Built from micrograin solid carbide, it features a 3\/16 inch (0.1875 inch) diameter with a 5\/16 inch length of cut and a 45-degree helix angle that promotes efficient chip evacuation and smooth cutting action. A zirconium nitride (ZrN) coating improves surface hardness and heat resistance, extending tool life in demanding cuts. This is a single-end, stub-length tool with a right-hand cut and right-hand flute direction, suited for CNC machining centers and manual mills where short, rigid tool reach is required.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in professional machine shop environments handling ferrous and non-ferrous materials where a compact, rigid cutting tool is needed. The stub length profile minimizes deflection during aggressive passes. With centercutting capability, it can be used for plunge entry as well as peripheral and slot milling. It is installed and operated by machinists and CNC operators in production and toolroom settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/16 inch cutting diameter with a tight mill diameter tolerance of +0.000\/-0.002 inches for consistent dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eZrN coating for improved hardness and thermal resistance during extended cuts\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle promotes efficient chip flow and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eStub length profile maximizes rigidity and minimizes tool deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flute configuration for standard milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill for standard 3\/16 inch collet or end mill holder tooling systems on CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a compatible 3\/16 inch collet, end mill holder, or shrink-fit holder and torque to the holder manufacturer's specifications. Ensure the shank is fully seated and the holder is clean and free of debris before tightening. Power down and lock out the spindle before changing tooling.
