3M 7100145449 Abrasive Disc Roll 6 Inch 240 Grit Film

Product Description

The 3M 7100145449 is a coated abrasive disc roll in the Cubitron II 775L series, designed for high-efficiency stock removal on a wide range of substrates. Each disc measures 6 inches in diameter and carries a 240 grit rating. The film backing provides superior tear resistance and edge retention compared to paper-backed alternatives. At the core of the 775L is 3M Precision Shaped Ceramic Grain, a triangular mineral that slices through material rather than gouging, delivering cut rates up to two times faster and service life up to six times longer than conventional abrasive discs. This roll format is suited for shops and field crews running high-volume sanding operations.

The 775L disc roll is built for stock removal applications across metal fabrication, woodworking, composites, and general surface preparation. The Stikita attachment system allows fast disc changes without adhesive mess or downtime, making it practical for production environments where throughput matters. The film backing holds its shape under pressure, maintaining consistent surface contact across curved and flat workpieces alike. This product ships as a roll with a minimum order quantity of 4 units per order.

Key Features

• 3M Precision Shaped Ceramic Grain slices substrate for up to 2x faster cut than conventional abrasives
• Grain geometry extends disc life up to 6x longer than conventional abrasive discs
• Film backing delivers greater tear resistance and edge retention over paper alternatives

Compatibility

Designed for use with 6 inch diameter Stikita-compatible disc sanders and backing pads. Suited for stock removal on metal, wood, composites, and similar substrates.

Installation Notes

Installation is performed by pressing the Stikita-backed disc firmly onto a compatible 6 inch backing pad — no adhesive is required. Power down and disconnect the sander from its power source before changing discs. Inspect the backing pad for wear or contamination before attaching a fresh disc, as a damaged pad will reduce disc contact and cut performance. Dispose of worn discs per facility waste guidelines.
