3M 7010330787 Unitized Abrasive Wheel 4 Inch Ao

Product Description

The 3M 7010330787 is an extra hard, non-woven unitized abrasive wheel designed for aggressive edge deburring and surface finishing on ferrous and non-ferrous metals. Built on a 900 Series construction, this wheel uses aluminum oxide mineral bonded into a dense, compressed fiber matrix that delivers consistent cut rate and finish throughout the wheel's life. At 4 inches in diameter, it mounts via a standard unitized wheel mandrel (sold separately) and is compatible with common bench-mounted and portable rotary tools. Metalworkers, fabricators, and finishing technicians use this wheel when standard abrasive discs lack the edge durability needed for hard metals or stubborn burrs.

This wheel is well suited for deburring, blending, and light polishing operations on aluminum, steel, stainless steel, and other hard metals. Its extra hard density makes it particularly effective in production environments where extended wheel life and consistent material removal on heavy-duty parts are required. The wheel runs in both clockwise and counterclockwise directions, giving operators flexibility when pairing it with different machine configurations or tool orientations. Typical applications include weld seam blending, edge finishing after cutting or stamping, and surface prep before coating or inspection.

Key Features

• Extra hard density construction delivers aggressive deburring and edge finishing on hard metals
• Aluminum oxide mineral suited for ferrous and non-ferrous metals, including aluminum and stainless steel
• Runs clockwise and counterclockwise for greater versatility across tool types
• Non-woven fiber matrix maintains consistent cut and finish as the wheel wears
• Center-hole design attaches via a standard unitized wheel mandrel (sold separately)
• 900 Series construction offers increased edge durability over lower-density unitized wheel grades

Compatibility

Designed for use with standard unitized wheel mandrels on bench grinders, die grinders, and similar rotary tools that accept center-hole mounted abrasive wheels.

Installation Notes

Installation should be performed by qualified metalworking or fabrication personnel. Power down and disconnect the tool from its power source before mounting or removing the wheel. Confirm the tool spindle speed does not exceed the maximum rated RPM marked on the wheel or packaging before operation. A proper unitized wheel mandrel is required and is sold separately.
