I have a cheese cutting set project that needs the subject holes drilled (1/4-20). I also need to make a mandrel. I have a chuck with MT that I'm using in the tailstock but my twist drill bits don't want to drill straight. Would a spur point, spade, or forstner bit work best? I have also seen some use center drill bits to start the hole. (I trying to be economical and not buy the $12 mandrel from Rockler ).
Thanks,
Mike
