3M 7000028479 Deburring Wheel 6 Inch Silicon Carbide

Product Description

The 3M 7000028479 is a unitized deburring wheel designed for surface finishing, edge blending, and light deburring on metal workpieces. Built around a silicon carbide abrasive in a soft, fine-grade density 2 construction, it delivers consistent cut and finish without loading or gouging softer metals. The wheel measures 6 inches in diameter with a 1-inch face width and a 1-inch center hole, and it is rated to a maximum of 5,000 RPM. It is installed by machinists and metalworking professionals on stationary or portable finishing equipment where repeatable surface quality is required.

This deburring wheel is suited for use in shop environments running centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. Typical applications include deburring drilled or machined edges, blending weld seams, and conditioning metal surfaces prior to coating or inspection. The unitized wheel construction maintains a consistent finish throughout the life of the wheel as the abrasive is distributed evenly through the wheel body rather than coated on a surface layer.

Key Features

• Silicon carbide abrasive provides sharp, consistent cut on ferrous and non-ferrous metals
• Density 2 soft grade unitized construction resists loading and maintains open structure during use
• Fine grade abrasive suitable for edge blending, light deburring, and surface conditioning
• 5,000 RPM maximum speed rating compatible with standard die grinder and backstand operating speeds
• 1-inch center hole fits standard arbors used on centerless grinders and inline sanders
• Unitized body wears evenly, delivering uniform finish from first use to last

Compatibility

Compatible with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands equipped with a 1-inch arbor and capable of operating at or below 5,000 RPM.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B7.1 guidelines. Always confirm the machine spindle speed does not exceed the 5,000 RPM maximum rating marked on the wheel before mounting. Inspect the wheel for cracks or damage before each use and never operate a damaged wheel. Ensure the arbor and flanges are clean and properly sized for the 1-inch center hole before securing the wheel.
