3M 7100006569 Quick-change Disc 4 in 80 Grit Ceramic Roloc Tr

Product Description

The 3M 7100006569 is a quick-change coated abrasive disc engineered for high-speed material removal on metal, weld seams, and surface prep work. Part of the 984F series, it uses a ceramic abrasive grain on a polyester cloth backing rated YF weight, delivering consistent cut rate and durability under sustained load. The disc mounts via a Roloc TR Type R attaching system, allowing single-motion tool attachment and release without hardware. At 80 grit medium grade, it is suited for aggressive stock removal, edge blending, and weld dressing. Maximum operating speed is 12,000 RPM. Licensed trades and metalworking professionals are the primary installers.

This disc is designed for use with Roloc TR and Type R compatible right-angle grinders and die grinders in industrial, fabrication, and maintenance applications. Typical use cases include grinding weld splatter, deburring cut edges, and preparing steel or aluminum surfaces for coating or inspection. It performs on flat, contoured, and hard-to-reach surfaces where a larger wheel cannot be positioned. The 4-inch diameter suits medium-access grinding tasks common in HVAC duct fabrication, mechanical room pipe work, and general sheet metal operations.

Installation Notes

Installation requires a Type R mandrel or compatible Roloc TR backup pad secured to the grinder spindle. Verify the tool spindle speed does not exceed the 12,000 RPM disc rating before operation. Always power down and disconnect the grinder from its power source before mounting or removing a disc. Eye protection and appropriate PPE are required during use in accordance with applicable ANSI and OSHA standards.
