3M 7000028483 Scotch-brite Unitized Wheel 4 in Fine Grit

Product Description

The 3M 7000028483 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and finishing metal alloys, plastics, and composites. Built with a soft, conformable construction, this 4-inch diameter wheel uses silicon carbide abrasive at a fine grit rating to cut cleanly without smearing or excessive heat buildup. The layered, unitized structure allows the wheel to run in both clockwise and counterclockwise directions, making it a versatile tool for bench grinder and right-angle grinder setups. Fabricators, machinists, and finishing technicians install and use this wheel for edge work and surface prep in production and job-shop environments.

This wheel is suited for deburring, light stock removal, and surface finishing on metal alloys including stainless, aluminum, and carbon steel, as well as many plastics and composites. Its conformable consistency allows the abrasive to maintain contact on complex contoured or robotic-processed parts, making it a practical choice for both manual and automated finishing lines. The fine grit produces a consistent, clean surface without introducing deep scratches or excessive heat into heat-sensitive base materials.

Key Features

• Silicon carbide abrasive at fine grit for smooth, controlled material removal
• Soft, conformable construction maintains abrasive contact on complex and contoured part geometries
• Unitized layered construction supports both clockwise and counterclockwise rotation
• Resists smearing for cleaner finished surfaces with less secondary prep
• Minimizes heat buildup, reducing risk of damage to heat-sensitive materials
• Wheel edge can be dressed for targeted deburring, finishing, and polishing

Compatibility

Designed for use on metal alloys, plastics, and composites; suitable for bench grinders and right-angle grinders accepting 4-inch unitized wheel arbor configurations.

Installation Notes

Installation is performed by machinists or finishing technicians using appropriate arbor hardware for the host grinder. Always power down and de-energize the grinder before mounting or removing the wheel. Verify that the grinder RPM rating meets or exceeds the maximum RPM of the wheel before operation. Wear appropriate PPE including eye protection and gloves during mounting and use.
