With a 0.625-inch mill diameter and a 1.625-inch length of cut, it delivers consistent material removal across a range of workpiece materials. The six-flute configuration provides a higher number of cutting edges per pass, supporting improved surface finish and feed rate capability. An AlTiN coating adds thermal resistance and hardness, extending tool life in high-speed and dry-cutting conditions. The 38-degree helix angle promotes efficient chip evacuation and reduces cutting forces. This end mill is a single-end tool built to exacting dimensional tolerances for use in CNC machining centers and manual milling operations.\u003c\/p\u003e\u003cp\u003eThe 03007651 is suited for side milling, slotting, and profile milling in ferrous and hardened materials where tool rigidity and heat resistance are critical. The straight-cylindrical, 0.625-inch shank accepts standard ER and side-lock toolholders common in production and job-shop environments. Its centercutting design allows plunge entry. The micrograin carbide substrate and variable index geometry make it a practical selection for aerospace, die and mold, and general metalworking applications. Series S638 identifies the product family for reorder and tooling management purposes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSix-flute design supports higher feed rates and improved surface finish compared to four-flute configurations\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides elevated thermal resistance for high-speed and dry-cutting conditions\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes effective chip evacuation and reduces radial cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eMicrograin carbide substrate delivers hardness and edge retention in abrasive and hardened materials\u003c\/li\u003e\n\u003cli\u003eVariable index tooth spacing reduces harmonic vibration during cutting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual mills accepting a 0.625-inch straight-cylindrical shank; fits standard ER collet chucks and side-lock holders of the appropriate bore size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed by a qualified machinist or tooling technician with the machine at full stop and power isolated. Ensure the toolholder bore and shank are clean and free of chips before securing. Follow the toolholder manufacturer's torque and runout specifications when setting tool projection and clamping. Inspect tool geometry and coating condition before each setup to verify the end mill is free of chipping or wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\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\u003eSeries\u003c\/strong\u003e: S638\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.52 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 03007651\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559720223026,"sku":"03007651","price":279.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9e60b8dd76ed78d0de80234cc8705d8_39fa049c-13df-4f11-87d9-62aa1ed1dded.jpg?v=1786439085","url":"https:\/\/voomisupply.com\/products\/seco-03007651-square-end-mill-5-8-in-6-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
