greenline is the best one and i have one for over 8 years now and not even bent yet and take a lot of abuse and i run it behind the right angle drill or hevey duty cordless drill [ Dewalt ] and it hold up very nice for me for my money worth.. i did try other brands but they were not even last long for the money worth..
for any more augar bits ,etc go for greenline,, i know it cost little more than others but it will outlast other brands i went thru with it.
merci , marc
sorry for not being here for long time i was busy working
