TTS Blanks
I'm going to be making some tool holder blanks at work, problem is the machine and tools have not arrived yet..
from the tormach page I get that its going to be 3/4 shank and 1 1/2 body, but what is the length of the shank and the inside/outside and depth of the top groove that the R8 mates with? please see my crappy attached image. and fill the blanks in if you can, Cheers

Re: TTS Blanks
From the lip on the holder to the top of the shank is 1-3/8". The depth of the recess is not at all critical - 0.05" should be plenty. The shank MUST be 0.750" or LESS to the bottom of the recess, to ensure no interference with the collet. Many/most real Tormach holders have a slight under-cut on the shank below the lip.

The chamfers on the top edge vary depending on the type of holder. Generally, you want the widest chamfer you can get away with, especially for ATC use.

Re: TTS Blanks
I use a lot of 1/8 and 3/16 cutters. I would like to see TTS holders those sizes. I used to have 1/8 and 3/16 CAT 40 holders for my larger machines, so I know it can be done.
