PRODUCT FAQ
-
What materials can I use the 3M™ Cubitron™ II Hookit™ Film Disc 775L on?
You can use the 3M™ Cubitron™ II Hookit™ Film Disc 775L on a variety of materials, including metals, composites, gelcoat, paint, fiberglass, and plastics. It's really versatile for different applications!
-
What makes this disc different from other sanding discs?
The big advantage is its precision-shaped ceramic grain—which cuts faster and lasts longer than conventional abrasive grains. Plus, it helps reduce heat buildup so your surfaces are protected!
-
Is this disc reusable or single-use?
Great question! While each individual disc is designed to be used until it's worn out (so not strictly “reusable”), you can attach and reattach them easily because of the convenient Hookit™ system.
-
What size projects is this pack good for?
With 250 discs per case (50 discs per carton), you'll have plenty for medium to large projects—perfect for workshops that need consistent performance over multiple jobs!
Now featuring an expanded grade range up to 1000+, these discs are engineered to accommodate a wide array of sanding and finishing tasks. Whether you require aggressive stock removal or precise fine finishing, these discs deliver reliable performance across a broad spectrum of applications.
Effective on Multiple SubstratesDesigned for versatility, these discs perform exceptionally well on a variety of materials, including metals, composites, all types of wood, as well as painted surfaces, primers, and other coatings. This makes them an excellent choice for professionals seeking a single solution for diverse surface preparation and finishing needs.
Durable Film Backing for Enhanced PerformanceThe robust film backing provides superior tear resistance compared to traditional paper discs. This added durability ensures the discs maintain their integrity and edge retention, even during demanding wet or dry sanding operations. As a result, users benefit from longer-lasting abrasives and consistent results.
Optimized for 3M Xtract Random Orbital SandersFor optimal performance and efficiency, these discs are best paired with 3M Xtract Random Orbital Sanders. This combination maximizes dust extraction, enhances productivity, and helps achieve a cleaner work environment, all while delivering a high-quality finish.
3M Hookit System for Clean, Reusable AttachmentThe comprehensive line of 3M Hookit discs is specifically designed for environments where adhesive-backed discs may be compromised by dust or debris. The Hookit system utilizes a convenient hook-and-loop attachment method, allowing discs to be easily attached, removed, and reused throughout their lifespan. This not only improves cost-effectiveness but also reduces waste and downtime.
Achieve Finer Finishes with Less AggressionCompared to 3M Stikit discs, Hookit discs are less aggressive, making them ideal for applications where a finer finish is desired. Their reusable nature and clean removal further enhance their value, making them a preferred choice for professionals focused on both quality and efficiency.
