This is the first time I've used a 1/8" drill bit out of the box to drill an easy hole in a deck board. down around the hole to start the drill bit broke in half (and there wasn't an old screw in the way) I then used my old drill bit to get the job done with no problems.As this was the very first drill press I've tried I am not sure if the other bits in the case work without breaking but when I pull the bits out of the plastic case they really get the thrill I should be careful with them I don't remember me looking at other brands of drill bits that I've used felt the same way. .
