I had to dig 2 holes to install 2 small drain pipes outside my bulkhead. I chose this drill. I found it so helpful. It made digging faster and I saved many times using it. My ground was very hard with rocks and this drill bit was powerful enough to penetrate them all. It was very powerful. I wish it was longer so I can get deeper into the ground. One thing I would suggest is to hold the drill with two hands while running this drill for control (my one-handed fix in my video was for demonstration purposes only). . I also think that for powerful rotations it's better to use an electric drill than a cordless drill.
