aRM, if you do opt for the 25mm cutter and have a go at modifying the shank as I have done to six cutters (so far) be aware they're pretty hard. You would absolutely need to use good carbide tooling on the lathe. It's a tough application because you need a hard grade to get through the hardness of the tool shank, yet it has to be tough enough to endure the interrupted cut coming across the Weldon flats.
As for a center hole, it's not a traditional 60º one but you DO have a coolant hole that is centered quite exactly. Use that for support, but bring in your live center only after truing it up in the 4-jaw chuck using a dial test indicator on the ground shank to assure it's straight AND true the whole length of the ground shank.
Best of luck,
Ken
