3" x 1/4" SPINLOCK Aluminum Oxide Resin Fibre Disc, 80 Grit

Walter SPINLOCK is the quick-change resin fibre disc for weld blending and finishing in tight quarters, and it comes in two grains so you can match it to the job: aluminum oxide for a finer, controlled finish and general cleanup, zirconia alumina where you want it to bite and move metal. Quick-change mounting — a twist on, a twist off, no tooling — which is the point when you are stepping through grits on one weld instead of grinding a flat panel. Grit ladder: 24–36 to take a weld down, 50–60 to blend it, 80–120 to finish. This is the 3" 80 grit disc (fine) in aluminum oxide, for a 1/4" arbor. Priced per disc, sold by the box of 25.
