I got a new to me mill (not a bridgeport unfortunately) that takes r8 tooling. I plan to use it to make small parts for some farm machinery we have. Previously I had a smaller machine taking MT3 collets. I'm glad I had that last year, or I would have been pooched to get my seed into the ground as parts were on a 21 day backorder.
So, my questions are about the collets for the new mill. Is a r8 collet that goes into the spindle better than a r8 to ERxx holder for chatter? How about regular end mill holders? I'm trying to get the least runout to prolong cutter life.
I was hoping to get Hardinge brand collets for the main sizes that I use.
