I turned a collar but the drill itself was not powerful enough to drive it well. My drill is only a hobby one so hopefully yours is of a better qualityEye have the same problem. My pillar drill measures 58 and the pack says it wurks ont 55 or 60 or 65mm. So eye plan to put a strip of 1mm stainless around said pillar drill to make up the difference. May or may not wurk. It will be trial and error.
