3M 7100188535 Scotch-brite Exl Unitized Wheel 8 in

Product Description

The 3M 7100188535 is a Scotch-Brite EXL Unitized Wheel designed for surface finishing, deburring, and edge blending on metal alloys, plastics, and composites. Built with aluminum oxide abrasive in a soft, conformable unitized construction, this wheel maintains consistent contact with irregular and complex part geometries. At 8 inches in diameter with a 1-inch arbor bore, it mounts directly to bench grinders, pedestal grinders, and automated finishing equipment. The layered construction resists smearing and minimizes heat buildup, making it a dependable choice for production and job-shop finishing operations where surface quality and part integrity matter.

This wheel is suited for metalworking shops, fabrication facilities, and automated robotic finishing cells. It is used on ferrous and non-ferrous metals, as well as many plastics and composites. The unitized design allows the wheel edge to be dressed, extending service life and maintaining a consistent cut profile throughout use. Applications include weld blending, edge deburring, and pre-paint or pre-plate finishing where a uniform surface condition is required.

Key Features

• Soft, conformable construction keeps abrasive in contact with complex or irregular part surfaces
• Wheel edge can be dressed for consistent deburring, finishing, and polishing performance
• Operates in both clockwise and counterclockwise rotation directions
• Minimizes heat buildup to protect heat-sensitive base materials
• Resists smearing for cleaner surfaces and reduced prep time
• Compatible with robotic and automated processing environments

Compatibility

Designed as a unitized abrasive wheel for bench grinders, pedestal grinders, and automated finishing machines equipped with a 1-inch arbor and capable of accepting an 8-inch diameter wheel.

Installation Notes

Installation should be performed by a qualified operator following the grinder or finishing machine manufacturer's mounting instructions. Power down and lock out the machine before mounting or removing the wheel. Verify that the machine's maximum operating RPM meets or exceeds the rated speed of the wheel before operation. Inspect the wheel for damage prior to each use and do not exceed the rated arbor bore size.
