3M 7000046882 Surface Conditioning Fe Disc 4.5 Inch Medium

Product Description

The 3M 7000046882 is a Surface Conditioning FE Disc engineered for edge work, deburring, blending, and coating removal across all metal types. Built on a flexible non-woven FE substrate with Aluminum Oxide abrasive, the disc delivers high initial cut and sustained material removal through extended use. At 4.5 inches in diameter with a Medium grit grade and a rated speed of 8000 rpm, it handles both flat and contoured surfaces without losing edge integrity. Attachment is via Hook and Loop, allowing fast disc changes at the grinder. Fabricators, welders, and metal finishing technicians are the primary users of this product.

This disc is suited for ferrous and non-ferrous metal preparation tasks in fabrication shops, manufacturing facilities, and field metalwork. Typical applications include weld blending, mill scale removal, light deburring, and surface conditioning prior to coating or inspection. The flexible FE backing allows the disc to conform to contoured surfaces and irregular profiles, maintaining consistent abrasive contact without gouging the workpiece. It performs most efficiently on ferrous materials where higher contact pressure and stock removal rates are required.

Key Features

• Aluminum Oxide abrasive on flexible FE substrate for high initial and extended cut rate
• Medium grit grade suited for blending, coating removal, finishing, and light deburring
• Flexible backing conforms to flat and contoured surface profiles
• High edge durability maintains cutting performance through demanding edge work
• Hook and Loop attachment for fast, tool-free disc changes
• Rated to 8000 rpm for use with standard angle grinders

Compatibility

Designed for use with Hook and Loop-compatible angle grinders and surface conditioning tools accepting 4.5-inch discs. Most efficient on ferrous materials where high contact pressure and stock removal are required.

Installation Notes

Installation and disc changes should be performed by qualified personnel with the grinder disconnected from power. Verify the tool spindle speed rating meets or exceeds the 8000 rpm disc rating before mounting. Inspect the disc for damage before each use and do not use damaged or delaminated discs. Always use appropriate eye and face protection per ANSI Z87.1 and follow applicable workplace safety standards when operating abrasive tools.
