3M 7000120905 Convolute Deburring Wheel 12 Inch

Product Description

The 3M 7000120905 is a convolute-constructed light deburring wheel designed for deburring, polishing, and blending on metal, composite, and glass surfaces. Built with a soft, non-woven web construction, the wheel runs cool and requires less operator effort compared to harder wheel constructions. The non-woven abrasive structure continuously exposes fresh mineral during use, which supports consistent stock removal and a polished surface finish in a single operation. At 12 inches in diameter and approximately 3.9 inches in face width, this wheel fits bench grinder and pedestal grinder arbors used in fabrication and finishing shops.

This wheel is suited for light deburring and finishing tasks in metal fabrication, aerospace component prep, and general industrial finishing. Typical applications include removing fine burrs from machined edges, blending weld areas, and polishing finished surfaces on ferrous and non-ferrous metals, composites, and glass. The cool-running non-woven construction makes it appropriate for heat-sensitive materials where grinding heat could cause distortion or discoloration. It is sold as a single wheel and is intended for professional shop use.

Key Features

• Convolute non-woven construction runs cool and reduces heat buildup on sensitive materials
• Soft wheel construction lowers operator effort compared to harder abrasive wheels
• Continuously exposes fresh abrasive mineral for consistent finishing throughout wheel life
• Unique resin system reduces smearing, cutting clean-up and prep time between operations
• Multi-purpose: deburrs, polishes, blends, cleans, and finishes metals, composites, and glass
• 12-inch diameter with approximately 3.9-inch face width suits standard bench and pedestal grinder setups

Compatibility

Designed for use on bench grinders and pedestal grinders accepting convolute deburring wheels with a 12-inch diameter. Suitable for ferrous metals, non-ferrous metals, composites, and glass surfaces requiring light deburring or finishing.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B7.1 guidelines. Always power down and lock out the grinder before mounting or dismounting the wheel. Inspect the wheel for cracks or damage before each use and confirm the machine speed rating does not exceed the wheel speed rating. Use appropriate flanges and a blotter as required by the grinder manufacturer.
