Sandpaper: Kling-On random orbit discs
Scott Gibson, Contributing Editor
Klingspor uses the European ?P? standard for grading abrasives, more precise than the old American system and producing a more consistent scratch pattern. The abrasive is aluminum oxide that's resin bonded to a heavy paper backing for long life. Unlike discs with a pressure-sensitive adhesive, hook-and-loop discs can be reused a number of times. In December 2004, a 50-pack of 5-in, 8-hole non-loading discs cost about $15.
