With a 1-inch cutting diameter, 7 helical flutes, and a 0.09-inch corner radius, this tool delivers smooth surface finishes while protecting edge integrity on difficult workpiece materials. The extra-long configuration features a 4.125-inch length of cut and a 7-inch overall length, making it suitable for deep-pocket and extended-reach applications. The FX3 AlCr coating provides thermal and wear resistance for sustained performance in ferrous and exotic alloy cutting. Shank diameter is 1 inch with an h6 tolerance for precise fitment in standard end mill holders.\u003c\/p\u003e\n\u003cp\u003eThis end mill is engineered for finishing passes on steel, stainless steel, superalloys, titanium, and cast iron. The close-pitch, 7-flute geometry maximizes feed rates during finishing while the high-helix angle promotes chip evacuation and reduces cutting forces. The single-end, right-hand cutting, right-hand flute design is compatible with standard vertical and horizontal CNC machining centers. Typical applications include aerospace components, die and mold work, and precision part machining where tight tolerances and fine surface finish are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-inch cutting diameter with 0.09-inch corner radius for edge protection and finish quality\u003c\/li\u003e\n  \u003cli\u003e7 helical flutes in a close-pitch arrangement for high-feed finishing capability\u003c\/li\u003e\n  \u003cli\u003eExtra-long reach: 4.125-inch length of cut and 7-inch overall length for deep-pocket access\u003c\/li\u003e\n  \u003cli\u003eFX3 AlCr coating rated for steel, stainless steel, superalloys, titanium, and cast iron\u003c\/li\u003e\n  \u003cli\u003eSubmicron solid carbide grade for rigidity and wear resistance in high-temperature cutting\u003c\/li\u003e\n  \u003cli\u003e1-inch straight-cylindrical shank with h6 tolerance for secure holder fitment\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry supports plunge entry; right-hand cut and flute direction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard end mill holders accepting a 1-inch straight-cylindrical shank.

Ensure the machine spindle is fully stopped and powered down before loading or changing tooling. Seat the shank fully into the end mill holder and torque the retention mechanism per the holder manufacturer specification. Confirm runout with a dial indicator before commencing cutting operations, particularly given the extra-long reach of this tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch (25.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.09 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 4.125 inches (104.77 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches (177.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch (25.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: FX3 AlCr\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Close\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\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\u003eChipbreaker\u003c\/strong\u003e: No\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: Steel, Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2215\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.32 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: 312830\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GWS","offers":[{"title":"Default Title","offer_id":52125905060146,"sku":"312830","price":936.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/73a005d5ba50d83229d91438d40f4ca3_01034f51-2f97-44b2-aca0-d55964b93092.jpg?v=1790087998","url":"https:\/\/voomisupply.com\/products\/gws-312830-corner-radius-end-mill-1-in-7-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
