3M 7010329631 Surface Conditioning Disc 7.5 Inch

Product Description

The 3M 7010329631 is a Scotch-Brite Surface Conditioning Disc built for right-angle grinder applications. Constructed from durable, open-web non-woven fiber, it conforms to irregular and contoured surfaces without undercutting or damaging the base material. At 7.5 inches in diameter, the disc handles cleaning, blending, deburring, and light finishing tasks across metal, composite, plastics, and other substrates. The open web structure allows heat to dissipate during use and resists loading, extending disc life on prolonged runs. A hook-and-loop attachment system allows fast disc swaps in multi-step finishing processes, reducing downtime between grits or grades.

This disc is suited for trade and industrial use wherever surface conditioning is required before coating, welding inspection, or final finishing. Typical applications include preparing metal fabrications, blending welds, removing light burrs, and conditioning composite panels. The aluminum oxide abrasive construction makes it a practical choice for general metalworking, HVAC ductwork fabrication, pipe preparation, and structural steel work. It is sold individually and is appropriate for licensed tradespeople and experienced fabricators working on both flat and contoured workpieces.
