3M 7010310379 Unitized Abrasive Wheel 6 in Aluminum Oxide

Product Description

The 3M 7010310379 is an aluminum oxide unitized abrasive wheel built for heavy-duty edge deburring and surface finishing on metal. Part of the 800 Series, it features a hard density construction that delivers extra edge durability compared to lower-series unitized wheels. The open web design resists loading, extending abrasive service life during sustained use. At 6 inches in diameter with a 7/8 inch arbor, this wheel mounts to standard angle grinders and bench-mounted unitized wheel mandrels. It is suited for use by machinists, fabricators, and metalworking professionals who require consistent edge work on ferrous and non-ferrous metals.

This wheel is designed for edge deburring, blending, and polishing applications on stainless steel, carbon steel, aluminum, and other metals. The 800 Series hard density rating makes it a strong fit for aggressive deburring passes where a softer wheel would wear prematurely. The wheel runs both clockwise and counterclockwise, adding flexibility when pairing it with a variety of power tools and automated machines. Typical applications include weld seam cleanup, part edge finishing after sawing or punching, and pre-inspection surface preparation in fabrication and manufacturing environments.

Key Features

• Hard density 800 Series construction for extended life on heavy-duty edge deburring tasks
• Aluminum oxide mineral works on ferrous and non-ferrous metals including stainless steel and aluminum
• Open web resists loading and contributes to longer abrasive service life
• Runs clockwise and counterclockwise for compatibility with a wide range of tools and machines
• 6 inch diameter with 7/8 inch arbor for standard mandrel mounting

Compatibility

Designed for use with unitized wheel mandrels sold separately. Center hole arbor configuration is compatible with standard angle grinders and bench-mounted spindle setups that accept a 7/8 inch arbor.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety practices. Always power down and de-energize the tool before mounting or removing the wheel. Verify the tool spindle speed does not exceed the maximum rated RPM marked on the wheel before operation. A unitized wheel mandrel, sold separately, is required for proper mounting to handheld or stationary equipment.
