3M 7100173796 Clean and Strip Xt Pro Disc 4 in Roloc

Product Description

The 3M 7100173796 is an extra coarse grade aluminum oxide Scotch-Brite Roloc Clean and Strip XT Pro disc designed for aggressive surface preparation and cleaning on metal and other hard substrates. The disc mounts via the Roloc twist-on hub system, allowing fast disc changes on compatible right-angle grinders and die grinders without tools. At 4 inches in diameter and rated XC-DR (extra coarse), it removes rust, scale, weld discoloration, paint, and light mill scale while leaving a surface ready for coating or further finishing. Trade professionals working in fabrication, HVAC sheet metal, plumbing rough-in prep, and general maintenance rely on this disc for quick material removal without the loading issues common with bonded abrasives.

This disc is suited for use on ferrous and non-ferrous metals in both residential and light commercial service environments. The green aluminum oxide construction handles demanding stripping applications on ductwork, pipe flanges, structural steel, and welded assemblies. It is packaged 10 discs per carton and 40 discs per case, making it practical for job-site stocking. The Die Q400BB designation corresponds to the 4-inch Roloc format used with standard TR-style backing pads.
