3M 7100033190 Roloc Abrasive Disc 3 in 36 Grit

Product Description

The 3M 7100033190 is an Imperial Roloc abrasive disc designed for metal grinding applications in trade and fabrication environments. Measuring 3 inches in diameter with a 36 grit rating, this disc is built for aggressive stock removal on steel and other ferrous metals. The one-piece molded backing increases structural integrity, reducing disc flex and extending service life under sustained load. Licensed trades including pipefitters, ironworkers, welders, and HVAC sheet metal fabricators rely on this type of disc for weld dressing, surface prep, and deburring tasks.

This disc is suited for use in residential and commercial metal fabrication, mechanical rooms, and field service environments where a fast-cutting coarse-grit abrasive is needed. The Roloc quick-change attachment system allows for rapid disc swaps without tools, keeping downtime low on multi-step surface preparation work. The 36 grit designation makes it appropriate for initial grinding passes, weld bead removal, and heavy material removal rather than finish work.
