3M 7000000774 Metal Finishing Wheel 12x24x5 in 6A Med

Product Description

The 3M 7000000774 is a convolutely wound metal finishing wheel designed to produce uniform satin finishes on metal surfaces. Built with a medium-grade aluminum oxide abrasive mineral, this wheel delivers consistent, controlled cut and finish action across the workpiece. The 6A density rating indicates a hard, long-lasting construction that resists wear under sustained use. At 12 inches in diameter, 24 inches in face width, and 5 inches in bore size, it is sized for industrial-scale finishing operations. Metalworking shops, fabricators, and maintenance machinists rely on this wheel for deburring, blending, and surface conditioning tasks where a repeatable satin finish is required.

This finishing wheel is suited for industrial and manufacturing environments where consistent surface finish quality is critical. It is appropriate for use on ferrous and non-ferrous metals in applications such as weld blending, scale removal, and pre-polish conditioning. The convolutely wound construction allows the abrasive to conform slightly to the workpiece surface, making it effective on flat stock, tubing, and structural shapes. It installs on stationary finishing machines, lathes, or custom mandrel setups equipped to accept a 5-inch bore arbor.

Key Features

• Convolutely wound construction for consistent abrasive delivery throughout wheel life
• Medium-grade aluminum oxide abrasive mineral for controlled cut and uniform satin finish
• 6A density rating provides hard, long-lasting performance under sustained load
• 12 inches x 24 inches x 5 inches dimensions suit industrial-scale finishing equipment
• Designed for deburring, blending, scale removal, and surface conditioning on metal

Compatibility

Designed as an OEM-style replacement or direct-use finishing wheel for industrial stationary finishing machines and lathes equipped with a 5-inch bore arbor and sufficient face-width capacity to accept a 24-inch wide wheel.

Installation Notes

Installation should be performed by qualified machinists or maintenance personnel familiar with abrasive wheel mounting procedures. Before mounting, confirm that the machine spindle speed rating does not exceed the maximum operating speed marked on the wheel. Power down and lockout the machine per OSHA lockout/tagout procedures before mounting or removing the wheel. Inspect the wheel for visible damage before each use and ensure all flanges, blotters, and arbor hardware are correctly seated before operating.
