I'v got some bits that are similar to forstner bits but they have a long
shank. i think they are for making curved holes. they make a perfect hole
for the press fit contacts. i only use them to drill through the frames of
doors and such because they make a nice hole with no splintering. then i
use a long bell hanger bit to go on through the header or studs.
