Thank you for the tips...
Yes, long time ago I was doing this, however this ACME tapping tool, made for me by a friend, is sort of unique - so I didn't want to ruin it as it is perfectly good for the purpose it was made (Delrin nuts for lead screws, for my 3D printer).
Funny thing, recently I bought on ebay another two lead screws (for lathe, from another supplier as I couldn't find the previous one any more) and those new screws are of slightly larger diameter (older ones were 9.8mm, those are exactly 10mm in diameter) so they do not fit into already made nuts... it seems I will have to bother my friend again...
