These are excellent bits. I bought them to poke holes in plastic buckets. I also used the largest one to drill a hole in a 55 gallon steel barrel to put a faucet in. I used a nail to make a hole for the drill because I don't have the strength to hold the drill still while it's making a hole in the steel.
