I was drilling wood and it really got stuck! When I tried to pull it out with a drill, it wouldn't come out of the drill! I spend a lot of time cheering on a beat. Useless, poorly designed bit! Partly in, but not out. I used a plug-in electric drill and it wasn't as easy to drill deep and split the wood. Do not attempt this with a cordless drill. You want a heavy duty drill with a handle but I don't think it will fit due to its poor design!
