3M 7000045875 Deburring Wheel Aluminum Oxide Density 7

Product Description

The 3M 7000045875 is a unitized deburring wheel designed for edge finishing, light deburring, and surface blending on metal workpieces. Built with aluminum oxide abrasive at a hard density grade 7, it delivers consistent cut and finish in demanding production environments. The wheel measures 3 inches in diameter with a 1/8-inch face width and a 1/4-inch center hole. Rated to 18,100 RPM, it handles high-speed tooling without compromise. Machinists, fabricators, and metalworkers install this wheel when they need repeatable results on tight tolerances or contoured edges.

This deburring wheel is suited for use in light industrial and job shop environments where consistent surface preparation is required. The unitized construction maintains its shape throughout the wheel life, providing uniform contact on inside diameters, edges, and flat surfaces. Compatible tooling includes centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. It is appropriate for ferrous and non-ferrous metal finishing applications requiring a medium cut action with a hard density backing.

Key Features

• Aluminum oxide abrasive for consistent cut on steel, stainless, and non-ferrous metals
• Density 7 hard grade construction resists breakdown under sustained pressure
• Unitized wheel design maintains shape and contact consistency throughout service life
• 18,100 RPM maximum speed rating compatible with high-speed die grinders and inline sanders
• 1/4-inch center hole fits standard mandrel arbors used on common bench and handheld tooling
• Narrow 1/8-inch face width suited for edge work, slots, and tight-radius deburring

Compatibility

Designed for use with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands equipped with a 1/4-inch arbor and capable of operating within the 18,100 RPM maximum speed rating.

Installation Notes

Installation should be performed by qualified personnel familiar with abrasive wheel safety practices. Ensure the spindle speed of the tool does not exceed the 18,100 RPM maximum rating marked on the wheel before mounting. Power down and disconnect the tool completely before mounting or removing the wheel. Inspect the wheel for cracks or damage prior to each use and never force-fit the center hole onto an oversized arbor.
