3M 7100188513 Scotch-brite Exl Unitized Wheel 4 in Fine

Product Description

The 3M 7100188513 is a Scotch-Brite EXL Unitized Abrasive Wheel designed for smoothing, deburring, and finishing metal alloys, plastics, and composites. The wheel uses silicon carbide abrasive at a fine grit rating and features a soft, conformable construction that keeps the abrasive in continuous contact with the workpiece surface. At 4 inches in diameter, it mounts to bench grinders, angle grinders, and automated finishing equipment. The layered, unitized build resists smearing and minimizes heat buildup, making it suitable for heat-sensitive base materials. This wheel is primarily used by metalworkers, fabricators, and finishing technicians across industrial and production environments.

This wheel suits applications requiring consistent edge work on complex-shaped parts, including robotic and automated processing setups. The fine grit silicon carbide construction is appropriate for finish passes on metal alloys as well as many plastics and composites. Its conformable consistency makes it effective where rigid abrasives fail to maintain full contact with irregular profiles. The wheel can run in either clockwise or counterclockwise rotation, which simplifies integration into existing equipment configurations.

Key Features

• Silicon carbide abrasive, fine grit — suited for finish-stage deburring and surface conditioning
• Soft, conformable construction maintains contact on complex and irregular part geometries
• Bidirectional operation — runs clockwise or counterclockwise without performance loss
• Minimizes heat buildup to protect heat-sensitive materials during finishing
• Resists smearing for cleaner surfaces and reduced post-process prep
• Layered unitized construction supports consistent wear and extended wheel life

Compatibility

Designed for use on metal alloys, plastics, and composites requiring deburring, smoothing, or surface finishing; compatible with bench grinders and automated finishing equipment accepting 4-inch unitized wheels.

Installation Notes

Installation should be performed by a qualified metalworking or finishing technician familiar with abrasive wheel mounting procedures. Power down and lock out the grinder or finishing tool before mounting or removing the wheel. Verify that the spindle speed rating of the equipment does not exceed the maximum RPM rating of the wheel before operation. Inspect the wheel for damage prior to each use and confirm the arbor size matches the wheel bore.
