It features a 3\/16-inch diameter, a 0.0300-inch corner radius, and five flutes arranged in a variable-pitch spiral configuration. The APLUS PVD coating improves wear resistance and heat dissipation, extending tool life in demanding cuts. At 2.5 inches overall length with a 9\/16-inch length of cut, this single-end, centercutting tool handles both roughing and finishing passes. It is sized for use with high-precision toolholders and is appropriate for CNC machining centers and manual mills operated by skilled machinists.\u003c\/p\u003e\n\u003cp\u003eThe 45077 is built for milling steel and cast iron as primary workpiece materials, with secondary capability in stainless steel, non-ferrous metals, superalloys, titanium, and hard materials. The variable-pitch flute geometry reduces harmonic chatter during aggressive material removal, making it well-suited for finishing passes that require tight dimensional control. The corner radius helps distribute cutting forces at the tool tip, reducing chipping on hardened or abrasive workpieces. This tool fits standard straight-cylindrical toolholders accepting a 3\/16-inch shank and is part of the HEV-5 series.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eAPLUS PVD coating reduces friction and extends tool life in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e5-flute variable-pitch design reduces chatter during roughing and finishing operations\u003c\/li\u003e\n  \u003cli\u003e0.0300-inch corner radius distributes cutting forces and reduces tip chipping\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge entry directly into the workpiece\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with high-precision toolholders accepting a 3\/16-inch straight-cylindrical shank.

Ensure the spindle is fully stopped and locked before inserting or removing the tool from the toolholder. Use a high-precision collet or shrink-fit toolholder to maintain runout within the specified TIR maximum of 0.0005 inches. Verify tool projection and reach before beginning the cut to avoid interference with workholding fixtures.\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 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/16 inches (0.5625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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: APLUS (PVD)\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\u003ePitch\u003c\/strong\u003e: Variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Non-Ferrous Metal, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0020 to 0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020\/0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HEV-5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.033 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: HELICAL SOLUTIONS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 45077\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51731118457138,"sku":"45077","price":56.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c177c198f98f88cb58c443732cc4a023_e3834d08-33bc-4bab-ba36-7116200ac09a.jpg?v=1788727178","url":"https:\/\/voomisupply.com\/products\/helical-solutions-45077-corner-radius-end-mill-3-16-in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
