It features a 0.093 inch cutting diameter, a 0.03 inch corner radius, and four right-hand spiral flutes with a 30-degree helix angle. The stub-length geometry keeps the flute section rigid, reducing deflection in miniature milling work. This single-end tool is centercutting, allowing both plunge and peripheral cuts. It ships in a bright, uncoated finish and is suited for both roughing and finishing passes. HVAC, plumbing, and electrical professionals do not typically install this part — it is used by machinists and tool-and-die technicians in precision machine shops.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC machining centers and manual mills for small-feature work in steel, stainless steel, cast iron, aluminum, non-ferrous metals, composites, and wood. The miniature diameter makes it well suited for slotting, profiling, and contouring operations where a full corner radius blend is required. The stub-standard flute length provides additional rigidity compared to extended-reach variants, making it a practical choice for high-speed finishing passes on small components with tight dimensional tolerances.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.093 inch cutting diameter with 0.03 inch corner radius for blended edge geometry\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eFour right-hand flutes with 30-degree helix for smooth chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — suitable for aluminum and non-ferrous applications without coating buildup risk\u003c\/li\u003e\n  \u003cli\u003eStub-standard flute length reduces deflection in miniature milling operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with standard straight-cylindrical toolholders accepting a 0.125 inch shank diameter.
