3M 7000120908 Scotch-brite Convolute Deburring Wheel 12 Inch

Product Description

The 3M 7000120908 is a convolute-constructed, non-woven abrasive wheel designed for light deburring, polishing, and surface finishing on metal, composite, and glass workpieces. The soft convolute build runs cool and smooth, reducing operator fatigue compared to harder wheel constructions. A unique resin system minimizes smearing, which cuts down on part prep and cleanup time between operations. The non-woven web continuously exposes fresh abrasive mineral as the wheel wears, delivering consistent cut and finish throughout the wheel's service life. Measuring 12 inches in diameter and 1.69 inches in face width, this wheel fits standard arbor-mounted finishing setups used in fabrication and machine shop environments.

This wheel is suited for light deburring, blending, polishing, and cleaning operations across a range of materials including ferrous and non-ferrous metals, composites, and glass. It is commonly used in metal fabrication shops, aerospace component finishing, and general manufacturing where heat-sensitive materials require a cool-running abrasive. The convolute construction conforms to irregular surfaces, making it effective for finishing contoured or machined parts. Technicians and machinists installing this wheel should verify spindle speed compatibility and arbor bore fit before mounting.

Key Features

• Convolute non-woven construction runs cool, reducing heat buildup on heat-sensitive workpieces
• Continuously exposes fresh abrasive mineral for consistent cut rate and finish throughout wheel life
• Soft construction conforms to surface irregularities for uniform finishing results
• Unique resin system reduces smearing, minimizing cleanup and prep time between operations
• Multi-purpose wheel handles deburring, blending, polishing, and cleaning in a single tool
• Compatible with metals, composites, and glass surfaces

Compatibility

Designed for use on standard arbor-mounted bench or pedestal grinders and finishing machines that accept convolute-style non-woven abrasive wheels. Verify arbor bore diameter and maximum rated spindle speed before mounting.

Installation Notes

Installation should be performed by a qualified machinist or fabrication technician. Power down and lock out the machine before mounting or removing the wheel. Confirm that the machine spindle speed does not exceed the wheel's rated maximum RPM, and use the correct flanges and hardware for secure mounting. Inspect the wheel for damage before each use and do not operate a cracked or compromised wheel.
