3M 7000046887 Surface Conditioning Rc Disc 5 Inch

Product Description

The 3M 7000046887 is a Surface Conditioning RC Disc designed for deburring, blending, cleaning, and finishing work on composites and soft metals. Built on a reinforced combination (RC) substrate, it carries an aluminum oxide abrasive that delivers reliable cut rate at startup and maintains that performance over the life of the disc. The disc measures 5 inches in diameter and is rated for use up to 7000 RPM. A hook-and-loop attachment system makes disc changes fast without tools. It is used in metalworking and fabrication environments where consistent surface finish and edge control matter.

This disc is suited for flat-surface applications on composites and soft metals in both light production and maintenance settings. Its RC material backing provides edge flexibility, which helps reduce gouging during blending and finishing passes. The aluminum oxide abrasive grade is appropriate for general use under average applied pressure. Typical users include metal fabricators, maintenance technicians, and finishing specialists working on panels, frames, and structural components where coating removal, light deburring, and surface prep are routine tasks.

Key Features

• Aluminum oxide abrasive on RC substrate for good initial and sustained cut rate
• 5 inch diameter rated to 7000 RPM
• Hook-and-loop attachment for tool-free disc changes
• High edge durability and flexibility reduce gouging on flat surfaces
• Suitable for deburring, blending, coating removal, cleaning, and finishing
• Very fine grit grade for light material removal and surface refinement

Compatibility

Designed for use with 5 inch hook-and-loop backup pads on angle grinders and random orbital sanders used in surface conditioning applications on composites and soft metals.

Installation Notes

This disc is installed by a metalworker or finishing technician onto a compatible 5 inch hook-and-loop backup pad. Confirm the tool spindle speed does not exceed the 7000 RPM disc rating before operation. Inspect the disc and backup pad for wear or damage before each use, and discard any disc that shows fraying, tears, or delamination. Follow applicable shop safety standards including proper PPE for abrasive grinding operations.
