3M 7000119021 Quick-change Disc 150 Grit 2 in Roloc Tr

Product Description

The 3M 7000119021 is a coated abrasive quick-change disc designed for use with Roloc TR (Type III) attaching systems. Part of the 3M 361F Series, it features an aluminum oxide abrasive grain bonded to a polyester cloth backing rated YF weight. At 150 grit, it falls in the very fine grade range, making it suited for finishing, light stock removal, and surface blending on metal and similar substrates. The disc measures 2 inches in diameter and is rated for a maximum operating speed of 25,000 RPM. It ships individually but requires a minimum order quantity of 50 units.

This disc is intended for use in fabrication, maintenance, and surface preparation applications where a quick-change format reduces disc swap time. The 2-inch diameter fits standard right-angle die grinders and inline grinders equipped with a Roloc TR or Type III mandrel. Very fine 150 grit makes it appropriate for final blending passes, weld spatter cleanup, and pre-paint surface conditioning on metal. It is commonly used by metalworkers, millwrights, and maintenance technicians in both shop and field environments.

Installation Notes

Installation requires a compatible Roloc TR (Type III) mandrel mounted in a die grinder or similar rotary tool. Confirm the tool's free-speed RPM does not exceed the 25,000 RPM disc rating before use. Inspect the disc for damage before each use and replace any disc showing tears, delamination, or abrasive loss. Always wear appropriate eye and face protection when operating abrasive discs.
