Built for Longer Disc Life
So much technology in one abrasive disc: our 3M™ Hookit™ Purple Clean Sanding Abrasive Disc 334U cuts fast, lasts long, resists loading and leaves a consistent finish across a wide range of applications. It features durable, fast-cutting aluminum oxide abrasive built on C-weight paper backing. A spiral pattern, made up of many tiny holes, keeps particulates away from the surface to reduce loading. When used with dust extraction systems dust will be captured rather than staying on the sanding surface or floating in the air. This pattern also eliminates the need for hole alignment, making it faster and easier to change the discs and extending the abrasive’s useful life. Discs are available in grades P240 – P800, ideal for featheredging, fine featheredging or as a last step before priming. They are also great for prepping before blending. Our Hookit™ attachment system makes for fast and efficient disc change-outs without tools.
Hard, Tough and Sharp
3M’s fast cutting, long lasting abrasive saves labor costs and improves quality. Aluminum oxide is popular among collision repair professionals because of its fast cut-rate and long life. A natural mineral, it makes a tough, durable abrasive that stays sharp longer. Aluminum oxide is suitable for a wide variety of metalworking materials including ferrous alloys. These discs sand fast to improve technician productivity and reduce labor costs, and the consistent finish reduces rework further improving repair efficiency.
Spiral Hole Pattern Helps You Get More from Each Disc
To achieve maximum performance, the discs are designed with small spiral-patterned holes to give dust a better escape route, moving more dust away from your finishing surface without loading the disc.
The spiral hole configuration allows for optimal particulate removal improving performance when used with or without a dust extraction system. When using dust extraction, hole alignment is not necessary to achieve direct air flow from the workpiece through the abrasive disc. Technicians can change these discs more quickly, saving time and promoting re-use, helping preserve abrasive life. In fact, 3M™ Hookit™ Purple Clean Sanding Abrasive Disc 334U can last 2 – 3 times longer than other discs – delivering professional results while improving the bottom line in collision repair.
Our Hookit™ Attachment System
3M offers a complete line of hook-and-loop style Hookit™ discs for work spaces where adhesive backing may become contaminated by dust, dirt, or flying debris. Hookit™ discs conveniently and firmly attach to a hook-and-loop backup disc pad (sold separately). It’s simple: just attach the disc to the backup pad and start sanding. It removes just as easily and cleanly, and can be re-used again and again for the extent of the abrasive life. To ensure easy, fast attachment, the precise spiral multi-hole pattern of the 3M™ Hookit™ Purple Clean Sanding Abrasive Disc 334U does not require hole alignment with the back-up pad.
Better Science for Better Sanding from 3M
The 3M™ Hookit™ Purple Clean Sanding Abrasive Disc 334U carries our Purple designation which indicates the latest 3M technology, greatest performance and highest quality available in an abrasive disc. From its fast-cutting abrasive to its unique spiral-patterned hole design, this disc combines performance, durability and long-lasting efficiency for improved throughput across your entire collision repair operation. It’s another example of what 3M does best: Science. Applied to Life.TM
