Sorry to chirp in...
Con's Tapmatic head only accepts M3-M7 taps; yet he wanted the M9x0.5mm tap to work. Rather than buy a new tapping head (£££), and as the required torque for M9x0.5 threading is low, I got the tap's shank cylindrically ground to a smaller diameter that would fit. It was HSS tool steel, so couldn't be turned on the lathe easily; grinding it was no problem.
Cheers,
Dan
