3M 7100159406 Scotch-brite Cut Polish Disc 9 Inch Ao Medium

Product Description

The 3M 7100159406 is a Scotch-Brite Cut and Polish Disc built for surface finishing, cleaning, and light deburring on a wide range of metals. The disc uses an aluminum oxide mineral abrasive to deliver aggressive cutting action while leaving a smooth, polished surface. Its open-web non-woven construction resists loading, which extends usable service life compared to conventional coated abrasive discs. Rated at medium grade, this disc is well-suited for satin and high-luster finishing work in fabrication, maintenance, and metalworking applications. It measures 9 inches in diameter with a 1-inch arbor. Machinists, fabricators, and metal finishing technicians are the primary installers.

This disc is designed for use on bench motors and straight shaft tools, making it versatile across fixed and handheld power equipment. It is commonly used in metal fabrication shops, maintenance facilities, and production environments where consistent surface finishing or blending is required. The high cut-rate combined with low heat retention allows extended contact with the workpiece without risk of heat discoloration or surface damage, which is particularly valuable when finishing stainless steel, aluminum, and other heat-sensitive alloys.
