Making Sheet Sanding Easy
So much technology in one abrasive sheet – our 3M Hookit Clean Sanding Purple Abrasive Sheet Roll 334U cuts fast, lasts long, resists loading and leaves a consistent finish across a wide range of applications. The C-weight paper sheet combines durable, fast-cutting aluminum oxide abrasive, and our unique chevron hole pattern clears particulates away from the surface during dust free and non-dust free sanding. Plus, our Kiss-cut Underscore Technology employs perforations in the sheet that make it fast and easy to create just the right sheet-length configurations to fit power tools, hand file boards and sanding blocks with minimal product waste. The sheets are available in a range of grits for fine featheredging, final sanding or shaping of plastic filler and putty, removing runs, dust nibs and excess orange peel from topcoat finishes and more.
Hard, Tough and Sharp
3M’s fastest cutting, longest 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. This natural mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges, keeping it sharper longer than traditional natural abrasives. Aluminum oxide is suitable for a wide variety of metalworking materials including ferrous alloys. These sheets featuring aluminum oxide abrasive let technicians sand faster to improve productivity and reduce labor costs, and the consistent finish reduces rework.
Our Kiss-Cut Underscore Technology
The unique Kiss-cut Underscore Technology enables technicians to quickly and easily convert Purple abrasive sheet rolls into multiple sheet-length configurations. Sheets are perforated to match a range of accessories. Technicians simply snap the sheet off at the perforations to most closely match the hand or file board for each specific application. This makes for more effective sanding and reduces material waste.</p>
Chevron Hole Configurations
To achieve maximum performance, 3M has added small holes that have been purposely arranged on the sheet in a chevron formation. This configuration of holes allows for optimal particulate removal from the face of the sheet, improving performance when used with or without a dust extraction system. When using dust extraction, sheet alignment is not necessary to achieve direct air flow from the panel through the abrasive sheet, saving time.
Our Hookit Attachment System
3M offers a complete line of hook-and-loop style Hookit sheets for work spaces where adhesive backing may become contaminated by dust, dirt, or flying debris. Hookit sheets conveniently and firmly attach to a hook-and-loop backup hand or file board (sold separately). It’s simple: just slap the sheet on and start sanding. It removes just as cleanly and easily, and can be re-used again and again for the extent of the abrasive life. To ensure easy, fast attachment, the precise multi-hole chevron pattern of the Purple Clean Sanding Abrasive Sheet Roll 334U does not require hole alignment.
The Power of Purple
The 3M Hookit Purple Clean Sanding Abrasive Sheet Roll 334U carries our Purple designation which indicates the latest 3M technology, greatest cost/value and highest quality available in an abrasive sheet roll. From its high-performance aluminum oxide abrasive to its perforated Kiss-cut Underscore Technology to its clean sanding chevron hole pattern and innovative hook and loop attachment, this sheet delivers improved throughput across your entire collision repair operation.
