Built on the Alumigator Series 1026 platform, it features a 1\/4 inch diameter with a 3\/8 inch length of cut and a 37-degree helix angle that promotes efficient chip evacuation and reduces built-up edge. The ZrN (zirconium nitride) coating adds surface hardness and lubricity, extending tool life in abrasive cuts. With three flutes and a right-hand cutting direction, this end mill is suited for finish and semi-finish passes where surface quality matters. It is a centercutting, single-end tool with a submicron carbide grade substrate.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills working with aluminum, plastics, and other non-ferrous workpiece materials. The extended reach design, with a 2-1\/8 inch reach length and a 4 inch overall length, allows access to deeper features and pockets where standard-reach tools cannot follow. The 1\/4 inch shank diameter is compatible with standard ER and shrink-fit collet systems commonly found in production and job shop environments. The upcut flute geometry assists with chip clearing in slot and pocket milling operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eZrN coating provides enhanced lubricity and wear resistance for non-ferrous machining\u003c\/li\u003e\n\u003cli\u003e37-degree helix angle promotes aggressive chip evacuation in aluminum\u003c\/li\u003e\n\u003cli\u003eSubmicron solid carbide substrate for rigidity and resistance to chipping\u003c\/li\u003e\n\u003cli\u003eExtended reach with 2-1\/8 inch reach length for deep pocket access\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute, upcut geometry for clean finishes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use as part of the GWS Alumigator Series 1026 tooling system, optimized for aluminum and non-ferrous milling in CNC machining applications with standard 1\/4 inch collet or toolholder systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and machine is in a safe state before inserting or removing the tool from the collet. Verify collet bore size matches the 1\/4 inch shank diameter to prevent runout or tool pullout during cuts. Follow the machine manufacturer and tooling manufacturer recommended speeds and feeds for the workpiece material being machined.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.375 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: 1\/4 inch (0.25 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2-1\/8 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: 37 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\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: ZrN (Zirconium Nitride)\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: Upcut\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\u003eSeries\u003c\/strong\u003e: 1026 Alumigator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: GWS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 103153\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GWS","offers":[{"title":"Default Title","offer_id":52021772812594,"sku":"103153","price":119.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff7dcd4f68f36ce4f5006367b435e678_7132ba8a-efdc-49e6-8ad7-f0e11b292636.jpg?v=1790012797","url":"https:\/\/voomisupply.com\/products\/gws-103153-square-end-mill-1-4-in-3-flute-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
