It carries a 0.5-inch cutting diameter with a 0.625-inch length of cut and an extended reach design with a 4.25-inch reach length. The Zplus coating provides lubricity and edge protection suited to aluminum alloys, helping prevent built-up edge and extending tool life in production environments. The 35-degree right-hand helix promotes efficient chip evacuation, which is critical when running aluminum at aggressive feed rates. This tool is installed and run by machinists, CNC operators, and tool-and-die professionals.\u003c\/p\u003e\u003cp\u003eThe 04327 is purpose-built for aluminum milling applications where reduced-neck geometry is required to access deeper features without tool deflection. The extended reach and 4.25-inch reduced neck make it appropriate for mold cavities, pockets, and aerospace or automotive components with significant depth-to-diameter requirements. The straight cylindrical shank seats in standard ER collets, end mill holders, or shrink-fit toolholding. The 6-inch overall length gives clearance for deep-reach setups while the solid carbide construction maintains rigidity.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-flute geometry optimized for aluminum chip load and evacuation\u003c\/li\u003e\n\u003cli\u003eZplus coating reduces friction and inhibits built-up edge in non-ferrous cuts\u003c\/li\u003e\n\u003cli\u003e35-degree right-hand helical flutes for aggressive ramping and slot milling\u003c\/li\u003e\n\u003cli\u003eReduced neck with 4.25-inch reach length enables deep-pocket access\u003c\/li\u003e\n\u003cli\u003eCentercutting design supports plunge entry\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard collet and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a reduced-neck, extended-reach square end mill for aluminum and non-ferrous milling operations; compatible with any standard 0.5-inch straight-shank toolholding including ER collets, Weldon holders, and shrink-fit chucks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm proper insertion depth per the toolholder manufacturer specification, and torque collet nuts or set screws to the toolholder manufacturer guidelines. Verify runout with a dial indicator before full-production cutting to protect both the tool and the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\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: Zplus\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.538 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 04327\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51735236641074,"sku":"04327","price":229.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2b8b3d0b97733bef3a8b25536af6904_c2cfb046-ecfc-415e-95c3-1527ff7349c5.jpg?v=1788770705","url":"https:\/\/voomisupply.com\/products\/helical-solutions-04327-square-end-mill-0-5-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
