Built from micrograin carbide and coated with a ZrN (zirconium nitride) finish, this tool delivers hardness and wear resistance across a range of materials. It features a 1 inch cutting diameter, a 3-3\/8 inch length of cut, and a 6 inch overall length. The 40-degree spiral flute geometry promotes efficient chip evacuation and smooth cutting action. This tool is installed and operated by machinists and CNC programmers in production and job-shop settings.\u003c\/p\u003e\u003cp\u003eThe 109-06446 is suited for end milling, slotting, and profiling operations in ferrous and non-ferrous metals. Its centercutting design allows plunge entry directly into the workpiece. The right-hand cut and right-hand flute configuration is standard for conventional CNC machining centers and manual mills. The Series 109 designation places it within PROMAX's line of high-performance solid carbide end mills intended for general-purpose and high-speed milling applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 inch cutting diameter with a mill diameter tolerance of +0.000 \/ -0.002 inches for consistent sizing\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003eZrN coating provides heat and wear resistance without adding significant edge buildup\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle with spiral flute geometry for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard CNC and manual mill compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill for standard 1 inch collet or end mill holders on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator. Secure the 1 inch straight shank in a properly sized end mill holder or collet chuck, torquing to the machine tool manufacturer's specified clamping values.
