3M 7010309362 Scotch-brite Exl Unitized Wheel 8 in Ao

Product Description

The 3M 7010309362 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 the abrasive in continuous contact with the workpiece surface, including complex or irregular profiles. At 8 inches in diameter with a 1-1/4 inch arbor bore, it mounts to standard bench grinders, pedestal grinders, and automated finishing equipment. This wheel is used by metal fabricators, machinists, and industrial finishing technicians in both manual and robotic processing setups.

This unitized wheel is suited for edge deburring, light stock removal, and pre-polish finishing on stainless steel, aluminum, titanium, and other metal alloys. It also performs on many plastics and composites where heat control is critical. The conformable construction makes it effective in robotic or automated processing lines where consistent contact pressure across irregular part geometry is required. It operates in both clockwise and counterclockwise directions, providing flexibility in multi-spindle or reversible-drive setups.

Key Features

• Soft, conformable unitized construction maintains abrasive contact on complex and irregular part profiles
• Aluminum oxide abrasive for effective deburring, smoothing, and finishing of metal alloys, plastics, and composites
• Bidirectional operation — runs clockwise or counterclockwise without performance loss
• Resists smearing for cleaner surface finishes and reduced post-process cleanup
• Minimizes heat buildup, reducing thermal impact on heat-sensitive base materials
• Wheel edge can be dressed to restore cutting geometry and extend service life

Compatibility

Designed for use on standard bench and pedestal grinders accepting a 1-1/4 inch arbor. Suitable for finishing applications on metal alloys including stainless steel and aluminum, as well as many plastics and composites.

Installation Notes

Installation is typically performed by the machine operator or maintenance technician. Power down and lockout the grinder before mounting or removing the wheel. Verify the grinder spindle speed rating does not exceed the maximum RPM rated for the wheel before operation. Inspect the wheel for damage before each use and do not operate a cracked or delaminated unitized wheel.
