Norton 3X High Performance Hook and Sand Paper Discs with 5 and 8 Universal Vac Hole, Ceramic Alumina, 5" Diameter, Grit P150 Fine (Pack of 10)

Product Description

The Norton 3X Hook & Sand ceramic aluminum oxide coated 5" abrasive disc has a hook-and-loop mounting system for quick disc changes and 8 universal vacuum holes for use with a 5- or 8-hole random orbit sander. Abrasive discs with hook-and-loop attachments don't require mounting tools, don't lose adhesion, and stay tightly attached to the sander for quick and easy grit changes during the project. The ceramic aluminum oxide grit is a self-sharpening abrasive that is harder, tougher, and lasts up to three times longer than standard aluminum oxide, and is recommended for aggressive material removal of wood, metal, fiberglass, and plastic. The abrasive has been treated with a water-based zinc stearate coating that prevents clogs from forming and can be used in wet sanding applications. The abrasive and bond do not contain dyes, so colors will not transfer to the workpiece. The disc has an open coat, which resists clogging and promotes flexibility. Open coat abrasives produce a rougher finish when abrading difficult-to-sand materials because the abrasive grains are spaced farther apart than they are on a closed coat product. The fiber-reinforced A-weight paper combines the flexibility and lightness of paper with the strength of fiber to create an edge tear-resistant backing that delivers a consistent finish.
