3M 7000046921 Unitized Abrasive Wheel 6 Inch Aluminum Oxide

Product Description

The 3M 7000046921 is an aluminum oxide 800 Series unitized abrasive wheel built for heavy-duty edge deburring and stainless steel polishing. It features a hard density construction that delivers extra edge durability, making it suited for demanding metalworking tasks where a softer wheel would wear prematurely. At 6 inches in diameter with a 1 inch arbor, it mounts to standard angle grinders and bench tools using a unitized wheel mandrel sold separately. The open web design resists loading, which extends abrasive service life in continuous production or service environments. Licensed HVAC techs, machinists, fabricators, and metalworkers are the primary installers and operators of this wheel.

This wheel is used across ferrous and non-ferrous metal applications, including steel, stainless steel, and aluminum. The 800 Series hard density compound with aluminum oxide mineral performs well on edge work, blending, and light surface conditioning. It runs in both clockwise and counterclockwise directions, giving operators flexibility when pairing it with different machines or handheld tools. Typical applications include production deburring, weld blending, and finishing operations in fabrication shops or field metalwork settings.

Key Features

• Hard density wheel construction provides extra edge durability for heavy-duty deburring tasks
• Aluminum oxide mineral is compatible with ferrous metals, non-ferrous metals, and aluminum
• Bidirectional operation — runs clockwise and counterclockwise for versatile tool pairing
• Open web structure resists loading and extends abrasive service life
• 800 Series density rated above 700 Series for increased longevity in demanding applications
• 1 inch arbor center hole mounts via unitized wheel mandrel (sold separately)

Compatibility

Designed as an OEM-style replacement or direct-use unitized abrasive wheel for standard angle grinders, bench grinders, and power tools accepting a 6 inch diameter wheel with a 1 inch arbor and a compatible unitized wheel mandrel.

Installation Notes

Installation should be performed by qualified personnel familiar with abrasive wheel safety per ANSI B7.1 guidelines. Ensure all power tools are fully de-energized and unplugged before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use and never exceed the maximum RPM rating of the tool. A unitized wheel mandrel is required for mounting and is sold separately.
