The new design of a not as good as the old version of this auger, splinter has the tendency to get between the blade and the auger and make the drilling impossible, you will need to stop every few seconds to clean this out to be able to keep drilling , very annoying.
Tried to use it on oak and burnt it up. Wood chips built up behind the blade, bent it and that was the end of that. I read reviews, subsequently, stating that this is a chronic problem with the Milwaukee bit and it is not recommended on hardwood. No reflection on the seller. I blame Milwaukee.
