Dremel 9905 Tungsten Carbide Spherical Cutter

The Dremel 9905 is a tungsten carbide spherical cutter designed for precision shaping, smoothing and material removal across a wide range of hard materials. This 3.2mm rotary cutter head is engineered to tackle demanding applications where standard cutting accessories would struggle, making it an essential accessory for detailed fabrication and finishing work. Ideal for working with hardened steel, stainless steel, cast iron and nonferrous metals, this spherical cutter also handles fired ceramics, plastics and hardwoods with ease. The tungsten carbide construction delivers exceptional durability and cutting performance on materials that would quickly wear down conventional cutters, making it particularly valuable for precision metalwork and intricate shaping tasks. With a maximum operating speed of 30,000 RPM, this cutter is compatible with Dremel rotary tools and similar multi-tools fitted with 3.2mm collets. The spherical profile provides excellent control for creating contoured surfaces, enlarging holes, and removing material in tight spaces where larger tools cannot reach.
