3M 7000120752 Scotch-brite Exl Unitized Wheel 0.5 in

Product Description

The 3M 7000120752 is a Scotch-Brite EXL Unitized Abrasive Wheel designed for smoothing, deburring, and finishing metal alloys, plastics, and composites. The wheel measures 0.5 inches in diameter and weighs approximately 0.01 pounds. Its soft, conformable construction keeps the abrasive in consistent contact with workpiece surfaces, including complex geometries. Silicon carbide abrasive grain provides effective cut while resisting heat buildup, making it suitable for use on heat-sensitive materials. Unitized wheels in this line are available in a range of densities, from a soft 2 density for high conformability to a hard 8 density for aggressive cut and durability.

This unitized wheel is suited for precision deburring, edge finishing, and surface preparation across a wide range of industrial and fabrication applications. It performs on metal alloys including stainless and aluminum, as well as many plastics and composites. The wheel is compatible with automated robotic processing setups where consistent abrasive contact with complex part profiles is required. It is also used in manual bench or handheld spindle applications where controlled surface finishing is needed without smearing or excessive heat generation.

Key Features

• Silicon carbide abrasive grain delivers consistent cut on metals, plastics, and composites
• Soft, conformable construction maintains abrasive contact on complex-shaped parts
• Unitized layered construction supports both clockwise and counterclockwise operation
• Resists smearing for cleaner surface results and reduced prep time
• Minimizes heat buildup, reducing impact on heat-sensitive materials
• Wheel edge can be dressed for deburring, finishing, and polishing applications

Compatibility

Designed for use on metal alloys, plastics, and composites in bench spindle, handheld rotary tool, and robotic processing applications where a small-diameter unitized abrasive wheel is required.

Installation Notes

This wheel is installed by fabricators and finishing technicians on compatible spindle or rotary tool arbors. Verify spindle speed rating does not exceed the wheel manufacturer maximum RPM before mounting. Ensure the wheel is properly secured to the arbor and all guarding is in place before operation. Inspect the wheel for damage before each use and replace if cracking or delamination is present.
