Carrying a 1\/4 inch diameter with a 0.03 inch corner radius, this single-end, centercutting tool operates with 3 flutes in a right-hand spiral configuration. The ZrN (zirconium nitride) coating reduces friction and extends tool life in demanding cutting environments. Variable helix and variable index geometry help suppress chatter and improve surface finish at higher feed rates. At 0.07 pounds, it is compact and suited for use in CNC machining centers and milling machines where consistent tolerances are required.\u003c\/p\u003e\n\u003cp\u003eThis end mill is appropriate for production and job-shop milling applications involving aluminum, copper, brass, and similar non-ferrous workpiece materials, consistent with its N1BZ material grade designation from the CoroMill Dura series. The 3\/8 inch length of cut and 3 inch overall length make it well suited for shallow-to-moderate depth profiling, slotting, and contouring operations. Machinists and CNC programmers in aerospace, automotive, and general machining environments will find this geometry appropriate for finishing and semi-finishing passes where corner integrity is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in high-speed milling\u003c\/li\u003e\n  \u003cli\u003eZrN coating reduces built-up edge and extends tool life in non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eVariable helix and variable index design reduces harmonic vibration and chatter\u003c\/li\u003e\n  \u003cli\u003e0.03 inch corner radius protects cutting edge and improves corner durability\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction and cutting orientation compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and production cutting tool for use in standard CNC milling machines and machining centers accepting a 1\/4 inch straight cylindrical shank.

Ensure the machine spindle is fully stopped and powered down before inserting or removing the tool from the collet or end mill holder. Confirm the 1\/4 inch shank seats fully and is secured to the toolholder manufacturer's specified clamping procedure. Verify runout with a dial indicator after installation before beginning a cutting operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.8750 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: 1\/4 inch\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\u003eCoating\u003c\/strong\u003e: ZrN (Zirconium Nitride)\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: 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\u003eVariable Helix\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\u003eMaterial Grade\u003c\/strong\u003e: N1BZ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroMill Dura\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8038671\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51732134232370,"sku":"8038671","price":115.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f601d80b5198f0d9c428a935a395070_c7969bba-8f97-4a30-83e3-5eb3b2f72d4c.jpg?v=1788739590","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-8038671-corner-radius-end-mill-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
