It drills very smooth, effortless 3/4 inch holes for an auger bit. I was drilling holes in a 6” thick hardwood work bench top. I tried a brad point, Irwin speedbor auger, and the wood owl. The wood owl outperform all of them. I was surprised it did better that the brad but the brad took a lot of force to push without a drill press and wasn't as smooth a cut in the end. I wish I had started with the wood owl. The hex shank is a littler larger than the standard 1/4” but it works as a round shank as well, which is how I used it. Fantastic bit.
