3M 7010330305 Unitized Abrasive Wheel 2 Inch Ao 1/4 Inch Arbor

Product Description

The 3M 7010330305 is a unitized abrasive wheel from the Standard Abrasives 700 Series, designed for deburring, cleaning, and surface conditioning on metal workpieces. Built with aluminum oxide mineral on an open web construction, the wheel carries a medium to hard density that delivers consistent cut and longer service life under heavy use. At 2 inches in diameter with a 1/4 inch arbor hole, it mounts to a unitized wheel mandrel (sold separately) and runs in both clockwise and counterclockwise directions, making it adaptable to a range of tools and machines. Machinists, fabricators, and metal finishing tradespeople are the primary users of this wheel.

This wheel is suited for mid-sequence and finishing-sequence metalworking tasks in fabrication shops and manufacturing environments. Common applications include removing punched hole burrs on stainless steel, eliminating heavy flashing, smoothing medium-sized pits and scratches, and cleaning heavy scale or weld discoloration from ferrous and non-ferrous metals including aluminum. The 700 Series construction offers harder material density and greater edge durability compared to 600 Series unitized wheels, making it the appropriate choice where softer wheels wear prematurely or load up.

Key Features

• Medium to hard density aluminum oxide construction suits heavy deburring and hard metal cleaning
• Open web design resists loading, extending abrasive service life in scale and weld discoloration removal
• Runs clockwise and counterclockwise for greater tool and machine compatibility
• Harder density and increased edge durability compared to 600 Series unitized wheels
• Aluminum oxide mineral works on ferrous and non-ferrous metals including aluminum and stainless steel
• 1/4 inch arbor hole accepts standard unitized wheel mandrels (mandrel sold separately)

Compatibility

Designed for use with unitized wheel mandrels sized for a 1/4 inch arbor. Compatible with die grinders, bench grinders, and rotary tools that accept the appropriate mandrel attachment. No specific machine model compatibility was stated in the product data.

Installation Notes

Installation should be performed by qualified metal finishing or fabrication personnel familiar with abrasive wheel safety. Always power down and disconnect the tool before mounting or removing the wheel. Verify that the tool spindle speed does not exceed the rated maximum RPM of the wheel before operation. Wear appropriate PPE including eye protection and gloves when operating rotary abrasive tools.
