I will be reaming 6061-T6 90% of the time. I am waiting for reamers to start testing. We will c-dril, drill 31/64, G13 to leave .004 per side, ream .5010. Speed & Feed for the reamer is at 2600rpm and 40ipm, this is in the ball park so we can test. We have a floating tap holder should i G13 the hole to .5000 to get a good start ?
