Type T Rotary Bits: Carbide rotary files can be used to process cast iron, cast steel, carbon steel, alloy steel, stainless steel, hardened steel, copper and aluminum. APPLICATIONS: Work well for detailed material removal in applications like shaping, carving, engraving hollowing, precision cutting, grooving, slotting, inlaying, etching, making tapered holes or freehand routing. Extremely Versatile Cutter: The Disc shape of the Carving bit can be used to make channel cuts while the accessory tip allows for side cuts. Our versatile and simple-to-use Carving bits make it easy to express your creativity. Notice: Mainly used on electric or pneumatic tools, the speed is generally 6000-50000 rpm. When in use, the tool holder needs to be clamped positively, and the cutting method should be smoothly moved to avoid reciprocating cutting. To prevent the chips from splashing during work, please use protective glasses.
