It features a 3\/16 inch diameter with a 0.03 inch corner radius, reducing stress concentrations at part corners and extending tool life in demanding cuts. The 4-flute, right-hand spiral geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. An AlTiN coating provides high-temperature oxidation resistance, making this end mill well suited for dry or high-speed machining. Machinists and toolmakers in production and job shop environments install this tool in CNC machining centers and knee mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for long-reach applications with a 1 inch length of cut and a 4 inch overall length, giving it extended reach capability for deep pocket and slot milling. The single-end, center-cutting design allows direct plunging into material. The 3\/16 inch shank diameter matches the cutting diameter for straightforward collet or end mill holder setup. It is used in aerospace, automotive, die-and-mold, and general precision machining where tight corner radii and consistent tolerances are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating supports high-speed and dry machining by resisting heat-related wear\u003c\/li\u003e\n  \u003cli\u003e0.03 inch corner radius reduces chipping at part edges and stress at tool corners\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle with right-hand spiral promotes chip flow and reduces chatter\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry enables direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eLong-reach 4 inch overall length with 1 inch length of cut for deep pocket access\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for CNC machining centers and manual mills accepting a 3\/16 inch diameter end mill holder or collet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Secure the shank fully into a precision collet or end mill holder and torque to the holder manufacturer's specification. Verify runout with a dial indicator before beginning a cut.
