Solid Carbide 4 Flute Square End Mills
Solid carbide 4 flute square end mills are the workhorse of ferrous material machining. The increased core cross-section compared to 2 flute designs provides greater rigidity for higher chip loads, making them ideal for production machining of steel, stainless steel, cast iron, and alloy steels. The 4 flute configuration delivers superior surface finish at higher feed rates.
Available in standard 30-degree helix, variable helix for chatter reduction, long-reach, and extra-long configurations. Premium AlTiN and TiSiN coatings provide thermal stability and wear resistance for extended tool life in high-temperature machining. Corner radius options available for enhanced edge strength in interrupted cuts.
