3M 7100015817 Surface Conditioning Rc Disc 4 Inch Medium

Product Description

The 3M 7100015817 is a Surface Conditioning RC Disc engineered for deburring, blending, cleaning, and finishing on composites and soft metals. Built on a reinforced composite (RC) substrate, it combines edge durability with flexibility to maintain consistent cut rate from the first pass through extended use. The aluminum oxide abrasive mineral delivers a reliable, moderate cut suited to medium-pressure applications. At 4 inches in diameter and rated to 8,000 rpm, this disc fits standard right-angle grinders and die grinders commonly used in fabrication and maintenance environments. Installation is straightforward using the hook-and-loop attachment system.

This disc is well suited to flat surface work on composites, aluminum, and other soft metals in both shop and field settings. Typical applications include weld blending, light coating removal, surface preparation before bonding or painting, and general finishing work. The medium grit rating makes it effective for material removal without aggressive stock loss, which is useful when working on thin-gauge materials or surfaces requiring a controlled finish. Fabricators, maintenance technicians, and metalworkers handling general-purpose surface conditioning tasks will find this disc a practical fit for everyday use.

Key Features

• Aluminum oxide abrasive on RC substrate provides consistent initial and extended cut rate
• Edge durability and flexibility support use on contoured and flat surfaces
• Hook and loop attachment system for quick disc changes
• Medium grit rating suited to blending, light deburring, and finishing
• Rated to 8,000 rpm for use with standard right-angle and die grinders
• Effective on composites, aluminum, and other soft metals

Compatibility

Designed for use with right-angle grinders and die grinders that accept 4-inch hook-and-loop disc backups and operate within an 8,000 rpm maximum speed rating.

Installation Notes

Installation is performed by fabricators or maintenance technicians familiar with angle grinder operation. Always confirm the grinder speed rating does not exceed the disc maximum of 8,000 rpm before mounting. Inspect the hook-and-loop backup pad for wear before attaching the disc, and ensure the disc seats fully and evenly. Wear appropriate PPE including eye protection and gloves during operation.
