Built from micrograin solid carbide and coated with AlTiN via a PVD process, this tool handles steel, stainless steel, cast iron, superalloys, and titanium. The 0.7500-inch mill diameter pairs with a 1.6250-inch length of cut, a 4-inch overall length, and a 0.7500-inch straight-cylindrical shank. A 45-degree chamfer angle and 0.0100-inch chamfer width deliver clean edge breaks on finished workpieces. Variable flute index and a medium helix style at 38 degrees reduce harmonic chatter during both roughing and finishing passes.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC milling operations in job shops, aerospace machining, and general metalworking environments where multi-material capability is required. Its super-close pitch and variable index geometry make it effective for shouldering, slotting, ramp-down, helical interpolation, drill milling, and plunging and recessing operations. It is a single-end, right-hand cutting, right-hand flute tool with no chipbreaker and no coolant-through capability. Short flute length classification keeps it rigid in setups with minimal overhang.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for wear resistance in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating rated for steel, stainless steel, cast iron, superalloys, and titanium (Material Grade Codes P, M, K, S)\u003c\/li\u003e\n  \u003cli\u003e9-flute variable-index geometry at super-close pitch reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003e45-degree chamfer angle with 0.0100-inch chamfer width for consistent edge breaking\u003c\/li\u003e\n  \u003cli\u003eSupports shouldering, slotting, ramp-down, helical interpolation, drill milling, and plunging and recessing\u003c\/li\u003e\n  \u003cli\u003eMaximum TIR of 0.0005 inches and mill diameter tolerance of +0.0000 to -0.0020 inches for precise fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the SECO Series S938 corner chamfer end mill line.

Verify spindle runout against the 0.0005-inch maximum TIR specification before committing to finish passes. This tool is not center-cutting; do not plunge straight down without a pre-drilled entry or helical interpolation path. Follow machine tool manufacturer guidelines for clamping torque and tool projection length to maintain rigidity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.7500 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: 1.6250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.7500 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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Variable Index, Medium Helix\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Super Close\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\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\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\u003eCentercutting\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\u003ePackage Weight\u003c\/strong\u003e: 0.8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.5 x 1.1 x 1.1 inches\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: 17002357\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558341345586,"sku":"17002357","price":384.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b9a3aa87962e5e4ea425c271dca3a81.jpg?v=1786409782","url":"https:\/\/voomisupply.com\/products\/seco-17002357-corner-chamfer-end-mill-3-4-in-9-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
