3M 7000121904 Unitized Abrasive Wheel 2 in Ao 1/8 in Arbor

Product Description

The 3M 7000121904 is a 2-inch diameter unitized abrasive wheel built for deburring, cleaning, and surface conditioning on metalworking applications. It uses aluminum oxide mineral bonded in a medium-to-hard density open web construction, which resists loading and extends service life under sustained use. The 1/8-inch arbor hole attaches to a compatible unitized wheel mandrel, sold separately. This wheel is suited for mid-sequence and finishing tasks where consistent material removal and edge durability are required. Licensed trades and metalworking professionals working with ferrous and non-ferrous metals will find this wheel a reliable production consumable.

This wheel is designed for tough deburring and cleaning tasks including removal of punched-hole burrs on stainless steel, elimination of heavy flashing, and cleaning of heavy scale or weld discoloration. The aluminum oxide abrasive performs on both ferrous and non-ferrous metals, including aluminum. The 700 Series construction offers harder density and increased edge durability compared to 600 Series unitized wheels, making it a step up for heavier-duty mid-sequence work in fabrication and finishing environments.

Key Features

• Medium-to-hard density aluminum oxide construction suited for mid-sequence deburring and hard-metal cleaning
• Open web design resists loading, extending abrasive service life in sustained use
• Runs clockwise and counterclockwise for greater flexibility with various tools and machines
• Increased edge durability over 600 Series unitized wheels for heavier-duty applications
• Compatible with ferrous and non-ferrous metals, including aluminum and stainless steel
• 1/8-inch arbor hole attaches via unitized wheel mandrel, sold separately

Compatibility

Designed for use with standard unitized wheel mandrels accepting a 1/8-inch arbor; suitable for die grinders, bench grinders, and other compatible rotary tools used in metal fabrication and finishing.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B7.1 guidelines. Always power down and disconnect the tool before mounting or removing the wheel. Confirm the tool RPM rating meets or exceeds the wheel RPM rating before operation. Inspect the wheel for damage before each use and do not use damaged or deformed wheels.
