3M 7010299309 Surface Conditioning Disc 3.5 Inch Non-woven

Product Description

The 3M 7010299309 is a non-woven surface conditioning disc designed for cleaning, blending, deburring, and finishing on a variety of materials. Built on an open-web, non-woven fiber construction, this 3.5-inch disc conforms to irregular and contoured surfaces without undercutting or damaging the base material. The aluminum oxide abrasive is integrated into the fiber structure, allowing the disc to run cool and resist loading during extended use. It attaches via a hook and loop system for fast changeover during multi-step finishing operations. Licensed trade professionals and fabricators use it as a reliable first-step abrasive in metal and composite surface prep workflows.

This disc is suited for use on metal, composite, plastics, and other common trade materials. The right-angle format makes it compatible with standard right-angle grinders and disc sanders used in HVAC duct fabrication, plumbing pipe prep, and general mechanical finishing applications. The non-woven construction handles contoured or irregular workpiece geometry where conventional coated abrasives would leave gouges or uneven scratch patterns. It is sold individually and well suited to multi-step processes where disc grades are changed in sequence.
