Tungaloy has introduced the AddDoFeed small diameter high feed milling cutter series in diameters ranging from 8 to 25 mm (5/16″ to 1″).

AddDoFeed offers high feed milling capability for small parts machining, with cost efficiency and productivity in line with the company’s DoFeed solutions, Tungaloy says.

While solid carbide end mills are a common approach for milling small parts, for slotting or pocketing applications that remove relatively large volume of stock it is unproductive to use these small diameter solid end mills. Due to their low bending stiffness, the tool body cannot sustain the heavy radial force generated when feed is increased in an effort to gain better cycle time.

AddDoFeed uses minimal Size 02 inserts of 4 mm (5/32″) inscribed circle and offers close pitch cutter bodies with high insert-per-diameter density for a small diameter indexable cutter. This allows a 16 mm (5/8″) diameter body to carry four inserts and 25 mm (1″) seven inserts for higher feed rates and increased productivity.

The AddDoFeed02 inserts have the same features of the DoFeed inserts, including double-sided insert with four effective cutting edges, optimal inclination on the cutting edge that enables smooth chip evacuation, and large positive rake that provides light cutting and process security.
