I had the pleasure of trying an eskimo light weight auger set up with an 18v Milwaukee I could not believe how light it was and the speed was incredible. Gotta say I am impressed especially since I am usually on foot and have been known to walk for miles sometimes. Has anyone use one of these bits on an actual ion head? May have to make 2 purchases due to cost. I see ion and eskimo has there own versions both basically the same weight. I weighed my ion flute its twice as heavy as the synthetic so any weight I can give up is good. The eskimo I used was awesome, Thanks Roccus.
