3M 7010310104 Surface Conditioning Disc 5 Inch Coarse Ao

Product Description

The 3M 7010310104 is a 5-inch Surface Conditioning RC Disc designed for deburring, blending, cleaning, and finishing on composites and soft metals. Built on a reinforced RC backing material, this disc combines high edge durability with flexibility, allowing it to conform to workpiece geometry without breaking down prematurely. The aluminum oxide abrasive grain delivers a reliable initial cut rate and maintains consistent stock removal through the life of the disc. Attachment is handled by a Hook and Loop system, making disc changes fast without additional hardware. This disc is suited for flat-surface work at average to moderate pressure levels.

This disc is intended for fabrication, metalworking, and finishing applications in light industrial and shop environments. It performs best on flat surfaces made of composites, aluminum, and other soft metals where a consistent surface profile is required. Typical applications include coating removal, surface blending prior to paint or inspection, and light deburring of edges and welds. The coarse grade makes it appropriate for material removal and preparation stages rather than final finishing passes.

Key Features

• Aluminum oxide abrasive grain for reliable initial and extended cut rate
• RC backing material provides high edge durability and disc flexibility
• Coarse grade suited for deburring, blending, and coating removal
• Hook and Loop attachment for fast, tool-free disc changes
• Optimized for flat surfaces on composites and soft metals
• 5-inch diameter with 0.87-inch arbor for standard disc pad compatibility

Compatibility

Designed for use with 5-inch Hook and Loop disc pads with a 0.87-inch arbor, compatible with standard right-angle grinders and disc sanders configured for surface conditioning applications on composites and soft metals.

Installation Notes

Installation is performed by pressing the disc firmly onto a compatible Hook and Loop backup pad mounted to an angle grinder or disc sander. Ensure the tool is powered off and unplugged before attaching or removing the disc. Inspect the backup pad for wear or damage before each disc change, as a degraded pad reduces holding force and disc stability. Always use appropriate PPE including eye protection and gloves when operating abrasive grinding equipment.
