3M 7000045931 Scotch-brite Exl Unitized Wheel 6 in Ao

Product Description

The 3M 7000045931 is a Scotch-Brite EXL Unitized Abrasive Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. Its soft, conformable construction allows the abrasive mineral to maintain consistent contact across irregular and complex part geometries. The wheel measures 6 inches in diameter with a 1/2 inch arbor and weighs 0.46 pounds. Aluminum oxide (AO) abrasive mineral provides reliable cut and durability across a wide range of workpiece materials. This wheel is used by machinists, fabricators, and finishing technicians working in both manual and automated production environments.

This unitized wheel is suited for edge finishing, deburring, and surface prep on metal alloys including steel, stainless, and aluminum, as well as many plastics and composites. Its layered, unitized construction allows operation in both clockwise and counterclockwise directions, making it compatible with standard bench grinders, right-angle grinders, and robotic finishing cells. It is a practical choice for production environments where consistent surface quality and minimal heat generation are priorities.

Key Features

• Soft, conformable construction keeps abrasive in contact with complex and irregular part shapes
• Bidirectional operation — runs clockwise or counterclockwise without performance loss
• Minimizes heat buildup, reducing risk of thermal damage to heat-sensitive materials
• Resists smearing for cleaner surface results and reduced prep time between operations
• Wheel edge can be dressed to maintain effective cut geometry for deburring and polishing
• Layered, unitized build provides consistent performance throughout the life of the wheel

Compatibility

Designed for use on metal alloys, plastics, and composites; fits standard bench grinder and right-angle grinder arbors accepting a 1/2 inch arbor hole with a 6 inch diameter wheel.

Installation Notes

Installation should be performed by qualified shop personnel following the grinder or spindle manufacturer's mounting instructions. Always power down and de-energize the machine before mounting or removing the wheel. Verify that the machine's maximum RPM rating meets or exceeds the wheel's rated speed before operation. Inspect the wheel for damage before each use and discard any wheel that shows cracking, fraying, or deformation.
