3M 7010330789 Unitized Abrasive Wheel 12 Inch Aluminum Oxide

Product Description

The 3M 7010330789 is a 12-inch diameter unitized abrasive wheel built for aggressive edge deburring and surface finishing on hard metals. Part of the 900 Series, it carries the highest density rating in the Standard Abrasives Unitized Wheels line. The non-woven construction uses aluminum oxide mineral bonded at an extra hard density, delivering the toughness and edge durability needed to remove stubborn burrs and polish ferrous and non-ferrous metals efficiently. At 2 pounds, the wheel is substantial enough for sustained heavy-duty machine work. Licensed tradespeople and metalworking professionals are the primary installers and users of this product.

This wheel is suited for heavy-duty deburring, blending, and finishing applications on ferrous metals, non-ferrous metals, and aluminum. The extra hard density and coarse-to-medium mineral grade make it appropriate for production-level tasks where softer wheels wear out too quickly. It is designed for use with power tools and machines that accept a center-hole unitized wheel mounted via a unitized wheel mandrel, which is sold separately. The wheel runs in both clockwise and counterclockwise directions, providing flexibility across different tool configurations and machine setups.

Key Features

• Extra hard density with medium and coarse aluminum oxide mineral for aggressive edge deburring
• Higher material density and edge durability compared to 800 Series Unitized Wheels, extending wheel life on heavy-duty tasks
• Non-woven aluminum oxide construction is compatible with ferrous and non-ferrous metals, including aluminum
• Bidirectional operation — runs clockwise and counterclockwise — for versatility across tool and machine pairings
• Center-hole design mounts via a unitized wheel mandrel (sold separately)

Compatibility

Designed for use with power tools and machines that accept a center-hole unitized wheel mounted with a compatible unitized wheel mandrel. Offers improved performance and longevity over 800 Series Unitized Wheels for heavy-duty ferrous and non-ferrous metal applications.

Installation Notes

Mounting and operation should be performed by qualified personnel following applicable machine-guarding and abrasive-wheel safety standards. Always power down and de-energize the tool or machine before mounting or removing the wheel. Confirm the tool spindle speed does not exceed the rated maximum RPM of the wheel before operation. A compatible unitized wheel mandrel is required and is not included with this wheel.
