The versatile 1/4 In. (6.4 mm) diameter carving bit is made of high-grade steel for use on wood, plastic and soft metals. For use with all Dremel high-speed rotary tools, these high-speed cutters work well for detailed material removal in applications like shaping, carving, engraving, hollowing, precision cutting, grooving, slotting, inlaying, making tapered holes or freehand routing. The arrow shape of the carving bit can be used to make flat or tapered side cuts. The accessory tip makes V-bottom slots and grooves or V-cuts when held at 45-degrees.
