Special flute geometry & variable helix eliminate vibrations
Applications
With a 1/4″ diameter and 3/8″ length of cut, the YG1 UGMF68016 solid carbide square end mill features a stubby profile that enhances rigidity and precision in machining hard materials, minimizing tool deflection. Its 36° helix angle and four-flute design combined with Y-Coating provide an effective balance between chip evacuation and surface finish, ideal for general milling of hardened steels and nickel-based alloys. This combination reduces wear and maintains cutting edge integrity during both roughing and finishing passes. The square end geometry delivers sharp corners without a radius, necessitating careful handling to avoid chipping during interrupted cuts. Because of Y-Coating unsuitability, this tool should not be used on non-ferrous materials to prevent premature failure. It aligns closely with recommended parameters for roughing and finishing hardened steels from 45 to 52 Rc, making it a dependable choice for demanding applications.
