YG1 55901TE 1/4″ Size, 1-1/2″ LOC, 4 Flute, YG TiAlN Extreme Solid Carbide Finishing End Mill Authentic

Applications

Designed for detailed milling in steel, the YG1 55901TE solid carbide end mill offers a 1/4″ diameter and 1-1/2″ length of cut, providing a 6.0x length-to-diameter ratio that balances rigidity and extended reach. With 4 flutes, a 30° helix angle, and YG TiAlN Extreme coating, it delivers a combination of strength and efficient chip evacuation that enhances performance in free-machining steel and general milling applications. This tool performs well in slotting and finishing low carbon steels and can handle cast iron, stainless steel, and heat-resistant superalloys as secondary materials, thanks to coating compatibility. Its lack of a corner radius necessitates monitoring for edge chipping during interrupted cuts, as it offers no additional corner wear protection. Users should avoid non-ferrous materials, where TiAlN Extreme coating unsuitability may cause rapid tool wear. The geometry and coating are not suited for soft metals or plastics, where alternative coatings and flute configurations are more appropriate.
