I was wondering if maybe forstner bits were used for some

It's handy (for hole steering) to have a variety of Forstners, and for some kinds of dowelling,
they're better than brad point. But, a well-chosen three-size set would be enough
for me. Brad points (or auger bits with an old brace and bit) remove wood faster,
and ride in dowel jigs straighter.
