3M 7010328890 Scotch-brite Exl Unitized Wheel 14 in Ao

Product Description

The 3M 7010328890 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. The unitized construction bonds abrasive fibers throughout the wheel body, delivering consistent cut and finish as the wheel wears. At 14 inches in diameter with a 1.25 inch arbor bore, this wheel mounts to bench grinders, pedestal grinders, and automated finishing equipment. Aluminum oxide abrasive provides reliable cutting action across a broad range of substrate hardness. The wheel weighs 1.75 pounds and measures approximately 14.5 inches in its packaged footprint.

This wheel is suited for industrial metalworking, fabrication shops, and automated robotic finishing lines where consistent edge treatment is required. Typical applications include deburring stamped or machined metal parts, blending weld seams, and final surface prep before coating or plating. Its conformable structure allows the abrasive to follow contoured and complex-shaped workpieces, making it useful for both flat stock and formed components. It is installed by machinists, fabricators, and surface finishing technicians in light manufacturing and heavy fabrication environments.

Key Features

• Unitized layered construction operates in clockwise or counterclockwise rotation
• Conformable abrasive body maintains contact with complex and contoured part geometries
• Resists smearing, producing cleaner surfaces with less secondary prep work
• Minimizes heat buildup, reducing thermal impact on heat-sensitive materials
• Wheel edge can be dressed for precision deburring, finishing, and polishing
• Suitable for metal alloys, many plastics, and composite materials

Compatibility

Designed for use on bench grinders, pedestal grinders, and automated finishing machines accepting a 1.25 inch arbor and accommodating a 14 inch diameter wheel.

Installation Notes

Installation should be performed by a qualified machinist or finishing technician following the equipment manufacturer's mounting instructions. Always power down and lock out the grinder before mounting or removing the wheel. Verify that the machine's rated speed meets or exceeds the wheel's maximum operating RPM before starting. Inspect the wheel for damage before each use and do not use a wheel that shows cracks, delamination, or uneven wear.
