3M 7100383698 Abrasive Disc 6 in Ceramic 1000 Grit 775L 50 Pack

Product Description

The 3M 7100383698 is a Cubitron II finishing disc designed for cool-cutting surface preparation across a wide range of materials. Measuring 6 inches in diameter with a multi-hole pattern for dust extraction, this disc uses an open-coat ceramic abrasive bonded to a C-weight film backing. At 1000 grit, it is engineered for fine finishing work where surface smoothness and minimal heat buildup are critical. The open-coat construction resists loading, extending disc life on soft or resinous materials. This product is sold in a 50-pack, making it well suited for production environments and high-volume refinishing operations.

These discs are used in automotive refinishing, marine composite work, and industrial surface finishing applications. The 775L designation indicates the film-backed series within the Cubitron II line, optimized for random orbital sanders and other multi-hole disc tools. Compatible surfaces and substrates include paint, plastic, composites, gelcoat, fiberglass, and carbon steel. Both professional body technicians and fabricators working with composite panels will find this grit and backing combination appropriate for final preparation before coating or topcoat application.

Key Features

• 6-inch diameter with multi-hole pattern for active dust extraction during use
• Open-coat ceramic abrasive resists loading on paint, plastic, and resinous substrates
• C-weight film backing provides flexibility and conformability on curved surfaces
• 1000 grit for fine finishing and pre-coat surface preparation
• 50-pack quantity reduces changeover frequency in production settings
• Cool-cutting formulation minimizes heat transfer to temperature-sensitive substrates

Compatibility

Compatible surfaces and substrates include paint, plastic, composites, gelcoat, fiberglass, and carbon steel. Designed for use with random orbital sanders accepting 6-inch multi-hole hook-and-loop disc pads.

Installation Notes

These discs are installed and replaced by automotive technicians, marine fabricators, and industrial finishing professionals. Ensure the backing pad is clean and free of debris before attaching the disc to maintain full hook-and-loop contact. Inspect each disc before use and discard any disc showing tears, loading, or delamination. Follow the tool manufacturer's RPM rating and do not exceed the maximum speed rating of the sander being used.
