3M 7000120363 Diamond Coated Disc 2 in 60 Grit Roloc Tr

Product Description

The 3M 7000120363 is a quick-change coated abrasive disc designed for high-speed grinding, blending, and finishing applications. Built on a flexible polyester backing with a J-weight rating, this disc uses diamond abrasive material at 60 grit and Grade M250 for consistent cutting performance on hard or abrasive workpiece materials. The disc measures 2 inches in diameter and is rated for a maximum speed of 25,000 RPM. It mounts via a TR (Type III) Roloc-style attaching system, allowing fast one-handed disc changes without tools. The brown disc with green button is part of the 3M 6234J series.

This disc is suited for precision surface work in fabrication, maintenance, and repair environments. The flexible polyester backing conforms to contoured surfaces, making it appropriate for deburring, weld blending, and finish work on hard materials. At 2 inches in diameter, it fits compact right-angle grinders and die grinders equipped with a compatible Roloc TR mandrel. Typical users include machinists, maintenance technicians, and metalworking professionals requiring repeatable abrasive performance at high rotational speeds.
