3M 7000120856 Deburring Disc 8 in Very Coarse Silicon Carbide

Product Description

The 3M 7000120856 is a silicon carbide deburring disc designed to remove burrs, sharp edges, and surface irregularities from metal and other hard materials. The disc measures 8 inches in diameter with a 1/2 inch arbor center hole and is rated to a maximum of 3,000 RPM. The very coarse grade cuts aggressively, making it well suited for heavy deburring and edge-breaking tasks where material removal speed matters. Machinists, fabricators, pipefitters, and industrial maintenance technicians are the typical end users for this type of abrasive tooling.

This deburring disc fits arbor-style right-angle grinders and bench-mounted disc tools commonly found in metal fabrication shops, pipe fitting operations, and mechanical maintenance environments. It is appropriate for use on ferrous and non-ferrous metals where fast, consistent deburring is required after cutting, drilling, or grinding operations. The silicon carbide abrasive material is well suited for harder, more brittle substrates where aggressive material removal is the priority.

Key Features

• 8 inch diameter disc provides a wide working surface for efficient deburring coverage
• Silicon carbide abrasive delivers aggressive cutting action on hard materials
• Very coarse grade for fast material removal and heavy edge-breaking
• 1/2 inch arbor center hole for secure mounting on compatible disc tools
• 3,000 RPM maximum speed rating for use with standard arbor-drive grinders
• Black disc construction consistent with silicon carbide abrasive tooling

Compatibility

Designed for use with arbor-style disc grinders and bench disc tools accepting an 8 inch diameter disc with a 1/2 inch center arbor hole.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive disc tooling. Before mounting, confirm the tool spindle speed does not exceed the 3,000 RPM maximum rating of this disc. Ensure the power tool is fully de-energized and unplugged before changing discs. Inspect the disc for cracks or damage before each use and never operate a damaged abrasive disc.
