3M 7000045935 Scotch-brite Unitized Wheel 3 in Ao

Product Description

The 3M 7000045935 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and finishing operations on metal alloys, plastics, and composites. Built with a soft, conformable, layered construction, this wheel maintains consistent abrasive contact across complex part geometries. The aluminum oxide abrasive mineral provides reliable cut and finish performance across a range of densities and grades. At 3 inches in diameter with a 1/4 inch arbor, it mounts directly to standard die grinders, bench grinders, and robotic finishing spindles. Weighing 0.054 pounds, it is lightweight and suited for both manual and automated applications.

This unitized wheel is used in metal fabrication, aerospace component finishing, and general industrial maintenance wherever controlled deburring and surface conditioning are required. It performs on ferrous and non-ferrous metal alloys as well as many plastics and composites. The conformable consistency makes it effective on contoured, curved, or complex-shaped workpieces where rigid abrasive wheels lose contact. It is appropriate for both bench-mounted and handheld rotary tool setups.

Key Features

• Soft, conformable layered construction maintains abrasive contact on complex and contoured part shapes
• Operates in clockwise or counterclockwise rotation — suitable for bidirectional tooling setups
• Minimizes heat buildup, reducing thermal impact on heat-sensitive base materials
• Resists smearing for cleaner cut surfaces and reduced prep time between operations
• Wheel edge can be dressed to restore profile for continued deburring, finishing, and polishing
• Available across multiple density grades from soft and conformable to hard and aggressive for varied application demands

Compatibility

Designed as an OEM-style unitized abrasive wheel for use with standard 1/4 inch arbor rotary tools, die grinders, and automated finishing equipment handling metal alloys, plastics, and composites.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using standard rotary or bench grinding equipment. Always power down and de-energize the tool before mounting or removing the wheel. Verify that the tool RPM rating meets or exceeds the wheel speed rating before operation. Inspect the wheel for damage prior to each use and ensure the arbor nut is properly secured before starting the tool.
