3M 7010366269 Scotch-brite Exl Unitized Wheel 4 in Ao

Product Description

The 3M 7010366269 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and finishing metal alloys, plastics, and composites. The wheel measures 4 inches in diameter with a 3/8-inch arbor bore and is constructed from aluminum oxide (AO) abrasive mineral bonded in a soft, conformable, layered unitized structure. This wheel type is used on bench grinders, die grinders, and automated robotic finishing systems. Metalworkers, fabricators, and finishing technicians use these wheels when edge quality, surface consistency, and heat control are priorities on production or job-shop work.

This wheel suits applications where controlled deburring and surface finishing are required on metal alloys, plastics, and composite materials. Its conformable construction allows the abrasive to maintain contact with contoured and complex-shaped parts, making it well suited for both manual bench operations and automated robotic processing lines. The unitized design supports use in either clockwise or counterclockwise rotation, adding flexibility across different machine setups and production configurations.

Key Features

• Conformable, layered unitized construction maintains abrasive contact on complex and contoured part geometries
• Aluminum oxide (AO) abrasive mineral for consistent cutting action on metal alloys and many plastics and composites
• Operates in both clockwise and counterclockwise rotation directions
• Minimizes heat build-up to reduce thermal impact on heat-sensitive base materials
• Resists smearing for cleaner finished surfaces and reduced prep between passes
• Wheel edge can be dressed for targeted deburring, finishing, and polishing

Compatibility

Designed as a unitized abrasive wheel for use on bench grinders and die grinders accepting a 3/8-inch arbor bore, as well as automated robotic finishing equipment configured for 4-inch diameter wheel tooling.

Installation Notes

Installation and mounting should be performed by a qualified metalworking or finishing technician familiar with abrasive wheel safety standards. Always power down and de-energize the grinder or finishing machine before mounting or removing the wheel. Verify that the machine spindle speed does not exceed the maximum rated speed marked on the wheel. Inspect the wheel for visible damage before each use and never operate a cracked or compromised wheel.
