3M 7000120870 Deburring Wheel 6 in Aluminum Oxide Density 7

Product Description

The 3M 7000120870 is a unitized deburring wheel designed for surface finishing, edge deburring, and light material removal on metal workpieces. Built with aluminum oxide abrasive at a density grade of 7 (hard), it delivers consistent cut rate and finish across repeated passes. At 6 inches in diameter with a 1-inch face width and a 1-inch center hole, this wheel mounts directly to a range of powered grinding and sanding equipment. Rated for a maximum of 7,500 RPM, it suits both bench-mounted and inline tool configurations. Fabricators, tool and die shops, and metalworking professionals install this wheel for production deburring and blending applications.

This deburring wheel fits centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. The unitized construction keeps the abrasive grain uniformly distributed throughout the wheel body, so performance remains consistent as the wheel wears down. It is suited for medium-volume metalworking environments where repeatable edge finishing and surface conditioning are required on ferrous and non-ferrous parts. The hard density grade makes it appropriate for moderate-to-aggressive deburring passes rather than fine polishing.

Key Features

• Aluminum oxide abrasive with hard density grade 7 for aggressive deburring performance
• Unitized wheel construction maintains consistent finish as the wheel wears
• 6-inch diameter and 1-inch face width suit a wide range of production setups
• 1-inch center hole for direct mounting on standard arbors
• Maximum 7,500 RPM rating compatible with die grinders, inline sanders, centerless grinders, and backstands
• Medium grade finish appropriate for edge breaking and surface blending on metal parts

Compatibility

Compatible with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands that accept a 6-inch diameter wheel with a 1-inch center hole arbor.

Installation Notes

Installation should be performed by a qualified metalworking professional or abrasives technician. Power down and lock out the tool before mounting or removing the wheel. Verify that the tool spindle speed does not exceed the 7,500 RPM maximum rating of this wheel before operation. Inspect the wheel for cracks or damage before each use and never operate a damaged abrasive wheel.
