Dremel 9911 Tungsten Carbide Cutter, 1/8"

Tungsten Carbide Carving Bits are ideal for shaping, smoothing or removing material from especially hard materials including: hardened steel, stainless steel, cast iron, nonferrous metals, fired ceramics, plastics and hard woods

Tungsten carbide is 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
