Need a bigger bit. :-) 0.535" is slightly larger than 17/32" -- I would go with a 9/16" (or 35/64 if you want a super-tight tolerance). You could also use 19/32" or 5/8", if your situation doesn't require any sort of tight tolerances. Pilot hole just needs to be smaller than your final hole -- I'd probably go with a 1/8" or 1/4" (about 1/4th to 1/2 the final diameter). The bit will naturally want to follow any smaller hole. | |
