The tool measures 1 inch in diameter with a 3.25-inch length of cut, a 1-inch straight-cylindrical shank, and a 6-inch overall length. Nine variable-index flutes with a medium helix and super-close pitch allow this single-end tool to handle both roughing and finishing passes. An AlTiN PVD coating applied over micrograin carbide substrate provides thermal resistance and extended tool life in high-temperature cutting environments. The 45-degree chamfer angle produces a 0.0120-inch chamfer width for consistent edge preparation.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for machining operations that require versatile cutting strategies in a single tool. Supported operations include shouldering, slotting, ramp-down, helical interpolation, drill-mill entry, and plunging and recessing. The right-hand cutting direction and right-hand flute spiral are standard for conventional CNC vertical and horizontal milling centers. The variable index flute spacing reduces harmonic chatter during aggressive cuts, making this tool well-matched for roughing passes on difficult-to-machine alloys as well as final finishing passes where edge quality matters. It is not center-cutting and does not feature through-spindle coolant, so external coolant or air blast should be applied at the cutting zone.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction with AlTiN PVD coating for high-heat resistance in ferrous and superalloy materials\u003c\/li\u003e\n  \u003cli\u003eNine variable-index flutes with super-close pitch for reduced chatter and improved surface finish\u003c\/li\u003e\n  \u003cli\u003e45-degree chamfer angle with 0.0120-inch chamfer width for consistent edge preparation\u003c\/li\u003e\n  \u003cli\u003eSupports shouldering, slotting, ramp-down, helical interpolation, drill-mill, plunging, and recessing in a single tool\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute direction, medium helix — compatible with standard CNC milling spindles\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.0000 to -0.0020 inches for precise fit in collet and shrink-fit toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for machining steel, stainless steel, cast iron, superalloys, and titanium.

The 1-inch straight-cylindrical shank is compatible with collet chucks, hydraulic chucks, and shrink-fit holders — verify runout does not exceed the 0.0005-inch TIR maximum before cutting. Spindle speeds and feed rates must be selected based on workpiece material, depth of cut, and machine rigidity; consult SECO cutting data tables for Series S938 starting parameters. This tool is not center-cutting and cannot be plunged axially without a pre-drilled pilot hole or helical entry strategy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.0120 inches\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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN, PVD Process\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Operations\u003c\/strong\u003e: Roughing and Finishing\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: 2.13 pounds\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: 17002377\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559590265138,"sku":"17002377","price":787.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/653cba67d31243c781982b1072eda2d6_a13f3f7c-2079-4615-8a65-7b20e3d72dc5.jpg?v=1786436104","url":"https:\/\/voomisupply.com\/products\/seco-17002377-corner-chamfer-end-mill-1in-9-flute-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
