3M 7000120873 Deburring Wheel Aluminum Oxide Density 6

Product Description

The 3M 7000120873 is a small-diameter unitized deburring wheel designed for precision edge finishing, deburring, and surface blending on metal workpieces. Built with aluminum oxide abrasive at a density grade of 6 (Hard), this wheel delivers consistent cut and finish on ferrous and non-ferrous metals. At 0.5 inches in diameter with a 0.125-inch face width and a 0.125-inch center hole, it fits compact tooling used for tight-area work. The wheel is rated to 40,100 RPM, making it compatible with high-speed rotary tools. Metalworking professionals and fabricators use this wheel where burr removal and light surface conditioning are required in hard-to-reach zones.

This deburring wheel is suited for light industrial and shop metalworking applications involving edge deburring, weld blending, and surface preparation. It is compatible with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. Its compact size makes it well suited for internal bore work, slot deburring, and fine finishing tasks where larger wheels cannot access the work area.

Key Features

• Aluminum oxide abrasive construction for consistent cutting action on metal surfaces
• Density 6 Hard grade for aggressive deburring with controlled material removal
• Rated to 40,100 RPM for use with high-speed die grinders and inline sanders
• Compact 0.5-inch diameter and 0.125-inch face width for tight-access finishing
• 0.125-inch center hole fits standard small-shank rotary tool mandrels
• Unitized wheel construction maintains consistent performance throughout wheel life

Compatibility

Compatible with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. Verify mandrel shank size matches the 0.125-inch center hole before mounting.

Installation Notes

Installation should be performed by a qualified metalworker or tooling technician. Confirm that the tool spindle speed does not exceed the 40,100 RPM maximum rating before mounting the wheel. Power down and de-energize all equipment before changing abrasive wheels. Follow ANSI B7.1 safety standards for the mounting and use of abrasive wheels, and always use appropriate eye and face protection during operation.
