3M 7100145436 Cubitron Ii Hookit 775L Disc 400 Grit 5 Inch

Product Description

The 3M 7100145436 is a Cubitron II Hookit 775L coated abrasive film disc designed for high-speed stock removal on a wide range of substrates. It features 3M Precision Shaped Grain, a ceramic mineral engineered with a triangular geometry that slices through material rather than plowing or gouging like conventional abrasives. At 5 inches in diameter and 400 grit, this disc delivers a fine but fast cut. Rated to cut up to 2x faster and last up to 6x longer than conventional abrasive discs, it is a go-to choice for fabricators, body technicians, and finishing trades requiring consistent, controlled material removal.

This disc is suited for stock removal operations in metal fabrication, automotive bodywork, and general surface preparation. The film backing provides greater tear resistance and edge retention compared to paper-backed alternatives, making it well-suited for contoured surfaces and detail work. The hook-and-loop attachment system allows fast disc swaps on compatible random orbital and disc sanders, reducing downtime during production or service work. It is sold individually and is appropriate for light finishing passes as well as aggressive intermediate stock removal at the 400-grit level.

Installation Notes

Ensure the sander backing pad is clean and free of debris before attaching the disc to maintain full hook-and-loop engagement. Inspect the disc before use and discard if torn, glazed, or loaded. Follow sander manufacturer recommendations for maximum RPM to avoid disc failure. Always use appropriate eye protection and respiratory equipment when grinding or sanding.
