For further information regarding the recommended preparatory diameters, see page 208 - 209. DIN Length · ANSI Shank All ANSI Length · ANSI Shank taps are available in the popular DIN Length · ANSI Shank style. The DIN Length · ANSI Shank configuration allows for added reach capabilities and greater chip clearance. UNF
