3M 7000046013 Deburring Disc 5 in Very Coarse Silicon Carbide

Product Description

The 3M 7000046013 is a silicon carbide deburring disc designed for aggressive material removal on metal, plastic, and composite surfaces. At 5 inches in diameter with a 1/2-inch arbor hole, it mounts securely to standard angle grinders and disc sanders. The very coarse grade makes it well-suited for removing sharp burrs, flash, and rough edges left after cutting, drilling, or stamping operations. It is rated to a maximum of 5,000 RPM, keeping it compatible with a wide range of variable-speed and fixed-speed power tools used in fabrication and maintenance environments. Machinists, pipe fitters, and general maintenance technicians are the primary installers.

This disc is used in light industrial and trade applications where quick deburring and surface cleanup are required. Typical scenarios include post-cut pipe prep, weld seam cleanup, and removing casting flash on metal components. The silicon carbide abrasive cuts fast on non-ferrous metals, cast iron, and hard plastics, making it a practical choice for shops that work across multiple material types. The arbor mount allows for fast disc changes on compatible backing pads.

Compatibility

Designed for use with arbor-style backing pads on angle grinders and disc sanders that accept 5-inch abrasive discs with a 1/2-inch center hole and operate at or below 5,000 RPM.

Installation Notes

Installation should be performed by a qualified technician familiar with angle grinder and abrasive disc safety. Always power down and unplug the tool before mounting or removing the disc. Confirm the tool's rated speed does not exceed the disc's 5,000 RPM maximum before use. Inspect the disc for cracks or damage prior to each use and replace immediately if any defects are found.
