3M 7010329220 Scotch-brite Exl Unitized Wheel 3 in Ao

Product Description

The 3M 7010329220 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. The wheel measures 3 inches in diameter and mounts on a 1/4-inch arbor, making it compatible with standard die grinders and bench-mounted spindles. Its aluminum oxide abrasive construction delivers consistent cut and finish across a range of material types. The unitized, layered design holds its shape throughout the life of the wheel, providing repeatable results from the first use to the last. This wheel weighs 0.11 pounds and is sold individually.

This wheel is suited for metalworking, fabrication, and finishing operations in industrial, commercial, and shop environments. Typical applications include edge deburring after cutting or stamping, blending weld seams, and final surface preparation before coating or inspection. The conformable consistency allows the abrasive to maintain contact with contoured or complex-shaped parts, making it a practical choice for both manual hand-tool use and robotic or automated finishing setups. Machinists, fabricators, and metal finishing technicians are the primary users of this wheel.

Key Features

• Soft, conformable construction keeps abrasive in contact with irregular and complex part geometries
• Layered unitized build operates in both clockwise and counterclockwise directions
• Resists smearing for cleaner cut surfaces and reduced prep time between operations
• Minimizes heat buildup, reducing thermal impact on heat-sensitive base materials
• Wheel edge can be dressed to maintain effective deburring and polishing performance
• Aluminum oxide abrasive suitable for metal alloys, many plastics, and composites

Compatibility

Designed for use with die grinders, bench grinders, and spindle-mounted finishing equipment accepting a 1/4-inch arbor.

Installation Notes

Installation is performed by qualified machinists or finishing technicians. Before mounting, power down and disconnect the tool from its power source. Confirm the tool spindle speed does not exceed the rated RPM of the wheel before operation. Inspect the wheel for damage prior to each use and replace if deformation or excessive wear is observed.
