3M 7000120680 Scotch-brite Exl Unitized Wheel 2 in 1/4 in Arbor

Product Description

The 3M 7000120680 is a Scotch-Brite EXL Unitized Abrasive Wheel designed for smoothing, deburring, and finishing operations on metal alloys, plastics, and composites. Built with a soft, conformable construction, the wheel maintains consistent abrasive contact across irregular and complex part geometries. At 2 inches in diameter with a 1/4-inch arbor, it mounts easily on standard die grinders and bench-mounted spindles. The unitized layered structure allows the wheel to run in either clockwise or counterclockwise rotation, giving it flexibility across a range of finishing setups. Aluminum oxide abrasive provides reliable cut without excessive heat buildup, making it suitable for heat-sensitive base materials.

This wheel is well suited for bench finishing, robotic processing cells, and hand-held die grinder applications in metal fabrication, aerospace component finishing, and general manufacturing. It handles edge deburring, light surface blending, and pre-polish preparation on stainless steel, aluminum, titanium, and many engineered plastics and composites. The wheel edge can be dressed to maintain a consistent profile for repeatable results on production runs. Technicians and machinists working on tight-tolerance parts will find the conformable density particularly useful for maintaining finish consistency without aggressive stock removal.

Key Features

• Soft, conformable unitized construction maintains abrasive contact on complex and irregular part geometries
• Runs clockwise or counterclockwise, adding flexibility to existing spindle and grinder setups
• Minimizes heat buildup, reducing risk of thermal damage on heat-sensitive metals and plastics
• Resists smearing for cleaner surface results and reduced prep time between operations
• Wheel edge is dressable for consistent deburring, finishing, and polishing profiles
• Compatible with robotic processing applications due to consistent conformability under programmed pressure

Compatibility

Designed as an OEM-style replacement and standard consumable for die grinders and bench spindles accepting a 1/4-inch arbor. Suitable for use on metal alloys, many plastics, and composite materials.

Installation Notes

Installation is performed by machinists, toolroom technicians, or finishing specialists using standard die grinder or spindle equipment. Ensure the spindle is fully powered down and locked out before mounting or removing the wheel. Verify that the tool RPM rating meets or exceeds the wheel speed rating before operation. Dress the wheel edge as needed prior to first use to establish the desired contact profile.
