3M 7100075209 Cubitron Ii 775L 5 Inch 150 Grit Abrasive Disc

Product Description

The 3M 7100075209 is a coated abrasive disc in the Cubitron II 775L series, designed for aggressive stock removal on a range of metal and composite substrates. It uses 3M Precision Shaped Grain technology, a ceramic abrasive mineral formed into a triangular shape that slices through material rather than plowing or gouging the surface. The disc measures 5 inches in diameter and carries a 150 grit rating, making it well suited for finishing passes after heavy grinding. The film backing provides greater tear resistance and edge retention compared to paper-backed alternatives. Maximum operating speed is 12,000 RPM. Licensed trade professionals and fabricators are the primary installers and users.

This disc is suited for stock removal operations on ferrous and non-ferrous metals, painted surfaces, and composites in industrial, manufacturing, and job-site environments. The Hookit attachment system allows for fast disc changes without tools, reducing downtime during high-volume surface prep work. It is appropriate for both bench-mounted and handheld random orbital or disc sanders equipped with a compatible Hookit backup pad. Applications include weld blending, surface conditioning, and material removal prior to finishing.

Key Features

• Precision Shaped Ceramic Grain slices substrate for faster cut and longer disc life compared to conventional abrasives
• Cuts reported up to 2x faster than conventional abrasive discs
• Film backing resists tearing and maintains edge integrity during aggressive use
• Hookit attachment system enables tool-free disc changes
• 5 inch diameter and 150 grit rating suited for stock removal and pre-finishing work
• Rated to 12,000 RPM for use with standard disc sanders

Compatibility

Designed for use with Hookit-compatible backup pads on random orbital and disc sanders that accept 5 inch hook-and-loop abrasive discs rated to 12,000 RPM or higher.

Installation Notes

Installation and use should be performed by qualified personnel familiar with abrasive disc safety standards. Always confirm the tool's rated RPM meets or exceeds the disc maximum of 12,000 RPM before mounting. Inspect the disc for damage before each use and never use a disc that shows tearing, delamination, or compromised backing. Ensure the backup pad is clean and free of debris before attaching the disc to maintain proper adhesion throughout the operation.
