Built to the H1TE series standard, this single-end mill features a 360 variable helix geometry with variable index spacing, which reduces harmonic vibration and chatter during cuts. The AlTiN coating enhances heat resistance and tool life when cutting ferrous and exotic alloys. With a 0.625-inch cutting diameter, 0.75-inch length of cut, and a 3.0-inch overall length, this tool suits general-purpose milling operations where consistent dimensional accuracy and surface finish are required. Licensed machinists and CNC setup technicians are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is engineered for use on steel, stainless steel, cast iron, high-temperature alloys, and hardened materials. The centercutting capability allows plunge operations in addition to peripheral and slot milling. The right-hand cut with right-hand spiral flutes provides standard compatibility with conventional CNC machining centers and manual mills. The 0.625-inch shank diameter fits standard collets and end mill holders without adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and long tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating supports high cutting temperatures and extends wear resistance\u003c\/li\u003e\n  \u003cli\u003eVariable helix (36-39 degrees) with variable index reduces chatter and vibration\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables plunge milling and ramping operations\u003c\/li\u003e\n  \u003cli\u003e4 spiral flutes with right-hand cut and right-hand flute direction\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with 1.3465-inch neck length for reach clearance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on steel (P), stainless steel (M), cast iron (K), high-temperature alloys (S), and hardened materials (H) per ISO material group classifications.
