1/8 In. Rectangle-Shaped Tungsten Carbide Cutter For Steel, Stainless Steel, Iron, Ceramics, Plastics And Hard Wood

The Dremel 9901 is a 1/8 inch diameter tungsten carbide cutter designed for precision shaping, smoothing, and material removal on hard surfaces. Built from tungsten carbide, a material nearly as hard as diamond, this cutter delivers exceptional durability and heat resistance that standard steel bits cannot match. It is ideal for both detailed work and aggressive cutting tasks across a wide range of materials.

This rotary tool bit excels on hardened steel, stainless steel, cast iron, non-ferrous metals, fired ceramics, hardwoods, and plastics. Whether you are grinding, shaping, or smoothing tough materials, the carbide construction maintains its sharp edge and integrity even at high speeds.

Features and Benefits
