Built in the H1TE series, this single-end mill features a 360 variable helix geometry with variable index spacing, reducing harmonics and chatter during aggressive cuts. The AlTiN coating provides thermal resistance and extended tool life when cutting at elevated surface speeds. At 0.375 inches in diameter with a 1-inch length of cut and 3-inch overall length, this tool is sized for finishing and semi-finishing passes in both CNC machining centers and manual mills. It is right-hand cut with right-hand spiral flutes and is centercutting capable, allowing plunge entry into the workpiece. Grade KCPM15 carbide substrate supports the coating for edge strength in interrupted cuts.\u003c\/p\u003e\n\u003cp\u003eThis end mill is engineered for cutting steel, stainless steel, cast iron, high-temperature alloys, and hardened materials, covering ISO material groups P, M, K, S, and H. It is a practical choice for job shops, aerospace component machining, die and mold work, and any application involving difficult-to-machine ferrous and superalloy workpieces. The 0.375-inch shank diameter fits standard ER collet chucks, end mill holders, and shrink-fit toolholders. Its regular-length profile suits the majority of pocket, slot, and profile milling operations without requiring extended-reach clearance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e360 variable helix with variable index reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating delivers high-heat resistance and wear protection in dry or minimal-lubrication cutting\u003c\/li\u003e\n  \u003cli\u003eSolid carbide KCPM15 substrate provides rigidity and edge toughness in interrupted and hardened-material cuts\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flutes with spiral flute geometry for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eSingle-end construction with a 1.562-inch neck length for clearance in shallow-pocket applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide end mill replacement suitable for standard 3\/8-inch end mill holders, ER collet systems, and shrink-fit toolholding used in CNC and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinist or CNC tooling personnel. Ensure the machine spindle is fully stopped and the toolholder is clean and free of runout before seating the shank. Torque collet nuts or set screws to the toolholder manufacturer specifications only.
