Built from submicron-grade carbide and coated with AlCrO-MAX for extended tool life, this single-end mill features a 1-1\/4 inch cutting diameter with a 1-1\/2 inch length of cut. The 38-degree helix angle promotes efficient chip evacuation and reduces cutting forces. Four right-hand flutes with an upcut flute direction make it suitable for a wide range of metalcutting and finishing operations. Machinists and tool-and-die professionals are the primary installers and operators of this tooling.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers and manual knee mills where aggressive material removal or finish passes are required. The 1-1\/4 inch square shank seats directly into standard ER or side-lock toolholders at that bore size. The standard length designation and 4-1\/2 inch overall length make it a practical choice for general-purpose pocketing, slotting, and peripheral milling operations in ferrous and non-ferrous metals. The AlCrO-MAX coating provides oxidation resistance at elevated cutting temperatures, extending tool life between regrinds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide substrate for high hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlCrO-MAX coating provides oxidation resistance and extended tool life at elevated temperatures\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eFour right-hand, upcut flutes for general-purpose milling and finishing\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inch square shank compatible with standard toolholders at that bore diameter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard toolholders accepting a 1-1\/4 inch square shank, including ER collet chucks and side-lock holders commonly used in CNC machining centers and manual mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tooling should be installed and operated by qualified machinists familiar with speeds, feeds, and depth-of-cut parameters appropriate for the workpiece material. Ensure the machine spindle is fully stopped and the machine is in a safe state before installing or removing the end mill. Use a torque wrench and the appropriate tool when tightening collet nuts or set screws to avoid shank damage. Inspect the cutting edges and shank for chips or runout before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 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: AlCrO-MAX\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\u003eShank Type\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.49 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: 310621\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GWS","offers":[{"title":"Default Title","offer_id":51971960340786,"sku":"310621","price":819.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d0cac41a8e96fc89cc22ba1d973a036_e4aa333a-b28b-44df-b90e-9ff9e8717dfe.jpg?v=1789959615","url":"https:\/\/voomisupply.com\/products\/gws-310621-square-end-mill-1-1-4-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
