have the drill doctor, love it for smaller bits but have not had such good luck with the bigger ones. maybe its just me its kind of a new tool in the shop but its saved me a few times working late at night when the hardware store is closed. i still like a new bit when drilling precise holes. also as hot rod said i go slow even pulse the trigger on my drill seams to cut way better. as far as the drill press i have that set at the slowest speed all the time. drill bits are always frustrating even with the drill doctor seems your always missing the right one. maybe some day i will figure out how this happens. good luck with your new tool later MO
