120Deg Yes
I own a Hex collet block, I made two clean sweeps with that. I milled the flats and drilled the threaded location holes before I did the lathe work to bore and part to size, I used the stub I turned down to fit into the 5C collet to be held with the lathe three jaw chuck.
If you are thinking about making a set this is how I approached it, To me the most important thing I needed to know was what diameter hole was needed to clear the Hex profile on my chuck jaw, I did this by drawing a double scale drawing on paper, I wanted the snuggest fit possible.
Once I had all three pieces made I located them on the chuck jaws for the first time and machined true. Then gave them witness stamps.
Hope this helps .Anthony
