    Milling cutters with keyed holes are predominantly for use in horizontal mills. End mills are designed for cutting slots keyways and pockets. Two fluted end mills can be used to plunge into work like a drill. End mills with more than two flutes should not be plunged into the work. Ball end mills can produce a fillet.
