3M 7000045977 Scotch-brite Roloc Unitized Wheel 2 in Fine

Product Description

The 3M 7000045977 is a Scotch-Brite Roloc EXL Unitized Wheel designed for edge deburring and surface finishing on metal and machined parts. The compressed, open-web construction uses aluminum oxide abrasive at a fine grit level, delivering consistent cutting action throughout the wheel's life. Unitized construction means the abrasive, fiber, and resin are integrated into a single dense form that holds its shape under load. This wheel weighs 0.04 pounds and is built for use on pneumatic or electric right-angle grinders equipped with a Roloc-style spindle. It is installed and serviced by machinists, fabricators, and metalworking technicians where close tolerances on finished edges are required.

This wheel suits a wide range of metalworking applications including edge deburring, light stock removal, and surface finishing on flat, contoured, or irregular part geometries. Fine grit makes it well suited for finishing passes where surface quality matters and material removal must be controlled. The 2-inch diameter fits compact tooling used on small machined components, weld seams, and tight-access areas. Both hard and soft density variants exist within the EXL line, allowing selection based on whether edge retention or surface conformability is the priority.

Key Features

• Unitized construction integrates abrasive and fiber for consistent shape and cutting action throughout wheel life
• Aluminum oxide abrasive at fine grit for controlled material removal and smooth surface finish
• Compressed, open-web design with uniform grain distribution maintains consistent scratch pattern
• Roloc attachment system enables quick disc change-out during multi-step finishing processes without tools
• 2-inch diameter suits small machined parts, weld areas, and tight-access finishing applications

Compatibility

Designed for use with Roloc-compatible right-angle grinders and die grinders fitted with a Roloc-style threaded spindle attachment.

Installation Notes

Installation is performed by machinists or metalworking technicians. Power down and disconnect the grinder from its air or electrical supply before mounting or removing the wheel. Thread the Roloc spindle into the wheel hub by hand until fully seated before resuming operation. Inspect the wheel for damage before each use and do not exceed the rated RPM marked on the wheel or its packaging.
