This auger bit was the opposite of what I expected from an Industrial and Scientific TOOL. It struggled to drill through even the softest of woods, leaving jagged edges and requiring excessive physical force to make any progress. The only positive was the size options available, but with such poor performance, that's hardly worth it .Save your money and invest in a better brand..
I bought 2 of these tools and both broke. One broke off the end of the drill so I could remove it with pliers. the other burst, leaving the end stuck in the project. It actually ruined my project. I do NOT recommend them unless you are drilling soft wood and drilling short holes.
Pros
Two step cut for accurate and clean holes when drilling wood
