I have a set of progressive bits from 0.5 to 1.0" all have .5" shank. I use these basically as roughing 'opening up' tools. As much as I try to avert tougher service conditions, the odd time I have experienced them slipping in the chuck jaws. Usually its gummier alloys or taking too bit a bite or rpm/feed not quite right. I keep my older chuck for this & my good chuck for precision work, but I still would prefer not to bugger up the jaws. Do you think a tanged MT driver would assist? I would just need to get one bore size (0.5") and it would fit my MT tail stock.
