3M 7010365457 Coated Abrasive Disc 4 Inch P320 Grit

Product Description

The 3M 7010365457 is a 4-inch coated abrasive disc designed for grinding, blending, deburring, and finishing on all metals. Fast-cutting aluminum oxide abrasive grains are bonded to a heavyweight YF-weight polyester cloth backing using a heat-resistant resin. This construction supports both wet and dry applications and holds up under sustained pressure and elevated heat. The quick-change Roloc attachment system allows fast, secure mounting and removal without tools. Rated at 15000 RPM, this disc is built for consistent performance in demanding metal fabrication and finishing work performed by machinists, welders, and metal fabricators.

This disc is suited for use on all metals in both residential and light commercial fabrication environments. Common applications include weld blending, surface conditioning, deburring cut edges, and preparation work before coating or finishing. The medium-pressure YF-weight polyester backing provides stability during use, making it a reliable choice for repetitive finishing tasks on flat and contoured metal surfaces. Its wet and dry compatibility adds flexibility across different shop and field conditions.
