Can anybody point me to a quality company for new 40 taper and 50 taper toolholders? our 40 taper machines can spin up to 20000 RPM so some toolholders need to be balanced. and we also have thru spindle coolant. Our OKK machine has the "BIG PLUS" spindle and I am told that requires a special holder as well. Any clues would be appreciated

big plus is made by kaiser or big kaiser. We use holders from lyndex, techniks, and command but don't run over 12000 rpm.

I use Iscar. The reps can cut you good deals if you work it right.

Thanks for the input guys, I will ad those sources for our PA to quote on, do you have a "BIG PLUS" spindle? we do not even have a single holder that takes advantage of it. I have 15 years experience with a big 50 taper hog but am new to this smaller OKK 40 taper

no we don't have one just had a sales rep from kaiser here and gave us the sales pitch. From the little I have seen seems like a good theory.
