3M 7000028450 Deburring Wheel Aluminum Oxide Density 8

Product Description

The 3M 7000028450 is an aluminum oxide unitized deburring wheel engineered for aggressive material removal on metal workpieces. With a density rating of 8 and a hard grade designation, this wheel delivers consistent cutting action across its full face width of 0.25 inches. The 3-inch diameter and 0.25-inch center hole size make it compatible with a range of rotary tooling. Rated to 18,100 RPM, it handles high-speed applications without sacrificing control. Machinists, fabricators, and metal finishing technicians use this wheel where a coarse cut is required to remove burrs, flash, or light surface defects efficiently.

This deburring wheel is suited for use in metalworking and fabrication environments, including both production shops and maintenance settings. Its unitized construction keeps the abrasive uniformly distributed throughout the wheel body, so cutting performance stays consistent as the wheel wears. Typical applications include edge deburring on machined parts, weld cleanup, and surface blending on ferrous and non-ferrous metals. The coarse grade makes it most effective where rapid material removal is the priority rather than fine finishing.

Key Features

• Aluminum oxide abrasive material rated for coarse-grade cutting action
• Density 8 hard grade unitized construction for consistent, even wear across the wheel body
• Maximum operating speed of 18,100 RPM for compatibility with high-speed rotary tools
• 3-inch wheel diameter with 0.25-inch face width and 0.25-inch center hole
• Compatible with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands
• Specification designation 8ACRS

Compatibility

Designed for use with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands accepting a 0.25-inch arbor hole and a 3-inch diameter wheel.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with abrasive wheel safety. Before mounting, confirm that the tool spindle speed does not exceed the 18,100 RPM maximum rating marked on the wheel. Power down and lock out the tool before mounting or removing the wheel. Always inspect the wheel for cracks or damage before each use and follow ANSI B7.1 safe mounting and guarding practices for abrasive wheels.
