Hi Jim
Congrats on your new purchase you have a good selection of kit with it and i couldn't see you needing much more, only disadvantage of using ER32 is the posibility of the tool coming loose and marring the collet, the Clarkson tightens the cutter hard into the rear centre so is not an issue, but i am not fortunate enough to have anything so exotic and it seems to work for Neale.
Happy metal munching
Mike
