3M 7000045948 Scotch-brite Exl Unitized Wheel 1.5 in

Product Description

The 3M 7000045948 is a Scotch-Brite EXL Unitized Abrasive Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. The wheel measures 1.5 inches in diameter and fits a 3/16-inch arbor, making it compatible with standard rotary tools and die grinders used in fabrication and finishing work. Its soft, conformable construction keeps the abrasive material in continuous contact with contoured or irregular part surfaces, including those processed in robotic or automated setups. The aluminum oxide abrasive media resists smearing and minimizes heat buildup, both critical when working heat-sensitive substrates.

This wheel is suited for bench-mounted rotary tools, portable die grinders, and automated robotic finishing cells in metal fabrication, aerospace component finishing, and general industrial maintenance applications. Technicians and fabricators use it for edge deburring, light surface conditioning, and pre-polish preparation on parts where surface integrity must be maintained. The unitized construction allows operation in both clockwise and counterclockwise directions, adding flexibility for varied tooling setups.

Key Features

• Soft, conformable construction maintains abrasive contact on complex-shaped and contoured parts
• Operates in clockwise or counterclockwise rotation for flexible tooling compatibility
• Resists smearing for cleaner surface finishes and reduced prep time
• Minimizes heat buildup, reducing risk of thermal damage to heat-sensitive materials
• Wheel edge can be dressed for targeted deburring, finishing, and polishing
• Suitable for metal alloys, many plastics, and composite materials

Compatibility

Designed as an OEM-style replacement and general-use unitized abrasive wheel for rotary tools and die grinders accepting a 3/16-inch arbor.

Installation Notes

Installation is typically performed by machinists, fabricators, or maintenance technicians using standard arbor-mount tooling. Ensure the rotary tool or die grinder is fully powered down and unplugged before mounting or removing the wheel. Verify that the tool spindle speed does not exceed the rated maximum RPM of the wheel before operating. Inspect the wheel for damage before each use and do not use a wheel that shows cracking or delamination.
