Same Day Shipping YG1 55904TC 3/16″ Size, 1″ LOC, 4 Flute, TiCN Solid Carbide Finishing End Mill

Applications

The YG1 55904TC solid carbide end mill, measuring 3/16″ in diameter with a 1″ length of cut, provides a 5.33x length-to-diameter ratio that enables rigidity and accuracy in deep or confined milling operations. Its 4-flute geometry, combined with a 30° helix angle and TiCN coating, strikes a balance between chip evacuation and surface finish, making it suitable for finishing passes in free-machining steel and cast iron. This combination reduces vibration and improves dimensional accuracy during general milling. This tool closely follows recommended combinations for free-machining steel, supporting moderate speeds and feeds in general milling applications. The TiCN coating enhances wear resistance and diminishes built-up edge formation to extend tool life. Without a corner radius, careful handling is necessary to avoid chipping, especially in interrupted cuts. Avoid using this end mill on heat-resistant superalloys (HRSA ISO S) due to coating unsuitability, which can cause rapid wear. Travers Tool Co provides this model as a dependable choice for machinists working primarily with steel and compatible materials requiring precise finishing.
