Regards a tool-post for the Trens SN32, my TOS S32 has the same Multifix B offered with the SN32 which works very well with 25mm tooling (25×130 is the "standard" holder for that size of toolpost, but it's sometimes easier to use the 32×140 holders for 25mm tools as they're less snug).

I believe the Cross Slide and Top Slide used on the SN32 is the same design as was used on the S32, and only the apron differs between them (on that assembly, there's other major differences).

Whilst it is possible my holders may have been modified by the previous owner to allow them to go lower to get on center with 25mm tools, but it doesn't look like they have; so I suspect Trens is just being conservative in their tech spec's.

I need to clarify this after having a closer look this evening.

The S32 and Multifix B combination works with 25mm tools for me because my 25mm tooling is all CNMG and WNMG, where the cutting edge is below the top face of the holder due to the geometry.

For HSS/Brazed tools which have been ground to use the top of the blank as a cutting edge, or CCMT (and similar) type insert holders, the Multifix holders would need to be modified for that system to work, and 20mm would be the maximum as standard.
