3M 7100064272 Cubitron Ii Hookit 775L Film Disc 180 Grit 6 in

Product Description

The 3M 7100064272 is the Cubitron II Hookit 775L coated abrasive film disc, a 6-inch hook-and-loop disc built for aggressive stock removal on metal, composites, and painted surfaces. It uses 3M Precision Shaped Grain technology, a triangular ceramic mineral engineered to continuously fracture and slice through material rather than plowing or smearing like conventional abrasive grains. The 180-grit rating positions this disc for finishing and fine stock removal stages. The polyester film backing resists tearing and holds its edge geometry through extended use, making it a reliable choice for production grinding and surface preparation work performed by metal fabricators, auto body technicians, and industrial finishing crews.

This disc is suited for flat and contoured surface work on steel, aluminum, stainless, fiberglass, and similar substrates. The hook-and-loop attachment system allows fast disc swaps on compatible random orbital and disc sanders without tools, reducing downtime during multi-stage finishing operations. At 180 grit, it fits between coarser material removal passes and final pre-paint or pre-coat surface prep steps. It performs consistently in both hand-held and inline power tool configurations common in fabrication shops, refinishing booths, and maintenance grinding applications.

Key Features

• 3M Precision Shaped Grain ceramic mineral cuts up to 2 times faster than conventional abrasives
• Ceramic grain lasts up to 6 times longer than standard abrasive minerals
• Polyester film backing provides superior tear resistance and maintains edge retention under load
• Hook-and-loop attachment enables tool-free disc changes on compatible sanders
• 180 grit targets fine stock removal and pre-finish surface preparation
• Suitable for a wide range of substrates including steel, aluminum, fiberglass, and composites

Compatibility

Designed for use with hook-and-loop compatible random orbital sanders and disc sanders accepting 6-inch abrasive discs.

Installation Notes

Attach the disc firmly to a clean, dry hook-and-loop backup pad before operation. Inspect the pad face for debris or worn hooks that can cause uneven disc seating or premature release. Always wear appropriate eye protection and respiratory protection when grinding or abrading metal and composite substrates. Disconnect or power down the tool before mounting or removing the disc.
