Quick QC tool post question

Deeplogic,

The AXA tool holders are designed for 3/8" or 1/2" square tooling. However, they will hold 1/4" square cutters or cutter holders if you must. I would recommend that you cut a piece of 1/4" square key stock into lengths equal to the width of the AXA holders for however many holders you have that you wish to load 1/4" square cutters into. Put a spacer into each holder with the actual cutter outboard of it.

But unless you have or plan to buy a 6" lathe, you should plan to eventually phase out the 1/4" tooling.
 
I've found 1/2" shank tool holders to work fine in my AXA on a 12x36 lathe. While the 1/2" is likely overkill, I like the added rigidity as I have to extend my holders out in order to "reach past" the DRO scale that's on the chuck side of the cross slide. This, when I need to work up close to the chuck. Otherwise, I'd likely go with 3/8" shanks.
 
OK. That would be a valid reason for using the usually more expensive 1/2" cutters.
