3M 7000000721 Scotch-brite Exl Unitized Wheel 2 Inch Fine Grit

Product Description

The 3M 7000000721 is a Scotch-Brite EXL Unitized Wheel designed for deburring, smoothing, and surface finishing on metal alloys, plastics, and composites. Built with a soft, conformable construction and silicon carbide abrasive at a fine grit rating, this wheel removes burrs and refines edges without smearing or loading. The layered unitized structure maintains consistent cut and finish performance throughout the wheel's life. It is used by metalworkers, fabricators, and finishing technicians on bench grinders, die grinders, and automated robotic processing equipment.

This wheel is suited for production and job-shop environments where edge finishing, light deburring, and surface prep are required on a range of substrates. Its fine grit and soft density make it appropriate for applications where conformability matters, such as contoured or complex-shaped parts. The wheel minimizes heat build-up, reducing the risk of thermal distortion on heat-sensitive materials including certain plastics and light alloys.

Key Features

• Silicon carbide abrasive with fine grit for controlled deburring and finishing
• Soft, conformable unitized construction conforms to complex and irregular part geometries
• Operates clockwise or counterclockwise for flexible machine compatibility
• Resists smearing for cleaner finished surfaces with less prep work
• Minimizes heat build-up to protect heat-sensitive materials during processing
• Wheel edge can be dressed to maintain cutting performance over time

Compatibility

Designed for use on metal alloys, plastics, and composites; compatible with bench grinders, die grinders, and robotic finishing systems that accept 2-inch unitized wheels.

Installation Notes

Installation should be performed by a qualified metalworking or maintenance technician following the machine manufacturer's mounting guidelines. Ensure the grinder or spindle is powered down and fully stopped before mounting or removing the wheel. Verify that the machine's rated RPM does not exceed the wheel's maximum operating speed before use. Eye protection and appropriate PPE are required during operation.
