I have never used a drawer lock router bit, but I want to use lock joints
on some drawers I'm making for a couple of projects and I need to pick up
an appropriate bit.. But I'm confused by some of the bit specifications.
Shank diameter, at least, is obvious. But what are the implications for
cutting diameter and cutting height? I'm using plain vanilla 3/4" pine
stock. What should I be looking for in a bit?

You want a bit with a cutting height that will let you cut less than stock
thickness of the front. The bit diameter is immaterial, larger lets you
overlap the side with the front to a greater extent.

I'm with Leon on this though, been fiddling with wood for 74 years and have
yet to use a drawer lock bit, too may simple ways to join them; sliding
dovetails are super easy for overlapping fronts, sides butted into a rabbet
for flush ones (for worriers, pin with dowels).
