With a 0.5000 inch mill diameter and a 1.25 inch length of cut, it delivers precise material removal in ferrous and non-ferrous metals. The 6-flute, right-hand spiral configuration improves chip evacuation and supports higher feed rates compared to lower-flute-count tools. An AlTiN coating provides thermal resistance and extended tool life at elevated cutting temperatures. The 38-degree helix angle promotes smooth cutting action and reduces vibration. This end mill is installed by machinists and tool-and-die professionals working with CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003cp\u003eThe 03007645 is suited for finish and semi-finish milling operations on steel, stainless steel, and hardened alloys where surface quality and dimensional accuracy are critical. The single-end, center-cutting design allows plunge entry and peripheral milling in the same operation. The variable index geometry helps suppress chatter during side milling and slotting passes. A straight-cylindrical 0.5000 inch shank fits standard ER and side-lock toolholders used in production and job-shop environments alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-flute spiral geometry supports higher feed rates and improved surface finish\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides thermal barrier for dry or near-dry machining of hardened steels\u003c\/li\u003e\n  \u003cli\u003e38-degree helix angle reduces cutting forces and vibration\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing suppresses harmonic chatter\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting single-end design enables plunge milling and ramping entry\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate maintains edge sharpness and resists chipping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard OEM-style replacement or direct-use solid carbide end mill in the SECO S638 series, compatible with 0.5000 inch straight-cylindrical toolholders on CNC and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists. Ensure the spindle is fully stopped and the machine is in an e-stop or lockout state before changing tooling. Seat the shank fully in the toolholder to the recommended gauge-line depth and torque the retention mechanism per the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning a production cut to avoid premature edge wear or dimensional error.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: S638\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.060 to -0.060 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.26 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: 03007645\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558917669170,"sku":"03007645","price":144.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9e60b8dd76ed78d0de80234cc8705d8_5d2498af-9cb2-4cd7-a800-a2407c98776a.jpg?v=1786422855","url":"https:\/\/voomisupply.com\/products\/seco-03007645-square-end-mill-1-2-in-6-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
