You havent said which type of tool post you have on the ML10? If it is the standard cantilever bar with the levelling screw then any tool you can get center hieght will do.
The original tool set was with a 'Boattail' leveling block and the tools had a cutaway iether side to fit it and you just slid the tool forwards and backwards on the boattail to get it level.
10mm tools will work fine and I suggest a mixture of tools with HSS and tipped tools for the task you take on. You have a top speed of 2000rpm I think? so tipped tooling will work fine.
Cutting with tipped tools needs a speed increase of some 150% over HSS.
Enjoy your ML10 and Milling attachment, you did well there!
