WTB/WTT/WTB Nmtb 40 AND 30 boring head shanks


1 1/2-18 to fit a large Criterion boring head

I snagged a near new #203 Criterion boring head, but it was on R8 taper and I dont have a machine under power in R8. In fact..Ive got at least 3 R8 shanks to fit if anyone needs one

I need a shank in NMTB 30 and would love in in NMTB 40 as well, so I can run this boring head on my mills

Anyone got a spare?

Ive got a short stubby 1 1/4" shank to fit..but no tooling to hold a shank that big and its not something easily turned down to size


The methodology of the left has always been:

  1. Lie
  2. Repeat the lie as many times as possible
  3. Have as many people repeat the lie as often as possible
  4. Eventually, the uninformed believe the lie
  5. The lie will then be made into some form oflaw
  6. Then everyone must conform to the lie
