3M's fastest cutting, longest lasting abrasive for saving labor costs and improving quality. Perforated sheet roll to easily snap desired sheet size for hand and file applications. Single product for both dust-free and non-dust-free sanding. High-performance Aluminum Oxide. Cuts fast, lasts long, resists loading and leaves a consistent finish. 

Kiss-cut Underscore Technology
The unique kiss-cut underscore technology enables purple abrasive sheet rolls to be easily converted into multiple sheet-length configurations. 

Innovative abrasive construction with clean sanding chevron design combines with a new range of accessories to offer the very best solution for efficient sanding. To achieve maximum performance, 3M has added hundreds of 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 dust extraction. When using a dust extraction system, sheet alignment is not necessary to achieve direct air flow from the panel through the abrasive sheet.
