Built to the H1TE series specification, this single-end tool features a 0.5-inch mill diameter, 1.25-inch length of cut, and a 45-degree chamfer angle with a 0.0200-inch chamfer width. The four-flute variable-helix geometry reduces chatter and improves chip evacuation. An AlTiN PVD coating increases surface hardness and heat resistance, extending tool life when cutting ferrous and hard materials at elevated feeds and speeds. Licensed machinists and CNC programmers in production shops typically select this tool for finish and roughing passes on tight-tolerance features.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for operations on steel, stainless steel, cast iron, superalloys, titanium, and hard materials (ISO material codes P, M, K, S, H). Its centercutting capability and variable flute design support shouldering, slotting, ramp-down, helical interpolation, drill-mill, plunging, and recessing applications. The straight cylindrical shank with 0.5-inch shank diameter fits standard ER and side-lock toolholders common in vertical and horizontal machining centers. It is cataloged under Kennametal part number H1TE4CH0500R125HA.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-degree chamfer angle with 0.0200-inch chamfer width for precise edge breaking and chamfering\u003c\/li\u003e\n  \u003cli\u003eVariable helix and variable index flute geometry reduces vibration and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating provides elevated heat and wear resistance on ferrous and hard-material cuts\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables plunging, ramp-down, and helical interpolation entry strategies\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute direction with normal pitch for stable chip flow\u003c\/li\u003e\n  \u003cli\u003eSolid carbide substrate in material grade KCPM15 for rigidity in interrupted and continuous cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with steel, stainless steel, cast iron, superalloys, titanium, and hard materials as stated by the manufacturer.
