It carries a CVD diamond coating that resists the aggressive wear graphite machining imposes on cutting edges. The tool measures 3\/16 inch in diameter with a 0.0200 inch corner radius, a 5\/8 inch length of cut, and a 2 inch overall length. With 4 flutes arranged in a right-hand spiral at a 30-degree medium helix angle, it supports both roughing and finishing operations in a single tool. The centercutting geometry allows plunge entry. This end mill is used by CNC machinists and tooling specialists working in mold shops, electrode manufacturing, and graphite component production.\u003c\/p\u003e\n\u003cp\u003eThe SECO 17000004 is suited for CNC milling of graphite electrodes, mold components, and other abrasive non-metallic workpieces where standard carbide tooling wears prematurely. The 3\/16 inch straight-cylindrical shank fits standard toolholders used on vertical and horizontal machining centers. Its DIACR430 series construction pairs the CVD diamond coating with solid carbide substrate to maintain edge integrity over extended run times in graphite applications. The single-end, normal-pitch configuration keeps setup straightforward for shops running production or prototype graphite work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD diamond coating for extended tool life in graphite and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e0.0200 inch corner radius reduces edge chipping and stress concentrations at workpiece corners\u003c\/li\u003e\n  \u003cli\u003e4-flute right-hand spiral at 30-degree helix angle supports both roughing and finishing passes\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n  \u003cli\u003eTight tolerances: mill diameter +\/-0.0010 inch, corner radius +\/-0.0010 inch, TIR max 0.0005 inch\u003c\/li\u003e\n  \u003cli\u003eSolid carbide substrate in DIACR430 series for rigidity and thermal resistance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard CNC toolholders accepting a 3\/16 inch straight-cylindrical shank.

Ensure the toolholder bore and collet are clean and within specified runout tolerances before seating the shank, as TIR on this tool is rated to a maximum of 0.0005 inch. Graphite dust generated during machining is electrically conductive and a respiratory hazard — confirm dust collection and enclosure ventilation meet applicable shop safety requirements before running. Do not exceed the toolholder manufacturer's recommended pull-out force or clamping torque range for 3\/16 inch shank tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\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: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0200 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees (Medium)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Diamond (CVD)\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Graphite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DIACR430\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0010\/+0.0010 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.00100 to -0.00100 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001\/-0.0004 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: -0.0600\/+0.0600 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 17000004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557389369650,"sku":"17000004","price":203.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d1eaaad4775be7965bcd4cff2b61daf9.jpg?v=1786387123","url":"https:\/\/voomisupply.com\/products\/seco-17000004-corner-radius-end-mill-3-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
