No it just snaps , I go at a slow rpm and then it get in a bind I stop and after a few it snaps , I won't go to fast and just shear the teeth , the hole I have to drill is at a angle how ever , I figured that it's just cheap holesaw , I've maybe drilled 3mm in 4 hrs and I'm always short on cash but that's the beauty of a true done right budget build , I'd rather take time and go slow than slap crap and fix it ever 15 min
