• Recommended Materials: free‑machining plain carbon and alloy steels, cast‑iron, copper or copper alloys, and titanium or titanium alloys

The TiCN‑coated HSS‑E powder metallurgy core delivers a blend of hardness, wear resistance, and toughness that supports reliable performance across demanding milling tasks. The 4‑flute geometry paired with a 30° helix and 12° rake angle promotes efficient material removal and a clean, consistent finish, even at higher feed rates. With a 19 mm length of cut and a compact 69 mm overall length, this tool maintains rigidity in tight pockets and shallow cavities while reaching into moderate depths. Its 10 mm Weldon shank provides a secure, repeatable fit in collets and end mill holders, helping minimize runout and tool deflection. Ideal for workpieces in plain carbon and alloy steels, cast iron, copper alloys, and titanium alloys, this end mill is a versatile choice for general machining, fixture work, and small‑feature milling.
