It features a 0.75 inch mill diameter, a 1.625 inch length of cut, and a 0.06 inch corner radius that reduces edge chipping and extends tool life in aggressive roughing passes. The chipbreaker geometry breaks up chips before they reweld to the cutting edge, a common problem in aluminum. Variable pitch flute spacing dampens harmonics at high spindle speeds. The Nplus PVD coating provides lubricity and heat resistance suited to non-ferrous applications. Designed for use with high-precision toolholders to maintain the 0.0003 inch maximum TIR spec.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for roughing operations in wrought aluminum, cast aluminum, graphite, and non-ferrous metals. It fits standard CNC machining centers and high-speed milling platforms where high material removal rates in aluminum are the primary objective. The single-end, straight-cylindrical shank seats directly into high-precision collet chucks or hydraulic toolholders. The 4 inch overall length and regular-length classification make it a practical choice for most open-pocket and peripheral roughing scenarios in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eChipbreaker geometry reduces chip recutting and heat buildup in aluminum roughing\u003c\/li\u003e\n  \u003cli\u003eVariable pitch flute spacing minimizes chatter at aggressive feed rates\u003c\/li\u003e\n  \u003cli\u003e5-flute configuration supports high chip loads while maintaining chip clearance for non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e0.06 inch corner radius reduces stress concentration at the tool corner and workpiece edge\u003c\/li\u003e\n  \u003cli\u003eNplus PVD coating enhances lubricity and resists built-up edge on aluminum\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry where required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with high-precision toolholders.

Seat the straight-cylindrical shank fully into a clean, high-precision collet chuck or hydraulic toolholder before torquing to the toolholder manufacturer specification. Verify runout does not exceed the 0.0003 inch TIR maximum before beginning a cut. Consult the machine tool and toolholder documentation for proper clamping length and pull-out force requirements before running high-feed toolpaths.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 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: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.06 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Nplus (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\u003eChipbreaker\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Pitch\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Wrought Aluminum, Cast Aluminum, Graphite, Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 to 0.0000 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\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: -0.0620 to 0.0620 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HVAL-C-5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.8 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: 84282\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51727180136754,"sku":"84282","price":537.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0f675a9a2b8a02b0adb4f0b2673bafdc.jpg?v=1788674392","url":"https:\/\/voomisupply.com\/products\/helical-solutions-84282-corner-radius-end-mill-3-4-in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
