3M 7000045947 Deburring Wheel 2 in Aluminum Oxide Coarse

Product Description

The 3M 7000045947 is an aluminum oxide unitized deburring wheel designed for aggressive material removal on metal workpieces. Built to a Density 8 Hard Grade construction, this wheel delivers consistent cutting action across the full face width during deburring, blending, and light grinding operations. It runs at a maximum rated speed of 22,100 RPM, making it compatible with high-speed rotary tools common in fabrication and finishing environments. Licensed HVAC technicians, machinists, and metal fabricators rely on this type of wheel for edge prep and surface conditioning work where controlled abrasion is needed.

This deburring wheel is suited for use with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. Its 2-inch diameter and 1/8-inch face width make it well-matched for detail deburring on tight geometries and small-diameter workpieces. The unitized wheel construction holds abrasive grains in a three-dimensional matrix, allowing the wheel to wear evenly and continuously expose fresh cutting material throughout its service life. It is applicable in light industrial, job shop, and field repair settings.

Installation Notes

Mounting and operation of deburring wheels should be performed by qualified personnel familiar with abrasive wheel safety standards. Always confirm the tool spindle speed does not exceed the 22,100 RPM maximum rating marked on the wheel before mounting. Power down and lock out the tool before installing or removing the wheel. Inspect the wheel for cracks or damage prior to each use and never operate a damaged wheel.
