3M 7000047076 Surface Conditioning Rc Disc 7 Inch Coarse

Product Description

The 3M 7000047076 is a Surface Conditioning RC Disc engineered for deburring, blending, cleaning, and finishing operations on composites and soft metals. Built on a reinforced composite (RC) backing, the disc combines edge durability with flexibility, delivering strong initial cut rate and sustained stock removal over extended use. The aluminum oxide abrasive layer supports consistent performance at speeds up to 6000 RPM on a 7-inch diameter disc. This product is sold individually and is sized for use with standard angle grinders and disc pad holders common to metal fabrication and surface prep work.

This disc is suited for both shop and field surface conditioning tasks where a general-purpose abrasive is required. It performs best on flat surfaces made of composites or soft metals, handling coating removal, light deburring, surface blending, and finish prep in a single tool setup. Its coarse grade makes it appropriate for more aggressive material removal passes before transitioning to finer finishing steps. Fabricators, metalworkers, and maintenance technicians working on sheet metal, composite panels, and similar substrates will find this disc a practical choice for everyday surface work.

Key Features

• Aluminum oxide abrasive on RC backing for good initial and sustained cut rate
• High edge durability and flexibility for consistent performance across the disc face
• Rated to 6000 RPM for compatibility with standard angle grinders
• Coarse grade suitable for coating removal, blending, and light deburring
• Most efficient on flat surfaces of composites or soft metals
• Hook and loop attachment style for tool-free disc changes

Compatibility

Designed for use with 7-inch disc pad holders and angle grinders that accept hook and loop attachments rated to 6000 RPM or higher.

Installation Notes

Installation and disc changes should be performed with the grinder fully powered off and unplugged. Confirm the grinder's maximum rated speed meets or exceeds the disc's 6000 RPM rating before mounting. Inspect the disc for tears or damage before each use and do not use a damaged disc. Follow applicable ANSI B7 and OSHA grinding safety standards when operating powered abrasive tools.
