design: The groove lines are crossed. Double groove rotary files are more suitable for the object density is relatively low such as wood plastic aluminum. Tips: Requirement rotating speed is: 4000-50000rpm. Always ensure the shank is well inserted into your collet and clamped down tightly.
