Made from M2 high speed steel with a bright\/uncoated finish, it features a 5\/16-inch cutting diameter and a 2-flute spiral geometry with a 30-degree helix angle. The 9\/16-inch length of cut and 3\/8-inch shank diameter make it a compact, versatile tool suited for slotting, peripheral milling, and light profiling. It is a single-end, centercutting tool, meaning it can plunge directly into material as well as cut along the side. Machinists, tool-and-die workers, and general machine shop operators are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is appropriate for use on manual knee mills, CNC machining centers, and benchtop milling machines handling light to medium cutting loads. It is well suited to ferrous and non-ferrous workpieces where an uncoated HSS tool provides adequate performance and cost efficiency. The right-hand cutting direction and right-hand flute spiral are standard for conventional and climb milling on most common setups. The 2-flute design provides good chip clearance, making it a practical choice for slotting operations or cutting softer materials where chip evacuation is a priority.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-inch cutting diameter with a 9\/16-inch length of cut for compact milling reach\u003c\/li\u003e\n  \u003cli\u003eM2 high speed steel construction for durability across a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral geometry with 30-degree helix angle for balanced chip flow and cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for general-purpose use without coating wear concerns\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with a 3\/8-inch shank diameter for standard collet or end mill holder fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard single-end square end mill with a 3\/8-inch shank, compatible with collets, end mill holders, and milling chucks sized for 3\/8-inch shank tooling on manual and CNC milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tool operator.
