3M 7000121004 Radial Bristle Disc 9/16x1/16 Inch Polish 2

Product Description

The 3M 7000121004 is a radial bristle disc designed for deburring, light material removal, and surface finishing on metal and other substrates. The disc measures 9/16 inches in diameter with a 1/16 inch thickness and is rated Polish 2 grade, which produces a coarse satin finish on the worked surface. Fabricated from durable radial plastic bristle construction, it is built to withstand repeated use in production and maintenance environments. Licensed tradespeople and shop technicians use this disc when precision surface prep is needed without aggressive stock removal. Multiple discs can be ganged together to build a wider working brush to suit the job at hand.

This disc fits portable handheld rotary tools and small bench motors, making it suitable for both in-shop and field use. Typical applications include weld cleanup, edge deburring, light coating removal, and surface conditioning on metal workpieces. The Polish 2 grade is appropriate when the goal is a consistent coarse satin surface texture rather than a high-gloss polish or heavy stock removal. It is commonly used by machinists, fabricators, pipefitters, and maintenance technicians working on ferrous and non-ferrous metals.
