3M 7000120788 Deburring Wheel 3 Inch Aluminum Oxide

Product Description

The 3M 7000120788 is an aluminum oxide unitized deburring wheel rated for metal finishing and surface conditioning applications. With a density rating of 7 and a hard grade designation, this wheel delivers consistent cutting action while maintaining its shape under sustained load. It measures 3 inches in diameter with a 1/8 inch face width and mounts on a 3/8 inch center hole arbor. The 18,100 RPM maximum speed rating makes it compatible with high-speed rotary tooling used in fabrication and metalworking environments. Licensed tradespeople and shop technicians working on burr removal, edge blending, and light stock removal tasks will find this wheel well-suited to production and bench applications.

This deburring wheel is designed for use on centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. Its unitized construction bonds the abrasive material throughout the wheel body rather than only on the surface, which provides a more even cut and extended service life compared to surface-only abrasive products. Typical applications include deburring cut tube, pipe ends, machined castings, and stamped metal parts in light industrial and fabrication settings.

Key Features

• Aluminum oxide abrasive for reliable performance on ferrous and non-ferrous metals
• Density 7, hard grade construction for consistent cut-rate under sustained contact pressure
• Unitized wheel design distributes abrasive throughout the body for extended, even wear
• 18,100 RPM maximum speed rating suits high-speed die grinders and inline sanders
• 3/8 inch center hole fits standard mandrels used across common rotary tooling platforms
• Compatible with multiple tool types including centerless grinders and manual backstands

Compatibility

Compatible with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands accepting a 3/8 inch arbor and rated for wheels up to 18,100 RPM.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive wheel safety. Before mounting, verify that the tool spindle speed does not exceed the 18,100 RPM maximum rating marked on the wheel. Power down and disconnect the tool from its power source before changing wheels. Inspect the wheel for cracks or damage prior to each use and do not use if any damage is found; abrasive wheel standards per ANSI B7.1 apply.
