That rachet is OK, I would also get a longer one of the same type, very useful, gets your paws out of the road!

how does a ratchet work when your tapping then? i was taught to do 180 turn, then twist back a little to free the swarf then do another 180... if your using a ratchet i presume u just keep winding in till your done

A set like that would might be OK to start you off, but you're going to need to replace the ones you use/break most often.
I bought a comprehensive boxed set from M3 to M14 & replace when needed from MSC Industrial Supply Co..

Hi Wilfy
The ratchet is most useful when cleaning up lots of threads in awkward places. Ypur right on the 180 backwards when cutting new threads. I find the ratchet is also useful for those very awkward places where a normal tap holder cannot go, not easy flipping the ratcket but needs must as they say!!

Morning Guys,
Typically I just buy what I need size wise as and when I need them, normally I would back the tap off a quarter of a turn then do my 180, I think some people use a little lube when tapping, personally I don’t bother.
As been said really I think the ratchet is most useful when doing your second and 3rd tap, not done any work with a bottoming tap to date so not sure a ratchet would make that job any easier.
Can’t say I’ve ever broke any either, would suggest using the right size bore for the tap you want to use.
