I have a project where I need to make short slotted holes in some steel straps and aluminum pieces. I ran across a couple of sliding vices for a drill press and was wondering what the bit would be called or if they even make something like that to use in a drill press. I kinda did a quick search on mill bits, and not sure if they will hold in a chick or not???? I know nothing about milling machines or anything like that. just seeing if I can do the holes in house without spending way too much $$$.
