3M 7000028460 Scotch-brite Exl Unitized Wheel 8 Inch Fine

Product Description

The 3M 7000028460 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 material removal without smearing or excessive heat buildup. Its soft, conformable construction allows the abrasive surface to follow complex part geometries, making it suitable for both manual bench work and automated robotic processing. The wheel measures 8 inches in diameter and weighs 0.08 pounds. HVAC sheet metal fabricators, pipefitters, and metalworking tradespeople are the primary users of this type of abrasive wheel.

This unitized wheel is used in applications requiring controlled deburring, edge finishing, and light polishing on fabricated metal components including ductwork, pipe fittings, and structural brackets. The fine grit rating makes it appropriate for final-pass finishing where surface quality matters. It is equally effective on many plastics and composites, broadening its use across fabrication shops that work with mixed materials. The wheel can be dressed at the edge for targeted deburring work on tight profiles or irregular part edges.

Key Features

• Silicon carbide abrasive provides consistent cut on metal alloys, plastics, and composites
• Fine grit rating suited for finishing and light deburring passes
• Soft, conformable unitized construction follows complex and irregular part shapes
• Operates in both clockwise and counterclockwise directions for flexible mounting
• Resists smearing for cleaner finished surfaces with less prep work
• Minimizes heat buildup to protect heat-sensitive workpieces
• Wheel edge can be dressed for precise deburring on detailed profiles

Compatibility

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

Installation Notes

Installation should be performed by qualified personnel following the grinder or finishing equipment manufacturer's mounting instructions. Always power down and lock out the equipment before changing abrasive wheels. Inspect the wheel for damage before mounting and confirm the equipment spindle speed does not exceed the rated maximum speed for the wheel. Appropriate eye protection, face shield, and respiratory protection should be worn during operation per applicable safety standards.
