One of the best tools I've made is 1/2" cold roll steel drilled out to
accept a
1/4" HSS metal turning bit. Round the nose off at a fairly steep angle and
you
can remove chips right and left.
Four inch depth into the handle is plenty.

Lot of opinions in absolute dimensions. Mine is to put the handle in 75%
of the expected overhang over the rest.
