HarryMann: A good set of taps and dies can get you out of an awful lot of trouble - at critical spanner throwing moments!
This one is Silverline's 'expert' set, up to M12. About £30.
Didn't expect it to be much cop actually, but has proved with care to cut threads in semi-nimonic cast steel exhaust manifold, s/s and whatever I've had to use it for really. The tap wrench and die holder aren't a lot of cop, but the taps and dies are def. OK for general use, though not 'Pro' quality, despite the name. All 2nd cut taps, no bottom taps or first taper, but can always buy the odd bottom tap if really needed.
I wouldn't buy their 'non-expert' set though.
