Just purchased a horizontal mortising machine. It is an older machine with a cross slide table and a large Jacobs chuck. it is 3 phase and somewhere around 3h.p. powered by a flat belt. What would be the optimal tooling for mortises ? The guy I bought it from just used a brad point drill bit. I have seen suggestions in threads here ranging from end mills to birds mouth bits. What works well in solid woods (hardwood) and does it make a difference what size mortise I am milling ? I plan to use this mostly for mortising table legs and interior/exterior doors. So mostly 1/2'' and possibly 5/8'' mortises.
