3M 7000120327 Abrasive Disc 6 Inch 40 Grit Coarse Psa

Product Description

The 3M 7000120327 is a 6-inch pressure-sensitive adhesive (PSA) coated abrasive disc designed for heavy material removal and surface preparation work. Built on an E-weight backing, this disc is engineered for durability under aggressive sanding conditions. The ceramic aluminum oxide mineral blend delivers a fast cut rate and extended disc life compared to conventional abrasive minerals. At 40 grit coarse, it is suited for stripping paint down to bare metal, shaping plastic body filler, and smoothing fiberglass surfaces. Automotive body technicians and metalworkers are the primary installers of this consumable product.

This disc is used in automotive bodywork, collision repair, and fabrication environments where fast, consistent material removal is required. The PSA mount allows quick disc changes on compatible 6-inch backup pads without the need for additional fasteners or hook-and-loop systems. The coarse 40 grit rating makes it most effective in early-stage surface preparation before finishing grits are applied. It is sold in box quantities with a minimum order quantity of 5 units.
