3M 7100188311 Scotch-brite Exl Unitized Wheel 10 in

Product Description

The 3M 7100188311 is a Scotch-Brite EXL Unitized Abrasive Wheel designed for surface finishing, deburring, and edge blending on metal alloys, plastics, and composites. The wheel measures 10 inches in diameter with a 1 1/4 inch arbor bore and weighs approximately 2.907 pounds. Its layered, unitized construction uses aluminum oxide abrasive mineral bonded throughout the wheel body, delivering consistent cut and finish from the outer edge to the core. The conformable structure keeps the abrasive in contact with irregular or complex part geometries, making it well suited for both manual bench operations and automated robotic processing.

This wheel is used in metal fabrication, maintenance, and finishing applications across industrial and commercial environments. Typical use cases include deburring cut edges on sheet metal, blending weld seams, and finishing stainless steel, aluminum, and other metal alloys. The wheel also performs on many plastics and composite materials. It is commonly run on bench-mounted or pedestal grinders and is compatible with standard arbor configurations. The 10 inch diameter suits medium to heavy-duty finishing work where consistent surface results are required across production runs.

Key Features

• Layered unitized construction runs in clockwise or counterclockwise direction without loss of performance
• Conformable consistency maintains abrasive contact on complex-shaped and contoured parts
• Minimizes heat buildup during operation, reducing risk of damage to heat-sensitive materials
• Resists smearing for cleaner surface results and reduced prep between passes
• Wheel edge can be dressed to restore cutting action and extend usable life
• Available density and grade range allows selection from soft conformable to hard aggressive cut

Compatibility

Designed for use on bench grinders and pedestal grinders with a 1 1/4 inch arbor bore accepting 10 inch diameter unitized wheels. Suitable for finishing metal alloys, many plastics, and composite materials.

Installation Notes

Mounting and operation of abrasive wheels should be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and disconnect the grinder before mounting or removing the wheel. Confirm the machine spindle speed does not exceed the maximum RPM rating marked on the wheel, and inspect the wheel for damage before each use. Eye protection and appropriate PPE are required during operation.
