Although this question was originally asked 9 years ago, Forstner bits
can bore flat bottom holes "at an angle", something other bits have
difficulty in doing.

They make exceptionally clean holes with little or no tear out, too.
Flat-bottom holes are their Forté, though. Think Euro-style door
hardware.

Also filling a flat-bottom hole with hardwood dowel gives endgrain screws a place to bite.
Antique bedframes with captive nuts have to be chisel-mortised, but a modern barrel nut
fits a Forstner-drilled socket nicely.
