3M 7010328940 Scotch-brite Exl Unitized Wheel 2 in Ao

Product Description

The 3M 7010328940 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. The wheel uses an aluminum oxide (AO) abrasive in a layered, unitized construction that maintains a soft, conformable consistency throughout the life of the product. At 2 inches in diameter with a 0.188 inch arbor, it mounts on standard bench grinders, die grinders, and automated finishing equipment. Machinists, fabricators, and finishing technicians install this wheel where controlled material removal and surface prep are required without aggressive heat generation.

This wheel is suited to light industrial and production finishing environments, including deburring of stamped or machined metal parts, edge finishing on sheet metal, and surface conditioning of plastics and composites. Its conformable build makes it well matched to robotic and automated processing lines where consistent contact with complex-shaped workpieces is critical. Manual bench and die grinder applications are equally common.

Key Features

• Unitized layered construction allows operation in both clockwise and counterclockwise directions
• Soft, conformable consistency maintains abrasive contact on complex or irregular part geometries
• Wheel edge can be dressed for targeted deburring, finishing, and polishing work
• Resists smearing for cleaner finished surfaces with less secondary prep required
• Minimizes heat build-up, reducing risk of damage to heat-sensitive base materials
• Aluminum oxide abrasive provides consistent cut on a wide range of metal alloys, plastics, and composites

Compatibility

Designed for use on metal alloys, plastics, and composites. Compatible with bench grinders, die grinders, and robotic finishing equipment accepting a 0.188 inch arbor and 2 inch diameter wheel.

Installation Notes

Installation is typically performed by machinists or finishing equipment operators. Always power down and disconnect the grinder or finishing tool before mounting or changing wheels. Confirm arbor size and maximum RPM rating of the machine matches the wheel specifications before operation. Inspect the wheel for damage before each use and do not exceed the rated speed.
