The only substance harder than tungsten carbide is diamond. Dremel Tungsten Carbide Carving Bits are ideal for shaping, smoothing or removing material from especially hard substances, like cast iron, nonferrous metals, and hard woods. The 1/8-inch Tungsten Carbide Carving Bit can be used in virtually any Dremel rotary tool.
Shapes, smooths or grinds especially hard materials including: hardened steel, stainless steel, cast iron, nonferrous metals, fired ceramics, plastics and hard woods
A high-speed bit made of tungsten carbide, the hardest material next to diamonds
Use higher speeds for hard woods, slower speeds for metals and very slow speeds for plastics
Use the sides of the bit (rather than the tip) for effective cutting
