This single-end, 4-flute tool features an 8 mm cutting diameter, an 8 mm length of cut, and a 0.16 mm chamfer width at a 45-degree chamfer angle. The right-hand helical flutes run at a 50-degree high helix angle, and the tool carries a MEGA-64 PVD coating suited for extended tool life in demanding cuts. Centercutting geometry expands the range of entry strategies available to machinists. This tool is installed and used by CNC machinists and toolroom technicians working with hard workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThe 02462690 is well suited for shouldering, slotting, ramp-down milling, helical interpolation, drill milling, and plunging and recessing operations. The extended reach design, with a 16 mm reach length and a reduced neck diameter of 7.40 mm, provides access in confined or deep-feature applications. Its short length-of-cut classification and normal pitch make it appropriate for both roughing and finishing passes in hard material, including hardened steels and similar alloys where MEGA-64 coating performance is most effective.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard material cutting\u003c\/li\u003e\n  \u003cli\u003eMEGA-64 PVD coating provides thermal and abrasion resistance for extended tool life\u003c\/li\u003e\n  \u003cli\u003e45-degree chamfer angle with 0.16 mm chamfer width for consistent edge chamfering\u003c\/li\u003e\n  \u003cli\u003e50-degree high helix angle promotes efficient chip evacuation in deep cuts\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables plunging, ramp-down, and helical interpolation entry\u003c\/li\u003e\n  \u003cli\u003eExtended reach with 7.40 mm neck diameter for access to deep or confined features\u003c\/li\u003e\n  \u003cli\u003eMaximum TIR of 0.01 mm ensures high-precision runout control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification solid carbide end mill in the SECO JHP170 series, intended for use in CNC machining centers and milling machines accepting 8 mm straight-cylindrical shank toolholders with shank tolerance h5.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified CNC machinists or toolroom technicians. The machine spindle must be at a full stop and the control placed in an appropriate safe state before changing tooling. Use a precision collet chuck or hydraulic toolholder sized for an 8 mm shank to maintain runout within the tool TIR specification. Confirm tool overhang and reach requirements before tightening to avoid contact between the toolholder and workpiece fixture during extended-reach operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 8 mm (0.3150 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 8 mm (0.3150 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.16 mm (0.0063 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 55 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Tolerance\u003c\/strong\u003e: h5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 7.40 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 16 mm (0.6299 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 50 degrees (High Helix)\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: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Normal\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\u003eCoolant Through\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\u003eCoating\u003c\/strong\u003e: MEGA-64 (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material (Code H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.020 to 0.040 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.01 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: JHP170\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 02462690\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559729496370,"sku":"02462690","price":148.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/176a716944be3db7b0c3357966e86be2.jpg?v=1786439396","url":"https:\/\/voomisupply.com\/products\/seco-02462690-corner-chamfer-end-mill-8mm-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
