YG1 55902TN 3/8″ Size, 1-1/2″ LOC, 4 Flute, TiN Solid Carbide Finishing End Mill Brand New

Applications

The YG1 55902TN 3/8″ Size, 1-1/2″ Length of Cut, 4 Flute, TiN Solid Carbide Finishing End Mill provides a balanced combination of rigidity and reach optimized for precision milling in free-machining steel. Its 30° helix angle with four flutes enhances chip evacuation while maintaining cutting strength, supporting smooth finishes and consistent performance. This tool is well matched to recommended combinations for general milling and slotting in low carbon steels, as referenced in Best Combinations. The TiN coating improves wear resistance and lowers friction, working with the 4-flute geometry to sustain cutting efficiency and surface quality. Without a corner radius, this end mill is primarily designed for finishing where sharp edges are preferred but requires careful handling to avoid edge chipping in interrupted cuts. Travers Tool offers this as a dependable choice for applications demanding both precision and durability. It is not recommended for use on HRSA (ISO S) materials due to unsuitability of the TiN coating, which leads to rapid degradation. Although capable of machining cast iron, non-ferrous, and stainless steel to some degree, its main strength is in steel machining. Using it outside intended materials may reduce tool life and performance.
