Built from micrograin carbide and coated with AlTiN via PVD process, it delivers the heat resistance and edge retention needed when cutting steel, stainless steel, cast iron, superalloys, and titanium. The 0.0100-inch chamfer width at a 45-degree chamfer angle breaks edges cleanly while maintaining dimensional accuracy. A variable flute index and 38-degree medium helix combine to reduce chatter and improve chip evacuation during both roughing and finishing operations. Licensed machinists and CNC programmers specify this tool for precision work where surface finish and tool life matter.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling operations across a range of workpiece materials classified under ISO material groups P, M, K, and S. Typical applications include shouldering, slotting, ramp-down entry, helical interpolation, drill mill operations, and plunging and recessing. The super close pitch and single-end, right-hand cutting geometry make it a reliable choice for production environments running steel and stainless components. It carries Series S938 designation and is manufactured to a mill diameter tolerance of +0.0000 to -0.0020 inches, supporting tight-tolerance work in job shops and production cells alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9-flute super close pitch configuration reduces chatter and improves surface finish in steel and stainless\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating provides high-temperature oxidation resistance for dry and semi-dry cutting\u003c\/li\u003e\n  \u003cli\u003eVariable index flutes distribute cutting forces to minimize vibration during aggressive passes\u003c\/li\u003e\n  \u003cli\u003e0.0100-inch chamfer width at 45 degrees for controlled edge breaking and deburring\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate delivers superior wear resistance and edge retention\u003c\/li\u003e\n  \u003cli\u003eSupports roughing and finishing in a single tool across shouldering, slotting, helical interpolation, and plunging\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills accepting a 3\/4-inch straight cylindrical shank. Primary workpiece materials are steel, stainless steel, cast iron, superalloys, and titanium (ISO P, M, K, S). Coolant-through is not supported; external flood or mist coolant is the appropriate delivery method.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC setup technician. The tool must be secured in a precision collet chuck or end mill holder rated for the 3\/4-inch shank diameter to stay within the 0.0005-inch maximum TIR specification. Confirm the spindle and workholding are fully stopped and powered down before tool changes. Do not use this tool for centercutting or direct plunge entry without a helical or ramp-down approach path, as the end geometry is not center-cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.0100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Variable Index\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Super Close\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Operations\u003c\/strong\u003e: Shouldering, Slotting, Ramp-Down, Helical Interpolation, Drill Mill, Plunging and Recessing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: S938\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17002362\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558108594482,"sku":"17002362","price":466.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/653cba67d31243c781982b1072eda2d6.jpg?v=1786403589","url":"https:\/\/voomisupply.com\/products\/seco-17002362-corner-chamfer-end-mill-3-4-in-9-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
