3M 7000120748 Scotch-brite Exl Unitized Wheel 8 in Fine

Product Description

The 3M 7000120748 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. The wheel measures 8 inches in diameter and uses silicon carbide abrasive at a fine grit rating. Its soft, conformable construction keeps the abrasive in consistent contact with the workpiece, including complex contours and edges. The layered, unitized build delivers controlled cut without loading or smearing, making it a dependable choice for fabricators, metalworkers, and finishing technicians who need repeatable surface results.

This wheel is suited for deburring, blending, and finish work on fabricated metal components in both production and job-shop environments. The silicon carbide abrasive cuts cleanly on ferrous and non-ferrous metals as well as many plastics and composites. Its conformable density makes it well-suited for robotic and automated finishing applications where the wheel must follow irregular or complex part geometries. It can be dressed at the edge for targeted deburring and edge-finishing passes.

Key Features

• Silicon carbide abrasive at fine grit for controlled smoothing and edge finishing
• Soft, conformable construction maintains contact on complex-shaped and contoured parts
• Layered, unitized structure operates in clockwise or counterclockwise rotation
• Resists smearing and loading for cleaner surfaces with less prep work
• Minimizes heat buildup, reducing thermal impact on heat-sensitive materials
• Wheel edge can be dressed for precision deburring and polishing passes

Compatibility

Designed for use on metal alloys, plastics, and composites requiring deburring, blending, or surface finishing; suitable for bench-mounted, pedestal, or automated robotic finishing equipment that accepts unitized wheel arbor configurations.

Installation Notes

Installation should be performed by a qualified metalworking or grinding equipment operator following the machine manufacturer's mounting guidelines. Power down and lock out the grinder or finishing machine before mounting or removing the wheel. Confirm that the spindle speed rating of the machine does not exceed the wheel's rated maximum RPM. Wear appropriate PPE including eye protection and gloves during mounting and operation.
