3M 7000120548 Deburring Wheel 6 in Aluminum Oxide Density 7

Product Description

The 3M 7000120548 is an aluminum oxide unitized deburring wheel designed for aggressive material removal and surface conditioning on metal workpieces. Built to a density rating of 7 with a hard grade designation, this wheel delivers consistent cut and finish performance across a range of metals. It measures 6 inches in diameter with a 1/4-inch face width and a 1/2-inch center hole, fitting standard arbors used across common bench and inline grinding equipment. Rated to 7,500 RPM, it is suited for moderate- to high-speed finishing applications where burr removal, edge blending, and light surface conditioning are required. Machinists, fabricators, and metalworking technicians are the primary installers and operators of this wheel.

This deburring wheel is used in industrial metalworking environments where consistent edge deburring and surface finishing are required. The unitized construction maintains its shape and cutting action throughout the wheel life, reducing the need for frequent dressing. It is compatible with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands, making it a versatile fit for shop floor and production line use. Residential and light commercial metalworking shops use this type of wheel for both batch and one-off finishing work.

Key Features

• Aluminum oxide abrasive material for effective cutting on ferrous and non-ferrous metals
• Density 7 hard grade construction for aggressive deburring and edge conditioning
• Unitized wheel design maintains consistent shape and cut throughout wheel life
• 7,500 RPM maximum speed rating for use with standard die grinders and inline sanders
• 6-inch diameter with 1/4-inch face width and 1/2-inch center hole for broad arbor compatibility
• Compatible with multiple machine types including centerless grinders and pressure assist backstands

Compatibility

Designed for use with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. Verify that the host machine arbor accepts a 1/2-inch center hole and operates within the 7,500 RPM maximum speed rating before mounting.

Installation Notes

Always power down and de-energize the host machine before mounting or removing the wheel. Confirm the spindle speed does not exceed the 7,500 RPM maximum rating marked on this wheel — operating above rated speed is a recognized safety hazard. Use the correct arbor and flanges for a 1/2-inch center hole mounting; do not force-fit or modify the bore. Wear appropriate eye protection and follow ANSI B7.1 safety guidelines when operating grinding and finishing wheels.
