Too fine feeds cause excessive wear due to reamer idling the cut. Too coarse feeds ...

Chat OnlineChoice of Reamer: Straight Flute reamers may have advantage in blind holes, since lefthand spiral flutes tend to push swarf forward.

Reaming Speeds: Should be approximately 50% of the speed used for drilling the same material. Faster speeds are generally not an advantage, but may be ...

Chat Online09.10.2008· Something I was told years ago for reaming 2/3 the speed and 3 times the feed of the drill. It has always seemed weird, and no I do not do it. I feed drills up to 20 to 50 ipm depending on the drill, size, and material. Going 60 to 150 ipm on a reamer just does not seem right, but this rule was for bridge ports and conventional lathes.
