3/32 In. X 1-1/2 In. L Tungsten Carbide Cutter 1 Pk

The Dremel 9904 is a tungsten carbide cutter designed for high-speed rotary tools. Tungsten carbide is one of the hardest materials available, second only to diamond, making it ideal for shaping, smoothing, and removing material from exceptionally hard surfaces. This cutter excels on hardened steel, stainless steel, cast iron, non-ferrous metals, fired ceramics, hardwoods, and rigid plastics—materials that would quickly dull standard cutters.

Whether you are engraving glass, carving stone, shaping metal, molding plastic, or grinding ceramics, the Dremel 9904 maintains its sharpness even after heavy use, delivering consistent results throughout demanding applications.

Features and Benefits

• Tungsten Carbide Construction: Extremely hard material engineered for longevity and sustained sharpness through demanding grinding and cutting tasks.
• Versatile Material Compatibility: Works on hardened steel, stainless steel, cast iron, non-ferrous metals, fired ceramics, hardwoods, and plastics in a single accessory.
• Optimal Cutting Technique: Using the sides of the cutter rather than the tip yields superior material removal and more effective results.
• Speed-Rated Performance: Rated for up to 35,000 RPM, with best results achieved by matching speed to material—higher speeds for hardwoods, slower speeds for metals and plastics.
