3M 7010329632 Surface Conditioning Disc 3.5 Inch Non-woven

Product Description

The 3M 7010329632 is a non-woven surface conditioning disc designed for right-angle grinder use on metal, composite, plastic, and other materials. At 3.5 inches in diameter, the open-web aluminum oxide construction conforms to irregular and contoured surfaces without undercutting or gouging the base material. This disc is well suited for cleaning, blending, deburring, and finishing operations in fabrication, maintenance, and light manufacturing environments. HVAC sheet metal techs, pipefitters, and general trade professionals who work with ductwork, fittings, or structural components will find it a practical first-step abrasive for surface prep.

This disc is used in multi-step finishing workflows where surface conditioning precedes coating, welding, or inspection. The hook-and-loop attachment system allows fast disc changes when moving between abrasive grades or surface prep stages. Its open-web structure runs cool and resists loading, extending usable life during prolonged operation. Suitable for flat, curved, or contoured workpieces across metal and non-metal substrates.
