3M 7000045845 Deburring Wheel 3in Aluminum Oxide Unitized

Product Description

The 3M 7000045845 is a unitized deburring wheel designed for edge blending, light deburring, and surface finishing on metal workpieces. Built with aluminum oxide abrasive at a coarse grade and density 7 hardness, this wheel delivers consistent cut and durability across repeated passes. The 3-inch diameter and 1/4-inch face width make it well suited for targeted deburring work in tight profiles. It is rated to 18,100 RPM and mounts via a 1/4-inch center hole, fitting a range of standard rotary tooling. Metalworking professionals, fabricators, and machine shop technicians are the primary installers and users of this wheel.

This deburring wheel is appropriate for both light production runs and maintenance deburring tasks on steel, aluminum, and similar metals. Its unitized construction keeps the wheel diameter and surface condition relatively consistent throughout the life of the wheel, reducing the need for frequent dressing. Compatible tooling includes centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands, making it a versatile choice across common metalworking setups found in fabrication shops and industrial maintenance environments.

Installation Notes

This wheel should be installed and operated by trained metalworking technicians familiar with abrasive wheel safety. Always confirm that the spindle speed of the tool does not exceed the 18,100 RPM maximum rating of the wheel before mounting. Inspect the wheel for damage before each use and ensure the arbor nut is properly secured before starting the tool. Follow ANSI B7.1 safety guidelines for the use, care, and protection of abrasive wheels.
