This kind of thing, anyone got any experience with them?
I need to cut some fine internal threads, too fine to use a readily available tap (10 and 18mm at 0.7mm pitch off the top of my head) and too fiddly for me to grind my own HSS bit.
Are these things all over eBay worth getting? I only need one of each size in aluminium and in brass so my other option would be make a couple of taps - I am leaning towards this idea as I've never cut an internal thread on a lathe before and I don't want to bugger it up.
