Built from solid carbide and coated with Zplus (ZrN), it runs at the elevated speeds and feeds that aluminum applications demand without galling or built-up edge. The 35-degree right-hand helix clears chips aggressively, keeping the cut clean in deep-pocket and slotting work. The reduced-neck geometry extends reach to 1.375 inches while maintaining rigidity, making it well-suited for cavity work where a standard-length tool cannot clear the wall. Machinists and CNC programmers select this geometry when they need center-cutting capability, right-hand flute direction, and a straight shank for direct collet or end mill holder mounting.\u003c\/p\u003e\u003cp\u003eThis end mill is designed for CNC machining centers and manual mills running aluminum alloys, brass, copper, and other non-ferrous workpiece materials. The reduced-neck, extended-reach configuration is particularly useful in mold work, fixture machining, and aerospace component production where pocket depth exceeds what a standard LOC allows. The 0.5-inch shank diameter fits ER32, ER40, and comparable collet systems as well as Weldon-style holders commonly found in production shops.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in non-ferrous cuts\u003c\/li\u003e\n\u003cli\u003eZplus (ZrN) coating reduces friction and resists aluminum adhesion\u003c\/li\u003e\n\u003cli\u003e35-degree right-hand helix promotes efficient chip evacuation in aluminum\u003c\/li\u003e\n\u003cli\u003eReduced-neck geometry provides 1.375-inch reach beyond the shank\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable — suitable for plunge entry and ramp entry operations\u003c\/li\u003e\n\u003cli\u003eSingle-end design with straight shank for standard collet and holder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in aluminum and non-ferrous machining applications.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully in the collet or holder to the recommended engagement depth per your toolholding system manufacturer. Verify runout with a dial indicator before production cuts, as excessive runout accelerates flute wear and reduces surface finish quality in aluminum.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.375 inches (1-3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Zplus (ZrN)\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\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\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\u003eSeries\u003c\/strong\u003e: End Mills for Aluminum - 3 Flute - Square - 35 deg Helix - Reduced Neck\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.364 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: 04287\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51734605431090,"sku":"04287","price":140.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2b8b3d0b97733bef3a8b25536af6904_5b62adf3-62cb-441a-8cc6-d2ca4cf62f3d.jpg?v=1788763751","url":"https:\/\/voomisupply.com\/products\/helical-solutions-04287-square-end-mill-1-2-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
