Foredom AK11986M 92 Piece Unmounted Radial Disc Assortment

The Foredom AK11986M 92-Piece Unmounted Radial Disc Assortment gives jewelers, metalsmiths, and finishing professionals a comprehensive selection of radial bristle discs in three diameters and a wide range of grits. Radial discs feature thin bristles that reach into recessed areas and detailed surfaces, and their abrasive grains are embedded throughout — no additional compounds needed. Use them to clean metal surfaces, remove light fire scale and oxide, finish, blend, texture, pre-polish, and polish precious and non-precious metals, acrylics, and ceramics.

This assortment includes three diameters — 25 mm (1"), 20 mm (3/4"), and 15 mm (5/8") — spanning grits from 80 through 5000, covering aggressive material removal to final polishing. Each mandrel accommodates 3–6 discs, allowing you to customize the brush density to your task.
