3M 7100070473 Roloc Quick Change Disc P100 3 Inch

Product Description

The 3M 7100070473 is a Roloc 361F quick-change abrasive disc engineered for grinding, deburring, blending, and finishing on metal surfaces. The disc uses closed-coat aluminum oxide abrasive grains bonded to a YF-weight polyester cloth backing with heat-resistant resin. At 3 inches in diameter and rated to 20000 RPM, it delivers a fast cut rate on ferrous alloys and a wide range of metals. The aluminum oxide mineral self-fractures during use to expose fresh cutting edges, extending disc life compared to conventional natural abrasives. The resin bond maintains stability under high heat and pressure, supporting both wet and dry operation.

This disc is suited for industrial and trade applications involving metal grinding, surface blending, and edge deburring. The YF-weight polyester cloth backing provides the flexibility and durability needed for contoured surfaces and heavy stock removal. It is appropriate for use on disc sanders and compatible rotary tools in fabrication shops, maintenance environments, and production grinding operations where a consistent, long-lasting abrasive is required.

Designed for use with 3M Roloc attachment systems TSM, TR, TP, and TS. Select the disc with the attachment design matched to the correct system in use.

Installation Notes

Installation is performed by pressing the Roloc disc onto the appropriate quick-change mandrel until the attachment locks. Verify the disc is fully seated and the mandrel is rated for the disc speed before operation. Inspect the disc for damage before each use and do not exceed the 20000 RPM maximum speed rating. Ensure the grinder or disc sander is powered off and unplugged before mounting or removing the disc.
