3M 7000028452 Scotch-brite Exl Unitized Wheel 6 in Ao

Product Description

The 3M 7000028452 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. The wheel uses aluminum oxide abrasive in a soft, conformable layered construction that keeps abrasive contact consistent across irregular and complex part geometries. At 6 inches in diameter with a 1/2 inch arbor, it mounts directly to bench grinders, right-angle tools, and automated finishing equipment. The unitized construction runs in either clockwise or counterclockwise rotation, making it flexible for a range of setups.

This wheel is suited for fabrication shops, metal service centers, and production finishing operations handling deburring, edge blending, and light surface prep on ferrous and non-ferrous metals as well as select plastics and composites. It is appropriate for both manual bench work and robotic or automated processing lines where conformability to complex shapes is required. Available in densities from 2 (soft, conformable) to 8 (hard, aggressive), this listing represents a specific density and grade within the EXL line.

Key Features

• Soft, conformable construction maintains abrasive contact on complex and contoured part surfaces
• Bidirectional rotation — operates clockwise or counterclockwise without performance loss
• Resists smearing for cleaner surfaces and reduced prep between operations
• Minimizes heat buildup, reducing thermal impact on heat-sensitive base materials
• Wheel edge can be dressed to restore profile for deburring, finishing, and polishing applications
• Layered unitized build provides consistent cut rate as the wheel wears

Compatibility

Designed for use on bench grinders and finishing equipment with a 1/2 inch arbor accepting 6 inch diameter unitized wheels. Suitable for metal alloys, many plastics, and composites in both manual and automated finishing applications.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B7.1 standards. Power down and lock out the machine before mounting or changing the wheel. Verify that the tool spindle speed does not exceed the maximum RPM rating marked on the wheel. Inspect the wheel for damage before each use and confirm the arbor size matches the 1/2 inch bore before securing.
