Dremel Tungsten Carbide Cutter Extra Coarse 1/8 In Shank Model 9904
Description
The Dremel 161040 Tungsten Carbide Cutter (manufacturer #9904) is a high-speed rotary bit for hard materials. Tungsten carbide construction lets this cylinder-point cutter bite into hardened and stainless steel. The cutter also handles cast iron, nonferrous metals, fired ceramics, plastics, and hard woods. Its single-cut right-hand spiral flute clears material quickly during aggressive shaping passes. With a 3/32-inch point diameter, the cutter reaches close detail areas for engraving. A standard 1/8-inch shank fits all Dremel rotary tools and most third-party collets. The cutter carries a maximum speed rating of 30,000 rpm. Extra-coarse grit suits flash removal from castings, plus smoothing and grinding jobs where a slower abrasive point would stall.
