The collet is not supposed to extend past the base plate.
Maybe the cutters shaft is too far into the collet?


Much obliged George and dom. I hadn't realised extenders exist. I thought
about not inserting the cutter fully but wasn't too happy about how much
grip would remain.



Whats the lenght of the shaft ?



25mm.
