Tools4Boards PUCK Swiss diamond disc 400 grit medium is the perfect all-round maintenance and polishing stone for sharp, smooth edges.
Typically used as the third stone in progression from x-coarse to x-fine grit.
Premium Swiss-Made diamond sheet mounted on exceptionally flat precision die-cast aluminum alloy backer.
Exactly the full diameter of each diamond surface contacts the ski or snowboard side edge when PUCK is aligned with the + symbols on any Tools4Boards Switch tool for optimal cutting and polishing efficiency.
PUCK may be hand-held, or quickly fastened to any file guide using a spring clamp and infinitely rotated to use the entire diamond surface.
PUCK is far easier to use than typical rectangular diamond stones as there is no need to angle the stone relative to the length of the edge. Now even novice tuners and kids are able to consistently achieve perfectly sharp and smooth edges.
Dimensions: 40mm diameter X 4mm thick
