Dremel’s highly-durable tungsten carbide carving bits can be used for more aggressive applications to shape, smooth, or grind hard materials such as metals, hardened steel, fire ceramics, cast iron, plastics, and hardwoods. The versatile 1/8 In. (3.2 mm) diameter carving bit is made of tungsten carbide. For use with all Dremel high-speed rotary tools, the accessories work well for projects like metal or glass engraving, stone carving, or removing flash from castings. The small taper shape of the carving bit can be used to make cuts in narrow and hard to reach places. Also makes flat or tapered side cuts while the tip makes V-bottom slots and grooves.
