his Cobalt Step Drill Bits Set can drill screw holes while staying put on the same axis. The large bit has a 3-sided shank and the small bits have hex shank to prevent slip in a drill chuck. It is self-starting and does not need a pilot hole, making it extremely convenient to use. It operates automatically as you drill holes through the materials.
