3M 7000120328 Abrasive Disc 8 Inch P80 Grit Ceramic Ao

Product Description

The 3M 7000120328 is a coarse-grit abrasive disc designed for automotive body and metal surface preparation work. Built on a heavy D-weight paper backing, this 8-inch disc uses a ceramic aluminum oxide mineral blend to deliver a fast cut rate and extended service life compared to standard aluminum oxide discs. The pressure-sensitive adhesive (PSA) backing allows quick disc changes on compatible random orbital and DA sanders. Grit designation is P80, placing it in the coarse range suited for aggressive material removal and surface shaping tasks. Installers and body shop technicians reach for this disc when speed and durability matter on demanding surfaces.

This disc is used in automotive collision repair and refinishing workflows. Primary applications include shaping plastic body filler, removing paint from damaged panels, and refining scratches on bare metal and fiberglass substrates. The D-weight backing resists tearing and flex fatigue during extended sanding sessions, making it suitable for both flat panel work and moderate contour sanding. The disc is sold in box quantities with a minimum order of 5 units.
