3M 7100188543 Scotch-brite Exl Unitized Wheel 14 in

Product Description

The 3M 7100188543 is a Scotch-Brite EXL Unitized Wheel designed for deburring, finishing, and polishing metal alloys, plastics, and composites. Built with a layered, conformable construction and aluminum oxide abrasive, this 14-inch diameter wheel mounts on a 1/4-inch arbor and is suited for bench grinders and automated robotic processing equipment. The unitized wheel design maintains consistent cut rate and surface finish throughout the life of the wheel, making it a reliable choice for production metalworking and fabrication shops. At 3.309 pounds, it is a single-unit consumable rated for both clockwise and counterclockwise rotation.

This wheel is used in metal fabrication, aerospace component finishing, and general industrial surface preparation. It performs well on edges and contoured surfaces where conformability is critical. The wheel resists smearing and minimizes heat buildup, making it appropriate for heat-sensitive base materials. Applications include edge deburring of machined parts, pre-plate or pre-coat surface conditioning, and final polishing of stainless steel, aluminum, and other alloys. It is also compatible with many engineered plastics and composite materials.

Key Features

• Layered, unitized construction operates clockwise or counterclockwise for flexible machine setup
• Conformable consistency keeps abrasive in contact with complex and irregular part geometries
• Aluminum oxide abrasive mineral for effective cut on metal alloys, plastics, and composites
• Resists smearing for cleaner surface results and reduced prep time between operations
• Minimizes heat buildup to protect heat-sensitive workpieces during processing
• Wheel edge can be dressed to restore cutting action and extend usable life

Compatibility

Designed as an OEM-style replacement unitized abrasive wheel for bench grinders, pedestal grinders, and automated finishing equipment accepting a 1/4-inch arbor and accommodating a 14-inch diameter wheel.

Installation Notes

Installation should be performed by a qualified machinist or abrasive tooling technician following ANSI B7.1 safety requirements for the use, care, and protection of abrasive wheels. Power down and lock out the grinder or finishing machine before mounting the wheel. Confirm spindle speed does not exceed the maximum RPM rating marked on the wheel, and inspect the wheel for cracks or damage before each use. Never use a damaged or improperly mounted wheel.
