It features a 0.75-inch cutting diameter and a 2.75-inch length of cut, making it well suited for slotting, profiling, and peripheral milling operations. The AlCrO-MAX coating provides thermal and oxidation resistance, supporting extended tool life in demanding cutting environments. With four flutes and a 38-degree helix angle, the 310489 delivers efficient chip evacuation and smooth surface finishes. It is a centercutting design, allowing direct plunge entry into the workpiece. Licensed machinists and CNC mill operators are the primary users.\u003c\/p\u003e\n\u003cp\u003eThe 310489 is rated for use on a wide material range including ferrous steels, cast irons, stainless steels, non-ferrous metals, aluminum alloys, heat-resistant superalloys, and titanium alloys, corresponding to ISO material groups H, K, M, N, P, and S. The upcut right-hand flute geometry with right-hand cut direction makes it compatible with conventional vertical machining centers and CNC milling setups. The 0.75-inch straight shank with h6 tolerance seats securely in standard collet and end mill holders. This is a single-end tool in the GWS Series 2100 lineup, targeted at production and job-shop environments running moderate to high cutting parameters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlCrO-MAX finish for thermal resistance and extended tool life in ferrous and exotic alloys\u003c\/li\u003e\n  \u003cli\u003e38-degree helix angle promotes efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eFour flutes with upcut right-hand flute direction for use on standard CNC vertical mills\u003c\/li\u003e\n  \u003cli\u003eh6 shank tolerance for precise, repeatable fit in collet chucks and shrink-fit holders\u003c\/li\u003e\n  \u003cli\u003eSeries 2100 standard-length design balances reach and rigidity for general-purpose work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on workpiece materials in ISO groups H, K, M, N, P, and S, including hardened steels, cast irons, stainless steels, non-ferrous metals, general steels, and heat-resistant superalloys.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank to full engagement depth in the holder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning the first cut, and confirm cutting parameters match the material group and coating recommendations for AlCrO-MAX coated carbide.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.75 inches (2-3\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Tolerance\u003c\/strong\u003e: h6\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\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Upcut\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Square\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\u003eISO Material Groups\u003c\/strong\u003e: H, K, M, N, P, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.29 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: 310489\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GWS","offers":[{"title":"Default Title","offer_id":52078499234098,"sku":"310489","price":424.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d0cac41a8e96fc89cc22ba1d973a036_50073ecd-6c4b-45d1-a889-ed21661990bd.jpg?v=1790054123","url":"https:\/\/voomisupply.com\/products\/gws-310489-square-end-mill-0-75-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
