3M 7100086327 Scotch-brite Exl Unitized Wheel 8 Inch Fine Grit

Product Description

The 3M 7100086327 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. Built with silicon carbide abrasive at a fine grit rating, this wheel delivers consistent, controlled material removal without smearing or excessive heat buildup. The layered, unitized construction holds its form under load, making it a reliable choice for both manual bench grinder setups and automated robotic finishing cells. At 0.88 pounds, it fits standard arbor configurations used in metal fabrication and surface prep work.

This wheel is suited for finishing and deburring operations in metal fabrication shops, manufacturing facilities, and maintenance environments. It performs on ferrous and non-ferrous metals as well as many plastics and composites. The fine grit rating makes it appropriate for finishing passes where edge definition and surface cleanliness matter. Its conformable consistency allows the abrasive to maintain contact on contoured or complex-shaped workpieces, which is particularly useful in robotic or CNC-assisted processing lines.

Key Features

• Silicon carbide abrasive construction delivers fine-grit finishing and deburring on metal, plastic, and composite surfaces
• Unitized, layered build runs in both clockwise and counterclockwise directions for flexible machine setup
• Conformable consistency keeps abrasive in contact with complex or contoured part geometries
• Resists smearing, leaving cleaner surfaces with less secondary prep required
• Minimizes heat buildup, reducing thermal impact on heat-sensitive base materials
• Wheel edge can be dressed to maintain cutting geometry over the life of the wheel

Compatibility

Designed for use on bench grinders, pedestal grinders, and automated finishing equipment accepting an 8-inch diameter unitized abrasive wheel. Suitable for metal alloys, many plastics, and composite materials.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B7.1 standards. Always power down and de-energize the grinder before mounting or removing the wheel. Verify that the machine spindle speed rating meets or exceeds the wheel speed rating before operation. Inspect the wheel for damage before each use and do not use a cracked or compromised wheel.
