The tool features a 3\/8 inch cutting diameter with a 1 inch length of cut and a 2-1\/2 inch overall length, making it suitable for standard-depth slotting, profiling, and peripheral milling operations. The AlCrO-MAX coating provides thermal and oxidation resistance, extending tool life in demanding cutting conditions. With 4 flutes and a 38-degree helix angle, this end mill delivers efficient chip evacuation and a smooth surface finish. It is centercutting capable, allowing direct plunge entry into workpieces. Licensed machinists and CNC operators in job shop and production environments are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThe GWS 310217 is suited for machining a broad spectrum of materials, including cast iron, non-ferrous metals, stainless steel, general steels, high-temperature alloys, and non-metallic materials, corresponding to material codes H, K, M, N, P, and S. Its upcut right-hand flute geometry and right-hand cutting direction make it compatible with standard CNC vertical machining centers and manual knee mills. The 3\/8 inch shank with h6 tolerance fits standard ER collets and end mill holders without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in high-speed applications\u003c\/li\u003e\n  \u003cli\u003eAlCrO-MAX finish provides oxidation and heat resistance, extending tool life\u003c\/li\u003e\n  \u003cli\u003e4-flute, 38-degree helix upcut geometry promotes efficient chip removal and surface finish quality\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge milling directly into the workpiece\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute  -  compatible with standard spindle rotation on CNC and manual mills\u003c\/li\u003e\n  \u003cli\u003eh6 shank diameter tolerance ensures consistent, repeatable tool holding\u003c\/li\u003e\n  \u003cli\u003eSeries 2100 standard length classification for predictable setup geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8 inch shank square end mill compatible with ER collets, end mill holders, and other toolholding systems that accept a 3\/8 inch straight shank.

Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the end mill. Tighten the collet or set screw to the toolholder manufacturer's specified torque. Verify runout with a dial indicator before initiating a cut, particularly in tight-tolerance applications.\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 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: AlCrO-MAX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\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\u003eChipbreaker\u003c\/strong\u003e: No\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\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: H, K, M, N, P, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 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: GWS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 310217\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GWS","offers":[{"title":"Default Title","offer_id":52120701370674,"sku":"310217","price":96.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d0cac41a8e96fc89cc22ba1d973a036_fe35b205-1bd2-4095-b99f-ecfcb6c9baf3.jpg?v=1790083972","url":"https:\/\/voomisupply.com\/products\/gws-310217-square-end-mill-3-8-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
