Built from solid carbide and finished with a ZrN-family Zplus coating, it delivers the hardness and slick surface needed to resist built-up edge in gummy, soft metals. The cutter runs a 40-degree helix angle for aggressive chip evacuation, while a variable pitch (variable index) flute geometry breaks up harmonics and reduces chatter at higher feed rates. Cutting diameter is 0.5 inches with a matching 0.5-inch straight-cylindrical shank. A reduced-neck, extended-reach design gives 2.25 inches of reach length, keeping the tool clear of deep-pocket walls without sacrificing rigidity.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling aluminum billet, extrusions, plate, and cast non-ferrous workpieces in both CNC machining centers and manual knee mills. It performs well in high-speed finishing passes, full-slot roughing in softer alloys, and profiling operations where chip packing and thermal buildup are primary concerns. The 0.625-inch length of cut accommodates standard shoulder depths, while the 4-inch overall length fits most CAT 40, BT 40, and HSK toolholders without extension. Machinists in production shops, tool rooms, and aerospace job shops are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides stiffness and wear resistance in non-ferrous cutting\u003c\/li\u003e\n\u003cli\u003eZplus (ZrN-family) coating reduces aluminum adhesion and extends tool life\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes fast, efficient chip evacuation from the flute gullets\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic vibration and chatter at elevated RPMs\u003c\/li\u003e\n\u003cli\u003eReduced-neck, extended-reach geometry allows 2.25 inches of clearance in deep-pocket applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction; center-cutting capable for plunge entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on aluminum and non-ferrous workpiece materials (primary workpiece material code N). Intended for the HELICAL SOLUTIONS End Mills for Aluminum series featuring 3-flute, square-profile, 40-degree helix, variable pitch, reduced-neck geometry. Fits any toolholder accepting a 0.5-inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or trained CNC operator should install and qualify this tool. Secure the shank in a precision collet or end mill holder and verify runout with a dial indicator before cutting — excessive runout accelerates edge chipping in carbide tooling. Confirm spindle speed and feed rate are programmed for aluminum-grade end mills before engaging the cut; do not use feeds and speeds intended for steel-rated cutters. Coolant-through is not supported on this tool, so flood coolant directed at the cutting zone or high-pressure air blast is recommended to clear chips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eOverall Length\u003c\/strong\u003e: 4 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\u003eReach Length\u003c\/strong\u003e: 2.25 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: 40 degrees\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 (ZrN Family)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\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: Single End, Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum and Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.351 pounds\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: 46331\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51749615436082,"sku":"46331","price":162.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e58b1abe7386f46ee075bf69be3ec513_7f2ba1b1-7ea1-4d8d-8736-f7dc30972ce4.jpg?v=1788908376","url":"https:\/\/voomisupply.com\/products\/helical-solutions-46331-square-end-mill-1-2-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
