3tap set

also advice on how to remove the half of a tap stuck. :-(

cheers sam

Got my UNF kit from machine mart for about £25 i think. Do you want to replace the whole kit or just the one part youve broken?

Looks to be available HERE.

You might want to just replace the one you broke, they're about £30 a pop.

Plenty on the Bay of Fleas too, choose a decent one such as Dormer or SKF.

As for removing a broken one Not easy. Has it broken with a piece sticking up to grip
with Mole Grips or similar ? If so gently work it back and forthe till it comes free. If it's
below the surface then youll need a good quality carbide burr and a dremmel
type thing and slowly grind it away.

Quite difficult to remove a broken tap, these tap extractors (http://www.cromwell.co.uk/WLT0752640M?id=uYQcK3zs) do work if you are careful. The usual factory method is to use a spark eroding machine, not really an option for a home workshop.
Good luck!

These guys are helpful and well priced

I've never seen them before, look good

I may have a spare tap you can have. Can you tell me which one broke 1st, 2nd or plug.

you could put a bit of thin wire down each of the 'flutes' or gaps, then twist it out with a screwdriver?
