3M 7000120679 Scotch-brite Exl Unitized Wheel 12 Inch

Product Description

The 3M 7000120679 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. Built with silicon carbide abrasive mineral and a layered, unitized construction, this wheel delivers consistent cut and finish throughout its full service life. At 12 inches in diameter and 1.69 inches in width, it fits stationary bench grinders and automated finishing equipment. The conformable structure keeps the abrasive in contact with irregular or complex part profiles, making it effective for both manual and robotic processing applications.

This wheel is suited for metal fabrication shops, aerospace component finishing, and industrial surface preparation work. It handles deburring, edge blending, and final finishing passes on steel, aluminum, titanium alloys, and many engineering plastics and composites. The unitized construction allows operation in both clockwise and counterclockwise rotation, giving flexibility in machine setup. Its ability to resist smearing makes it a practical choice for applications where surface cleanliness before coating or inspection is critical.

Key Features

• Silicon carbide abrasive mineral for effective cut on metals, plastics, and composites
• Layered, unitized construction runs clockwise or counterclockwise without performance loss
• Conformable structure maintains abrasive contact on complex and irregular part geometries
• Minimizes heat buildup, reducing risk of thermal damage to heat-sensitive materials
• Resists smearing for cleaner surface finishes with less follow-up preparation
• Wheel edge can be dressed to maintain consistent deburring and polishing profiles

Compatibility

Designed as an OEM-style replacement or direct-fit unitized finishing wheel for stationary grinders and automated finishing machines that accept 12-inch diameter wheel mountings.

Installation Notes

Mounting and operation of abrasive wheels should be performed by trained personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always inspect the wheel for damage before mounting and confirm the machine spindle speed does not exceed the maximum rated speed marked on the wheel. Power down and lock out the machine before mounting or removing the wheel. Use the appropriate flanges and blotters as specified by the wheel and machine manufacturer.
