Synchroflex T5 timing pulley tooth profile

Synchroflex T5 timing pulley tooth profile

(OP)
Hi, I need to cut a timing pulley - metric synchroflex T5 (5mm pitch).  Reason is - this size only goes up to 60 teeth off the shelf but we need one that is 72 teeth. So I am after the exact profile of the tooth so we can design the cutting tool for it.  I have profile of the belt tooth, but pulley tooth profiles differ slightly in terms of radii on corners etc so we wish to be exact.  We purchased & downloaded ISO 5294-1989 which gives this info but only for Imperial profiles (closest one is XL).  Apparently the metric info is contained in DIN 7221-2, only problem is its only available in hard copy from Germany so it will take a while to arrive & we need it urgently.  Does anyone have the profile of T5 pulley teeth or know where to get it for download?
Thanks.
