Good bit so far
Would RecommendIt’s really hard to give viable review after only one use but that being said, this bit cuts very clean with no chipping I used it in pine and was very please with it for the price.

It doesn't get stuck like the Speedbor or standard Irwin auger bits do. You still need to apply pressure to push the bit through... but much easier in my opinion. Highly recommended. My only complaint is that the shank is round, and...
