3M 7000046885 Surface Conditioning Rc Disc 5 Inch Coarse

Product Description

The 3M 7000046885 is a Surface Conditioning RC Disc designed for deburring, blending, cleaning, and finishing on composites and soft metals. Built on an RC (radial cut) substrate, it combines edge durability with flexibility to deliver consistent cut rate from first use through the life of the disc. The abrasive mineral is aluminum oxide, which provides reliable stock removal under average to moderate pressure without loading quickly. At 5 inches in diameter and rated to 7000 RPM, it is sized for standard angle grinders and disc pad holders used in fabrication, metal finishing, and light prep work.

This disc is suited for general-purpose surface conditioning tasks in fabrication shops, maintenance environments, and light manufacturing. Typical applications include coating removal, surface blending, weld blending, and light deburring on flat surfaces. The RC material construction makes it most efficient on flat or near-flat workpieces. It attaches via a hook and loop system, allowing quick disc changes without tools. Composites and soft metals such as aluminum are the primary target materials, though the coarse grade can handle initial blending passes on a range of softer substrates.

Key Features

• Aluminum oxide mineral on RC substrate delivers good initial and extended cut rate
• High edge durability and flexibility for consistent performance across the disc life
• Coarse grade suited for blending, coating removal, and light deburring
• Hook and loop attachment enables fast disc changes on compatible pad holders
• Most efficient on flat surfaces made of composites or soft metals
• Rated to 7000 RPM for use with standard angle grinders

Compatibility

Designed for use with 5-inch hook and loop disc pad holders on angle grinders and finishing tools rated at or above 7000 RPM. Intended for use on composites and soft metals.

Installation Notes

Inspect the disc and pad holder for damage before mounting. Ensure the grinder is rated at or above the disc RPM rating before powering on. Always wear appropriate eye and face protection, and keep bystanders clear of the work area when grinding. Do not exceed the rated 7000 RPM.
