3M 7100044587 Cubitron Ii Hookit Disc 6 Inch 80 Grit

Product Description

The 3M 7100044587 is a coated abrasive hook-and-loop disc engineered for aggressive stock removal on metal, wood, and composite surfaces. Built on the Cubitron II platform, this disc uses 3M Precision Shaped Grain — a triangular ceramic mineral that slices through material rather than plowing or grinding like conventional abrasive grains. The result is a disc rated to cut up to two times faster and last up to four times longer than standard abrasives. At 6 inches in diameter with an 80-grit cut and a maximum operating speed of 12,000 RPM, it is suited for grinding, blending, and heavy material removal in professional fabrication and finishing workflows.

This disc is designed for use on angle grinders and random orbital sanders equipped with hook-and-loop backup pads. The 80-grit designation targets initial stock removal passes on steel, aluminum, stainless, and painted or primed surfaces. Its hook-and-loop attachment system allows fast disc swaps without tools, reducing downtime during high-volume production runs. Licensed fabricators, metal finishers, and sheet metal contractors are the primary users. It is also applicable in automotive body work and general industrial grinding where consistent cut rate and disc longevity matter.

Key Features

• 3M Precision Shaped Ceramic Grain slices material for faster, cleaner cuts versus conventional abrasives
• Cuts up to 2x faster than standard coated abrasive discsService life up to 4x longer than conventional abrasives, reducing disc changeouts
• Hook-and-loop backing enables tool-free disc changes on compatible backup pads
• 6-inch diameter fits standard angle grinder and random orbital sander backup pads
• 80 grit suited for aggressive stock removal and initial surface prep

Compatibility

Designed for use with 6-inch hook-and-loop backup pads on angle grinders and random orbital sanders rated to a minimum of 12,000 RPM. No specific model compatibility data was provided in the product input.

Installation Notes

Always verify that the backup pad and tool are rated for at least the disc maximum speed of 12,000 RPM before mounting. Inspect the disc for tears, damage, or contamination before each use and discard any damaged disc immediately. Ensure the hook-and-loop pad surface is clean and free of debris so the disc seats fully and does not detach during operation. Use appropriate PPE including eye protection, hearing protection, and gloves in accordance with applicable ANSI and OSHA standards for abrasive wheel operations.
