3M 7000120677 Scotch-brite Exl Unitized Wheel 4 Inch Fine Grit

Product Description

The 3M 7000120677 is a Scotch-Brite EXL Unitized Wheel designed for deburring, smoothing, and finishing metal alloys, plastics, and composites. Built with a soft, conformable construction, the wheel maintains consistent abrasive contact across irregular and complex part geometries. The silicon carbide abrasive in a fine grit rating delivers controlled surface refinement without excessive material removal. This wheel is well suited for bench grinder and angle grinder applications in fabrication shops, maintenance facilities, and light manufacturing environments where surface finish quality matters. Licensed trade professionals and skilled fabricators are the primary users.

This unitized wheel is intended for use on metal alloys including stainless steel, aluminum, and other non-ferrous metals, as well as many plastics and composites. The fine grit designation makes it appropriate for finishing and polishing passes rather than heavy stock removal. It fits standard 4-inch wheel applications and can be run in robotic or automated processing setups due to its consistent conformability. The wheel operates in either clockwise or counterclockwise rotation, providing flexibility in machine setup and orientation.

Key Features

• Silicon carbide abrasive in fine grit for controlled finishing and polishing
• Soft, conformable unitized construction conforms to complex and irregular part shapes
• Runs clockwise or counterclockwise for flexible machine compatibility
• Resists smearing for cleaner surface results and reduced prep work
• Minimizes heat buildup, reducing risk of damage to heat-sensitive materials
• Wheel edge can be dressed to maintain effective deburring and finishing performance

Compatibility

Designed as an OEM-style replacement and standard-fit unitized wheel for 4-inch bench grinder and angle grinder applications involving metal alloys, plastics, and composites.

Installation Notes

Installation is performed by fabricators and maintenance technicians using standard arbor mounting hardware appropriate for 4-inch unitized wheels. Always power down and de-energize the grinder before mounting or removing the wheel. Verify the machine speed rating does not exceed the maximum rated speed of the wheel before operation. Follow applicable ANSI B11 and OSHA abrasive wheel safety guidelines when mounting and guarding the wheel.
