3M 7100146004 Roloc 361F Abrasive Disc 3 Inch P180 Grit

Product Description

The 3M 7100146004 is a Roloc quick-change coated abrasive disc designed for grinding, blending, deburring, and finishing operations on all metals. The disc uses fast-cutting aluminum oxide abrasive grains bonded to a YF-weight polyester cloth backing with a heat-resistant resin system. At 3 inches in diameter and rated to 20000 RPM, it is built for use with compatible quick-change angle grinders and die grinders in both wet and dry conditions. P180 grit positions this disc for intermediate to fine finishing work where consistent surface quality is required.

This disc is suited for metal fabrication shops, maintenance and repair operations, and production finishing environments where fast disc changes and reliable cut rates matter. It handles medium-pressure applications on ferrous and non-ferrous metals and is equally effective in wet coolant setups or dry grinding operations. Licensed metalworkers, fabricators, and maintenance mechanics are the primary installers and users of this product.

Installation Notes

Installation is performed by trade professionals and fabricators familiar with angle grinder and die grinder operation. Ensure the grinder is powered off and disconnected from its power source before changing discs. Confirm the tool RPM rating meets or exceeds the disc rating of 20000 RPM before use. Always inspect the disc for damage before mounting and follow applicable ANSI and OSHA abrasive wheel safety standards during operation.
