Built on the Series HS platform, it features a 1\/4 inch cutting diameter, a 1 inch length of cut, and five spiral flutes with a 38-degree helix angle. The AlTiCrN coating provides heat and wear resistance, making this end mill well-suited for cutting harder ferrous and exotic materials at elevated speeds. A variable index geometry helps reduce harmonic vibration during cuts. Machinists and CNC operators in job shops, tool rooms, and production environments install this tool in standard 1\/4 inch collets or end mill holders.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in milling operations on CNC machining centers and manual mills where a 1\/4 inch shank is required. The 3 inch overall length and 1 inch length of cut make it appropriate for moderate-depth slotting, profiling, and peripheral milling applications. The centercutting design allows it to plunge directly into workpiece material. Right-hand cutting direction and right-hand flute spiral are standard for conventional CNC setups. It is a single-end tool, so once the cutting end is worn, the tool is replaced rather than indexed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiCrN coating extends tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eFive-flute spiral design increases feed rate capability over standard four-flute tools\u003c\/li\u003e\n  \u003cli\u003e38-degree helix angle improves chip evacuation and surface finish\u003c\/li\u003e\n  \u003cli\u003eVariable index spacing reduces chatter and harmonic vibration\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry permits direct plunge entry into material\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4 inch shank square end mill compatible with 1\/4 inch collets, shrink-fit holders, and end mill holders used on CNC machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC operator. Secure the shank fully in the holder to the recommended gauge line depth before tightening to avoid runout. Ensure the spindle and machine are at a complete stop before changing tooling.
