It features a 1\/4 inch mill diameter, 7-flute geometry with variable index, and an AlTiN PVD coating that provides heat resistance and extended tool life in high-temperature cutting environments. The 45-degree chamfer angle and 0.0030 inch chamfer width make it suitable for both roughing and finishing passes. Licensed machinists and CNC tool room operators install this tool in vertical and horizontal machining centers where edge preparation and multi-operation capability are required.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for shouldering, slotting, ramp-down entry, helical interpolation, drill mill operations, and plunging and recessing applications. The super-close pitch and 7-flute configuration support high-feed strategies in ferrous and exotic alloy workpieces. The single-end, right-hand cutting and right-hand flute direction are standard for conventional CNC milling setups. It is part of the SECO S738 series and carries the manufacturer catalog number S738-0.250-D3-C003.0-Z7.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide substrate for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating rated for steel, stainless steel, cast iron, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003e7-flute variable index geometry supports roughing and finishing in a single tool\u003c\/li\u003e\n  \u003cli\u003e45-degree chamfer angle with 0.0030 inch chamfer width for precise edge preparation\u003c\/li\u003e\n  \u003cli\u003eSuper-close pitch configuration enables aggressive material removal rates\u003c\/li\u003e\n  \u003cli\u003eCapable of shouldering, slotting, helical interpolation, ramp-down, drill mill, and plunging operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers with straight-cylindrical tool holders accepting a 1\/4 inch shank.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before inserting or removing the tool from the holder. Verify runout does not exceed the specified TIR maximum of 0.0005 inches using a dial test indicator before beginning a cut. Consult the machine tool manufacturer and applicable shop standards for proper clamping torque on the collet or tool holder.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.0030 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 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 Configuration\u003c\/strong\u003e: Single End, Non-Centercutting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\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\u003eTIR Maximum\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, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: S738\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: 17002315\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558892568882,"sku":"17002315","price":79.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2ca06f3aa2194be0afdd2f5edac28dd_41b7d128-e299-4dd3-941e-12650de816fd.jpg?v=1786421995","url":"https:\/\/voomisupply.com\/products\/seco-17002315-corner-chamfer-end-mill-1-4-in-7-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
