Built from micrograin solid carbide and coated with AlTiN via a PVD process, this single-end tool delivers both roughing and finishing capability in a compact short-length profile. The 0.01-inch corner radius reduces stress concentrations at the cutting edge, extending tool life in hard and abrasive materials. With a 0.1875-inch diameter, 4 flutes, and a high helix spiral geometry, the 156-11024 is suited for machinists and tool-and-die professionals running aggressive feeds on ferrous and exotic workpieces.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers and milling machines where tight tolerances and clean surface finishes are required. Primary target materials include steel, stainless steel, superalloys, and titanium. The coarse pitch, variable index geometry helps reduce chatter during both slotting and peripheral milling operations. The straight cylindrical shank seats directly into standard toolholders without adapters, making it a straightforward drop-in for shops already running 3\/16-inch shank tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiN PVD coating for high-heat resistance in steel, stainless steel, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for edge retention and rigidity\u003c\/li\u003e\n  \u003cli\u003e0.01-inch corner radius reduces edge chipping and stress at corners\u003c\/li\u003e\n  \u003cli\u003e4-flute, right-hand cut, right-hand spiral with high helix for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eVariable index geometry reduces harmonic chatter during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable  -  allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with straight cylindrical shank for direct toolholder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard cylindrical-bore toolholders accepting a 3\/16-inch shank diameter.
