Both the Swiss steel is very hard and heats up fast if you don't over heat the bit it will keep cutting and not burn up or break. When the bit is about to go though you have to go even slower so the bit does not hang up and break. If you are careful you can get one hole with a new bit. The bits i buy come in two packs that way i have a back up.
