3M 7100145477 Cubitron Ii 775L Film Disc 400 Grit 3 Inch

Product Description

The 3M 7100145477 is a Cubitron II 775L Hook and Loop Film Disc engineered for aggressive stock removal on a wide range of substrates. At the core of this disc is 3M Precision Shaped Grain, a triangular ceramic mineral that slices through material rather than plowing or gouging the way conventional abrasives do. The result is a disc rated to cut up to two times faster and last up to six times longer than standard abrasive discs. Measuring 3 inches in diameter with a 400 grit rating, it is suited to fine-to-medium stock removal tasks where surface quality and cut rate both matter. The film backing resists tearing and holds its edge through extended use.

This disc is designed for use in metal fabrication, automotive bodywork, and general industrial finishing where fast material removal at a controlled finish level is required. The hook and loop attachment system allows rapid disc changes without tools, making it a practical choice for technicians cycling through multiple grits or working in time-sensitive environments. The 15000 RPM maximum speed rating supports use with standard air-powered and electric random orbital and right-angle disc sanders.

Key Features

• 3M Precision Shaped Ceramic Grain cuts up to 2x faster than conventional abrasives
• Ceramic mineral geometry slices rather than gouges, extending disc life up to 6x
• Film backing provides superior tear resistance and edge retention compared to paper backing
• Hook and loop attachment enables fast, tool-free disc changes
• 400 grit rating suited for controlled stock removal and light surface finishing
• Rated to 15000 RPM for compatibility with common pneumatic and electric sanders

Compatibility

Designed for use with hook and loop backing pads on random orbital and disc sanders accepting 3-inch diameter abrasive discs rated to 15000 RPM or higher.

Installation Notes

Confirm the backing pad is clean, dry, and free of debris before attaching the disc to ensure secure hook and loop engagement. Do not exceed the 15000 RPM maximum speed rating of the disc. Inspect the disc before each use and discard if torn, delaminated, or showing uneven wear. Follow applicable shop safety practices including eye protection and dust collection when grinding or finishing metal or composite substrates.
