It measures 1\/8 inch in diameter with a 1\/4 inch length of cut, a 0.03 inch corner radius, and a 1-1\/2 inch overall length. The tool carries a PVD-applied AlTiN coating for heat and wear resistance at elevated cutting temperatures. With 4 helical flutes in a right-hand cutting direction and a medium helix style, it handles both roughing and finishing passes on a single tool. The straight-cylindrical shank measures 1\/8 inch in diameter and fits standard toolholders.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits CNC machining centers and manual mills where close-tolerance work on hard or heat-resistant alloys is required. It is sized for stub-length applications where rigidity and minimal deflection matter more than extended reach. Typical use cases include aerospace component work, die and mold finishing, and precision profiling in stainless steel and high-temperature alloy parts. The 0.03 inch corner radius reduces stress concentration at inside corners and extends tool life compared to a sharp-corner geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiN coating applied via PVD process for oxidation resistance and extended tool life in high-heat cuts\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance in ferrous and exotic alloy materials\u003c\/li\u003e\n  \u003cli\u003e0.03 inch corner radius reduces corner chipping and stress concentration at inside radii\u003c\/li\u003e\n  \u003cli\u003e4 helical flutes with right-hand cut and normal pitch support both roughing and finishing passes\u003c\/li\u003e\n  \u003cli\u003eStub-length geometry minimizes deflection in tight-clearance or short-reach applications\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with h6 shank diameter tolerance for consistent toolholder fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard toolholders accepting a 1\/8 inch straight-cylindrical shank.
