Mine will accept 1 1/4" shank tools

As did the original holder I got with the toolpost, but  25mm shank is plenty big enough for anything I do and I couldn't justify buying big enough material to gouge out 1 1/4" + clearance slot with meat left to support the cutting forces, so I limited myself to 25mm ,

I haven't seen bigger tools needed since my steelworks days where we would sometimes use 2" square section HSS in the big roll turning lathes.
