3M 7010309832 Scotch-brite Exl Unitized Wheel 8 in

Product Description

The 3M 7010309832 is a Scotch-Brite EXL Unitized Abrasive Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. The wheel measures 8 inches in diameter with a 3/4 inch arbor bore and uses aluminum oxide (AO) abrasive mineral. Its soft, conformable construction keeps the abrasive in consistent contact with irregular or complex part geometries, making it well suited for both manual and automated finishing operations. At 0.18 pounds, it is a lightweight option that minimizes operator fatigue in repetitive applications.

This wheel is used in metalworking, fabrication, and finishing applications across industrial, commercial, and light manufacturing environments. It is appropriate for deburring cut edges, blending welds, and preparing surfaces before coating or inspection. The wheel performs on a wide range of substrates including steel, aluminum, stainless steel, and many engineering-grade plastics and composites. It is commonly installed on bench grinders, angle grinders, or robotic finishing cells by machinists, fabricators, and finishing technicians.

Key Features

• Aluminum oxide (AO) abrasive mineral for consistent cut on metal alloys and composites
• Unitized, layered construction operates in both clockwise and counterclockwise directions
• Conformable consistency maintains abrasive contact on complex and irregular part shapes
• Minimizes heat build-up to protect heat-sensitive base materials during finishing
• Resists smearing for cleaner surface results and reduced prep time
• Wheel edge can be dressed to maintain geometry for deburring and polishing work

Compatibility

Designed for use on bench grinders, angle grinders, and robotic finishing spindles accepting a 3/4 inch arbor with an 8 inch diameter wheel. Suitable for finishing operations on metal alloys, plastics, and composites.

Installation Notes

Installation should be performed by a qualified machinist or finishing technician. Confirm the grinder or spindle is powered off and fully stopped before mounting or removing the wheel. Verify the machine arbor size matches the 3/4 inch bore and that the rated RPM of the spindle does not exceed the wheel's maximum operating speed. Inspect the wheel for damage before each use and follow applicable ANSI B11 and OSHA abrasive wheel safety guidelines.
