3M 7000120349 Abrasive Disc 80 Grit 8 Inch

Product Description

The 3M 7000120349 is an 8-inch coated abrasive disc engineered for material removal and surface refinement in professional finishing applications. Built on a durable E-weight paper backing, it uses a ceramic and aluminum oxide blend abrasive bonded with resin for consistent cut rate and extended disc life. The open coat construction resists loading and clogging, making it effective on fresh body filler, putty, and bare metal. At 80 grit, this disc handles aggressive shaping, paint stripping, and scratch refinement without excessive surface damage. It is used by auto body technicians, metal fabricators, and trade painters who need reliable abrasive performance on demanding surfaces.

This disc is suited for use on plastic body filler, putty, painted surfaces, and bare metal substrates. The Hookita hook-and-loop attachment system allows fast disc swaps without tools, reducing downtime during high-volume work. Certain configurations in the 255U series include a 7- or 8-hole pattern to support dust evacuation when used with compatible vacuum-ready sanders. The disc measures 8 inches in diameter and is packaged in box quantities with a minimum order of 5 units.
