Perma-Grit Abrasive Tools harness the remarkable properties of tungsten carbide to create some of the best tools you'll find anywhere for rapidly sanding, shaping, forming and finishing a wide variety of materials with greater efficiency and durability than conventional abrasive tools. With a hardness approaching that of natural diamonds and greater strength than steel and titanium, the tungsten carbide abrasives used in Perma-Grit tools will not load up or break down, cut equally well in any direction, and will outlast sandpaper and most other abrasive tools thousands of times over. Perma-Grit tools are ideal for use on all woods, glass fiber, carbon fiber, Kevlar, Plexiglas, Lexan, Perspex, acrylics, plastics, polystyrene, ceramics, stone, horn, antler and more. Available in coarse grit (US 60/UK 180), medium grit (US 80/UK 220), and fine grit (US 120/UK 320). Made in England.
