3M 7000120739 Deburring Wheel Aluminum Oxide 3 in

Product Description

The 3M 7000120739 is an aluminum oxide unitized deburring wheel designed for edge finishing, light stock removal, and surface blending on metal workpieces. With a density rating of 8 and a hard density grade, this wheel delivers consistent cutting action and resists loading during use. It runs at a maximum of 18,100 RPM, making it suitable for high-speed rotary tools used in production and maintenance environments. At 3 inches in diameter with a 1/8 inch face width and a 1/4 inch center hole, the compact form factor fits a range of handheld and bench-mounted equipment. Metal fabricators, machinists, and maintenance technicians are the primary users.

This wheel is used for deburring, blending, and light finishing on ferrous and non-ferrous metals in both shop and field settings. Its medium grade and hard density make it appropriate for applications where controlled, repeatable material removal is needed without aggressive cutting. Compatible tooling includes centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. The 1/4 inch arbor hole is a common size across these tool categories.

Compatibility

Compatible with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. The 1/4 inch center hole and 18,100 RPM rating should be verified against tool specifications before use.

Installation Notes

Installation should be performed by a qualified operator following the tool manufacturer's mounting instructions. Always power down and disconnect the tool before mounting or removing the wheel. Confirm that the tool's rated RPM does not exceed the wheel's 18,100 RPM maximum before operation. Inspect the wheel for damage before each use and do not use a wheel that shows cracking, fraying, or deformation.
