They're strong and I've had no problem breaking, but I can feel it in them. I haven't pushed them and have so far gone through any steel, even a trailer frame, with little effort. Be sure to go from a small pilot hole (and use oil) to larger pilot holes, hold tight too because they can generate a lot of torque. I would buy again.
