Foredom AK11989 12 Piece Mounted Radial Disc Assortment

The Foredom AK11989 is a 12-piece assortment of mounted radial discs designed for use with flexible shaft machines and rotary handpieces. Radial discs feature thin, flexible bristles that reach into recessed areas, contours, and tight spaces where conventional wheels and burs cannot. Abrasive grains are embedded throughout the disc bristles, so no additional compounds or abrasives are required. This assortment covers a range of grits and three disc diameters, making it a versatile set for progressing through multiple finishing stages in a single kit.

Suitable for use on precious and non-precious metals, acrylics, and ceramics, these discs can be used to clean metal surfaces, remove light fire scale and oxidation, finish, blend, texture, pre-polish, and polish. Each mandrel accommodates up to 3 discs at a time to build a custom brush configuration.

Do not run handpiece in reverse. Maximum speed: 20,000 RPM.
