3M 7100031086 Scotch-brite Exl Unitized Wheel Fine Grit

Product Description

The 3M 7100031086 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and finishing operations on metal alloys, plastics, and composites. At 3 inches in diameter, this wheel uses silicon carbide abrasive at a fine grit rating, making it well suited for surface conditioning tasks where controlled material removal and a clean finish are the priority. Its soft, conformable construction allows the abrasive to maintain consistent contact across irregular or complex part geometries. Licensed metalworkers, fabricators, and finishing technicians are the primary users in production and job-shop environments.

This unitized wheel is used in both manual and automated finishing applications, including robotic processing lines where consistent abrasive contact with complex-shaped parts is required. It performs on a broad range of substrates including steel, aluminum, and other metal alloys, as well as many plastics and composites. The fine grit rating targets finish-stage work such as edge blending, light deburring, and pre-polish surface preparation rather than aggressive stock removal.

Key Features

• Silicon carbide abrasive provides consistent cut on metal alloys, plastics, and composites
• Soft, conformable construction maintains abrasive contact on complex and irregular part profiles
• Tough, layered, unitized build supports operation in both clockwise and counterclockwise directions
• Minimizes heat build-up to protect heat-sensitive workpiece materials
• Resists smearing for cleaner surface results with less prep work between steps
• Wheel edge can be dressed for targeted deburring, finishing, and polishing applications

Compatibility

Designed for use on right-angle grinders and bench-mounted spindles or arbors that accept 3-inch unitized wheels. Suitable for finishing operations on metal alloys, plastics, and composites in both manual and robotic processing setups.

Installation Notes

Installation should be performed by a qualified operator following the tool manufacturer's mounting instructions for unitized abrasive wheels. Confirm that the spindle speed of the grinder or arbor does not exceed the maximum rated RPM of the wheel before operation. Power down and de-energize all equipment before mounting or removing the wheel. Always inspect the wheel for damage prior to each use and verify secure mounting before starting the tool.
