3M 7010330803 Surface Conditioning Rc Disc 7 Inch Medium

Product Description

The 3M 7010330803 is a 7-inch Surface Conditioning RC Disc built for deburring, blending, cleaning, and finishing on composites and soft metals. The disc uses an Aluminum Oxide abrasive on a reinforced composite (RC) backing, which combines edge durability with flexibility for consistent cut rate from first use through the life of the disc. Hook and Loop attachment makes disc changes fast without tools. This disc is sized for angle grinders and right-angle disc tools rated to 6000 RPM and is typically installed by metalworkers, fabricators, HVAC sheet metal technicians, and maintenance trades.

This disc suits general-purpose surface conditioning at medium grit across flat and near-flat workpiece geometry. It performs best on composites, aluminum, copper, and other soft or non-ferrous metals where controlled material removal without aggressive loading is required. Medium grit makes it a practical choice for blending welds, removing coatings, light deburring, and prep before finishing. It is not optimized for high-pressure or aggressive stock removal on ferrous steel.

Key Features

• Aluminum Oxide abrasive on RC backing delivers good initial and sustained cut rate
• High edge durability and disc flexibility for controlled surface contact
• Medium grit suited for blending, coating removal, light deburring, and finishing
• Hook and Loop attachment system allows fast, tool-free disc changes
• Rated to 6000 RPM for compatibility with standard angle grinder tooling
• Most efficient on flat surfaces of composites or soft non-ferrous metals

Compatibility

Designed for use with Hook and Loop 7-inch disc backing pads on angle grinders and right-angle surface conditioning tools rated at or below 6000 RPM. Optimized for composites and soft metals including aluminum and copper alloys.

Installation Notes

Mounting and removal of Hook and Loop abrasive discs should be performed with the tool unplugged or the power source isolated. Confirm the tool's rated RPM meets or exceeds the disc's 6000 RPM maximum before use. Inspect the backing pad for wear or debris before attaching the disc to ensure secure seating. Eye protection and appropriate respiratory PPE are required when grinding or surface conditioning operations generate dust or sparks.
