Rotary rasp bits are cutting and shaping tools designed for use with power drills or rotary tools. Made from hardened steel, they feature coarse, rasp-like surfaces ideal for rapid material removal. These bits are commonly used in woodworking, metalworking, and plastic shaping tasks. They come in various shapes—such as cylindrical, conical, and spherical—to accommodate different cutting and carving needs. Rotary rasps are ideal for rough shaping, deburring, hollowing, and surface texturing, especially on soft materials like wood, plastic, rubber, and some metals
