3M 7100066551 Scotch-brite EX2 Convolute Deburring Wheel 6 in

Product Description

The 3M 7100066551 is a convolute-constructed deburring wheel in the Scotch-Brite EX2 series, designed for mid-range aggressiveness and hardness across a broad set of surface-finishing operations. This wheel handles deburring, edge radiusing, blending, polishing, and finishing on metal alloys, many plastics, and composites. At 6.9 inches in diameter and 4.4 inches wide, it is sized for bench grinder and stationary finishing machine setups. Weighing 0.8 pounds, it is straightforward to mount and change out during production runs. The wheel performs best when presented consistently with sharp edges or metal burrs.

This deburring wheel is used in metal fabrication, machine shops, and industrial finishing environments where consistent surface quality is required. It suits applications involving all common metal alloys as well as select plastics and composites. The layered construction supports both clockwise and counterclockwise spindle rotation, making it adaptable to a range of bench-mounted finishing equipment. Fabricators, machinists, and industrial maintenance technicians typically use this wheel for production deburring and final surface prep work before inspection or assembly.

Key Features

• Convolute construction delivers mid-range hardness and aggressiveness suitable for deburring, blending, and polishing
• Wheel edge can be dressed to maintain effective cutting action on all metal alloys and many plastics and composites
• Operates in clockwise or counterclockwise rotation for flexible machine compatibility
• Resists smearing, resulting in cleaner surfaces and reduced prep time
• Minimizes heat buildup, reducing risk of thermal damage on heat-sensitive materials
• Tough, layered unitized construction supports extended service life in production environments

Compatibility

Designed for use on bench grinders and stationary finishing machines that accept convolute deburring wheels. Suitable for deburring and finishing operations on all common metal alloys and many plastics and composites.

Installation Notes

Installation is typically performed by a machinist or maintenance technician. Power down and lock out the finishing machine before mounting or removing the wheel. Verify that the machine spindle speed rating does not exceed the maximum RPM rating of the wheel before operation. Dress the wheel edge as needed using appropriate dressing tools to maintain cutting performance.
