3M 7010309501 Scotch-brite Exl Unitized Wheel 8 in

Product Description

The 3M 7010309501 is a Scotch-Brite EXL Unitized Abrasive Wheel engineered for smoothing, deburring, and finishing operations on metal alloys, plastics, and composites. The wheel measures 8 inches in diameter with a 5/8 inch arbor bore and ships at 0.48 pounds. Its soft, conformable construction keeps the abrasive in consistent contact with irregular and complex part geometries, making it well-suited for both manual bench work and robotic or automated finishing lines. The unitized, layered structure resists loading and smearing, producing cleaner surfaces with less prep work between passes.

This wheel is designed for metalworking and fabrication environments where edge finishing, deburring, and surface conditioning are routine tasks. Typical applications include finishing cut edges on sheet metal, smoothing weld zones, and preparing surfaces on machined components prior to coating or assembly. The conformable construction is particularly effective on contoured or profiled workpieces where a rigid wheel would lose contact. It is used in production shops, fabrication facilities, and maintenance settings by machinists, fabricators, and tool-room technicians.

Key Features

• Soft, conformable construction maintains abrasive contact on complex and contoured part shapes
• Unitized, layered build allows operation in both clockwise and counterclockwise directions
• Resists smearing for cleaner finished surfaces and reduced prep between operations
• Minimizes heat build-up, protecting heat-sensitive base materials during finishing
• Wheel edge can be dressed to restore cutting action for deburring, finishing, and polishing
• Suitable for metal alloys, many plastics, and composite materials

Compatibility

Designed for use on bench grinders, angle grinders, and automated finishing equipment accepting a 5/8 inch arbor and an 8 inch diameter wheel. Suitable for ferrous and non-ferrous metal alloys, many plastics, and composites.

Installation Notes

Installation should be performed by a qualified operator following the machine manufacturer's safe operating speed rating — never exceed the maximum RPM marked on the wheel or the spindle. Ensure the machine is fully powered down and the spindle is locked before mounting or removing the wheel. Inspect the wheel for damage before each use and run it briefly behind a guard before bringing it into contact with the workpiece. Follow applicable ANSI B11 and OSHA 1910.215 grinding safety standards.
