reamer vs core drill whats the difference?

01.08.2018· If you have a cast core to clean up, core drill it to just under finished size, then ream to finished size. Core drills can take a very large chip width (DOC), just like a regular drill. I prefer to keep reamers to a 0.005" chip (radius, each side), although I have taken 0.010" (radius, each side) with a reamer when I didn't have a better-sized drill.
