OK. If you plug this into a drill press and turn it on, it will drill a hole in the wood. For that he gets several stars. But. The hole will not be exact. I bought a 13/16" and it was about 20-30k more. Enough to keep it from going through the drill press. The drill bit is larger in diameter than the body and as a result the drill bit wanders and doesn't make a straight And finally if you look at the grooves they are not deep at all and don't remove chips well.Just drill holes for pipe or wire a 13/16 hole there are better options.In the photo it's a red drill bit.
