I have been working with lines for over 20 years. I have used drills of all brands and types. I have found that the Black Widow brand has always outperformed and outlasted every other brand/type of bit. My least favorite was Milwaukee, Black Widow was my favorite and Wood Owl was somewhere in between. Irvine is ok but not the most reliable. However, this three-pronged wooden owl bite is impressive. This is definitely my new favorite. I can get about 4/5 of the way through a Class 3 Milestone 40 without banging on my 7/16" drive cordless impact drill. money and I can only recommend it.
