General Thread Taps and Dies

HarryMann: A good set of taps and dies can get you out of an awful out of trouble - a critical sapnner 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 and technique to cut into nimonic 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.

I wouldn't buy their 'non-expert' set though.
