Built with 3 flutes and a 45-degree helix angle, it promotes efficient chip evacuation and reduces built-up edge in sticky materials like aluminum alloys. The cutting edge spans 2 inches of length of cut (LOC), the overall length is 4 inches, and the shank and mill diameter are both 3\/8 inches. A ZrN-based Zplus coating protects the carbide substrate and improves surface finish in non-ferrous applications. This end mill is a single-end tool with a straight shank, right-hand cut, and right-hand flute direction. It is installed by machinists and CNC operators in milling operations requiring tight tolerances and clean finishes.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in vertical and horizontal milling machines and CNC machining centers handling aluminum, brass, copper, and other non-ferrous materials. The 45-degree helix geometry aggressively shears material while keeping cutting forces low, making it well suited for finishing and semi-finishing passes on non-ferrous workpieces. It is center-cutting, allowing plunge entry where the application requires it. Typical use cases include aerospace components, hydraulic manifolds, and general non-ferrous part production where surface finish and tool life are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch diameter with matching 3\/8 inch straight shank for direct collet clamping\u003c\/li\u003e\n  \u003cli\u003e3 flute, 45-degree helix optimized for aluminum and non-ferrous chip evacuation\u003c\/li\u003e\n  \u003cli\u003e2 inch length of cut (LOC) allows deep slot and pocket milling in a single pass\u003c\/li\u003e\n  \u003cli\u003eZplus (ZrN) coating reduces friction and extends tool life in non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry permits plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and wear resistance beyond HSS alternatives\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 3\/8 inch collets and tool holders in CNC machining centers and manual milling machines.

Ensure the machine spindle is fully stopped and the toolholder is clean and free of chips before seating the end mill. Verify runout at the cutting edge after clamping, as excessive runout accelerates wear on carbide tooling. Follow the tool manufacturer and machine builder guidelines for speeds, feeds, and depth of cut appropriate to the workpiece material and rigidity of the setup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\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 (LOC)\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 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\/Finish\u003c\/strong\u003e: Zplus (ZrN)\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\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\u003eWeight\u003c\/strong\u003e: 0.174 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: 03392\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51738788266290,"sku":"03392","price":133.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/abf5f097c803582698c3fff5a30bbe1f_f4fb19cd-078e-4a87-80e4-5533aa61fd87.jpg?v=1788804493","url":"https:\/\/voomisupply.com\/products\/helical-solutions-03392-3-8-in-3-flute-carbide-square-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
