Built to a stub length profile, it offers a 31\/64 inch (0.4844 inch) cutting diameter with a 5\/8 inch length of cut and a 1\/2 inch shank. The four-flute spiral configuration runs in a right-hand cut and right-hand flute direction with a 40-degree helix angle. A TiCN (titanium carbonitride) coating increases surface hardness and wear resistance, extending tool life in demanding applications. The micrograin carbide substrate supports tight tolerances and consistent performance in high-speed CNC machining centers and manual mills alike. Licensed machinists and tool-and-die professionals are the primary installers.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling in shop environments where close dimensional tolerances are required. The centercutting design allows plunge entry directly into a workpiece, supporting ramping and helical interpolation toolpaths. Its stub length geometry reduces deflection and improves rigidity, making it a practical choice for finishing passes or tight-tolerance work in materials such as steel, stainless, and cast iron. The TiCN finish performs well in dry or minimal-quantity lubrication setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCentercutting design supports direct plunge entry and helical interpolation\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves wear resistance and tool life in hard or abrasive materials\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate maintains edge integrity at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003eStub length profile reduces deflection for improved rigidity and accuracy\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute orientation for standard CNC and manual mill setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tool for 1\/2 inch collet chucks, end mill holders, and hydraulic or shrink-fit toolholders accepting a 1\/2 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the toolholder and spindle are clean and free of debris before seating the shank. Verify runout with a dial indicator after clamping to confirm the shank is within specification tolerances.
