It features a 1\/2 inch diameter, a 2 inch length of cut, and a 1\/8 inch (0.1250 inch) corner radius that reduces stress concentrations at the cutting edge and extends tool life. The 45-degree high helix geometry promotes aggressive chip evacuation, which is critical when machining soft, gummy materials like aluminum. A Zplus PVD coating provides lubricity and surface protection. This tool is single-end, centercutting, and right-hand cutting with a right-hand flute direction, making it suitable for both roughing and finishing operations on CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThe 83684 is designed for Series H45AL-3 applications targeting aluminum and non-ferrous metals as primary workpiece materials. Secondary workpiece materials include steel, stainless steel, cast iron, high-temperature alloys, and hard materials. The long-length configuration with a 4 inch overall length and straight cylindrical 1\/2 inch shank suits setups requiring extended reach into deep pockets or slots. It is intended for use with high-precision toolholders to maintain TIR within specification. This tool is commonly run by CNC machinists and tool-and-die shops on vertical and horizontal machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in aluminum and non-ferrous applications\u003c\/li\u003e\n  \u003cli\u003e45-degree high helix angle promotes rapid chip evacuation to prevent recutting and built-up edge\u003c\/li\u003e\n  \u003cli\u003eZplus PVD coating provides surface lubricity and thermal protection\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch corner radius reduces edge chipping and improves surface finish at workpiece corners\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge milling and ramp entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eCoarse pitch, 3-flute configuration balances chip load capacity with chip clearance in aluminum\u003c\/li\u003e\n  \u003cli\u003eMaximum TIR of 0.0003 inch supports tight-tolerance finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Series H45AL-3 end mill applications.

Secure the straight cylindrical shank in a high-precision collet or hydraulic toolholder to maintain TIR within the 0.0003 inch maximum. Power down and lock out the spindle before inserting or removing the tool. Verify runout with a dial indicator before commencing cuts, and confirm cutting parameters are appropriate for the workpiece material and machine capability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches (1.0000 inch decimal per attribute data)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0020 to 0.0020 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches (4.0000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: -0.0620 to 0.0620 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\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: Zplus (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees (High)\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\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\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\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: Aluminum, Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, High Temperature Alloy, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0003 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: H45AL-3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.309 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: HELICAL SOLUTIONS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 83684\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51752997749042,"sku":"83684","price":183.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/693fdc420efa1230e2f4a7a78a1081b1_cb0f5aa8-56ca-4285-bde1-8af0d863e288.jpg?v=1788931981","url":"https:\/\/voomisupply.com\/products\/helical-solutions-83684-corner-radius-end-mill-1-2in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
