3M 7000046101 Deburring Disc 8 in Very Fine Aluminum Oxide

Product Description

The 3M 7000046101 is an 8-inch aluminum oxide deburring disc designed for surface conditioning and edge deburring on metal workpieces. Built with a very fine grade abrasive, it removes light burrs, smooths weld seams, and blends surface imperfections without aggressive stock removal. The arbor-style center hole measures 3/4 inches and mounts directly to compatible disc pads or backup holders. Rated to 3000 RPM, this disc suits bench-mounted or handheld angle grinder setups where controlled, fine finishing work is required. Maintenance technicians and fabricators use it on ferrous and non-ferrous metals in light industrial and trade shop environments.

This deburring disc is suited for deburring pipe ends, smoothing drilled holes, and finishing cut edges on sheet metal or structural components. It is a practical choice for HVAC fabricators, plumbers, and pipefitters who need a reliable finishing abrasive after cutting or grinding operations. The very fine grade makes it appropriate for final-pass work where surface finish matters, such as preparing pipe ends before fitting connections or cleaning up rough edges on duct components.

Key Features

• 8-inch diameter provides broad contact area for efficient surface conditioning
• Very fine grade aluminum oxide abrasive for light deburring and surface blending
• 3/4-inch arbor center hole for secure mounting on standard disc pads
• 3000 RPM maximum speed rating for controlled grinder operation
• Maroon color coding for quick grade identification on the job

Compatibility

Designed for use with standard arbor-style disc backup pads and angle grinders that accept 8-inch surface conditioning discs with a 3/4-inch center hole.

Installation Notes

Installation and use should be performed by qualified personnel familiar with abrasive disc safety practices. Always confirm the tool's rated RPM meets or does not exceed the disc's 3000 RPM maximum before mounting. Inspect the disc for damage before each use and ensure the backup pad is properly secured. Follow applicable ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
