3M 7000047072 Surface Conditioning Fe Disc 7 Inch Coarse

Product Description

The 3M 7000047072 is a 7-inch Surface Conditioning FE Disc designed for edge work, deburring, blending, and coating removal on metal surfaces. Built on a flexible FE substrate, it uses an Aluminum Oxide abrasive that delivers high initial cut rate and maintains extended cut performance throughout the disc's life. The coarse grade makes it well suited for applications requiring aggressive stock removal and high contact pressure. It attaches via a Hook and Loop system for fast disc changes without tools. Licensed tradespeople in metal fabrication, welding shops, and industrial maintenance rely on this disc for consistent results on both flat and contoured workpieces.

This disc is intended for use on ferrous materials where high contact pressure and efficient stock removal are priorities. Typical applications include blending weld seams, removing scale or rust, light deburring of cut edges, and stripping old coatings from steel and iron components. The flexible FE backing allows the disc to conform to contoured surfaces, making it practical for curved or irregular workpiece geometry in both production and field maintenance environments. The 0.87-inch arbor hole fits standard angle grinder and disc sander spindles common in metal fab shops.

Key Features

• Aluminum Oxide abrasive on flexible FE material for high initial and extended cut rate
• Coarse grade suited for aggressive stock removal and deburring
• Hook and Loop attachment system enables fast, tool-free disc changes
• High edge durability supports consistent performance during edge work and contour blending
• Effective on ferrous metals under high contact pressure
• Flexible backing conforms to flat and contoured surfaces

Compatibility

Designed for use with angle grinders and disc sanders equipped with a 7-inch Hook and Loop backing pad and a 0.87-inch arbor, primarily for ferrous metal applications.

Installation Notes

Installation and disc changes should be performed with the grinder unplugged or the power source locked out. Confirm the backing pad diameter and arbor size match before mounting. Operators should wear appropriate PPE including eye protection and gloves when working with abrasive discs. Follow applicable ANSI B7.1 and tool manufacturer guidelines for maximum operating speed and safe disc use.
