We settled for the Iscar for now.
If I recall correctly, they were the IC 907 which we are quite familiar with for our TIP type Threading Insert
"Parameters" - heck Maestro, we don't even know the meaning of the word, technically too complicating a word for us !!!
Tried that fast Speed Lever for 1mm cuts, fed and cut fine. Then switched to our usual slow steady feed rates again for the finish Cuts and, Bob's Your Uncle, a super fine glassy finish with hardly 'threads' showing.
Regretfully, that is the ultimate understanding of our effort and achievement by any given 'parameters'. Really shallow unfortunately.
Don't forget, however, we still do aspire to eventually get "the best" in available Inserts.
Thanks for all the interest and suggestions
