              Speedfeed Drills


              The Speedfeed drill is a twin fluted, carbide tipped coolant fed drill. The micro grain solid carbide tip is multi regrindable. The tubular shank is formed and heat treated from high quality chrome molybdenum steel into an overlapping figure of eight cross section.
