3M 7010330321 Unitized Abrasive Wheel 4 in Ao 1/4 in Arbor

Product Description

The 3M 7010330321 is an aluminum oxide unitized abrasive wheel from the 800 Series Standard Abrasives line. It is a high-density, hard-construction wheel built for heavy-duty edge deburring and surface polishing on ferrous and non-ferrous metals, including stainless steel and aluminum. The wheel measures 4 inches in diameter with a 1/4 inch center arbor hole and weighs 1.813 pounds. Its open-web construction resists loading, extending usable service life in demanding production and fabrication environments. Licensed HVAC, plumbing, and metalworking tradespeople who need consistent edge finishing will find this wheel suited to rotary tool and bench-mount applications.

This unitized wheel is designed for edge deburring, blending, and polishing operations on metal workpieces in industrial, fabrication, and maintenance settings. The aluminum oxide mineral performs well on carbon steel, stainless steel, and aluminum. Its hard density makes it a step up from 700 Series unitized wheels when tasks require increased edge durability and longer wheel life under continuous use. The wheel runs in both clockwise and counterclockwise directions, giving it added versatility across different tool and machine configurations.

Key Features

• High-density, hard-construction aluminum oxide wheel engineered for heavy-duty edge deburring and stainless steel polishing
• Open-web structure resists loading for extended abrasive service life
• Compatible with both clockwise and counterclockwise rotation for greater tool versatility
• Aluminum oxide mineral suits ferrous and non-ferrous metals including aluminum and stainless steel
• Hard density and extra-tough edge durability exceed the performance of 700 Series unitized wheels
• Attaches to rotary tools via a unitized wheel mandrel (sold separately)

Compatibility

Designed for use with rotary tools and machines that accept a 1/4 inch arbor-mount unitized wheel mandrel. Mandrel sold separately. Suitable for metal fabrication, maintenance, and finishing operations requiring a 4 inch diameter unitized wheel.

Installation Notes

Installation and mounting should be performed by qualified personnel familiar with abrasive wheel safety requirements per ANSI B7.1 standards. Ensure the tool or machine is powered down and fully de-energized before mounting or removing the wheel. Confirm the tool spindle speed rating meets or exceeds the maximum RPM rating of the wheel before use. Use only a compatible unitized wheel mandrel sized for the 1/4 inch arbor hole.
