3M 7000046912 Unitized Abrasive Wheel 3 in Ao 1/4 in Arbor

Product Description

The 3M 7000046912 is a 3 inch diameter unitized abrasive wheel built for mid-sequence metalworking operations including deburring, cleaning, and surface conditioning. It uses aluminum oxide mineral bonded in a medium-to-hard density open web construction. The 1/4 inch arbor center hole mounts to a compatible unitized wheel mandrel, sold separately. Licensed metalworkers and fabricators use this wheel on bench grinders, die grinders, and similar rotary equipment. The harder density and increased edge durability place it above 600 Series unitized wheels for heavier-duty tasks where longer service life matters.

This wheel is suited for ferrous and non-ferrous metal applications including stainless steel and aluminum. Common tasks include removing punched hole burrs, cleaning heavy scale, removing weld discoloration, and addressing medium-sized pits and scratches. The open web structure resists loading, which extends usable wheel life in production or field service environments. Metal fabricators, maintenance technicians, and tool-and-die professionals are the primary installers and operators of this product.

Key Features

• Medium-to-hard density aluminum oxide construction suited for mid-sequence deburring and hard metal cleaning
• Increased edge durability over 600 Series unitized wheels for heavier-duty applications
• Open web design resists loading and extends abrasive service life
• Runs clockwise and counterclockwise for greater tool and machine compatibility
• Aluminum oxide mineral works on both ferrous and non-ferrous metals including aluminum
• 1/4 inch arbor center hole accepts a standard unitized wheel mandrel

Compatibility

Designed for use with rotary tools and machines that accept a unitized wheel mandrel with a 1/4 inch arbor. Mandrel sold separately.

Installation Notes

Installation and operation should be performed by qualified personnel familiar with abrasive wheel safety standards, including ANSI B7.1 guidelines. Always power down and disconnect the tool before mounting or changing the wheel. Inspect the wheel for cracks or damage before each use and confirm the tool spindle speed does not exceed the wheel maximum rated speed. Wear appropriate eye protection and guarding during operation.
