We searched a very long time for a good quality, economically priced dado stack. This is the one! Two 200mm x 24T outer blades have blank spaces between the teeth to accept chipper blades. Five chippers are supplied in the following thicknesses: 2 x 9/64" (3.5mm), 2 x 5/32" (3.8mm) and 1 x 3/32" (2.28mm). This configuration allows you to cut dadoes from 6.4mm to 22mm. Bore for all blades is 5/8". Shims included. This type of tool should be used only by experienced machinists. Sturdy aluminium storage case included.
