With a 1-inch (25.40 mm) mill diameter, a 0.120-inch corner radius, and four helical flutes, this tool balances material removal rate with surface finish quality. The FX1 (nACo) coating extends tool life in abrasive and high-temperature cutting environments. The variable helix and variable index geometry reduce harmonic chatter, making this end mill suitable for aggressive roughing passes as well as finish milling in a single tool. A licensed machinist or toolroom technician is the intended installer and operator.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for production and job-shop environments cutting steel, cast iron, stainless steel, superalloys, titanium, and hard materials. The centercutting design allows direct plunge entry without a pre-drilled pilot hole, which simplifies programming on CNC machining centers. With a 2.50-inch length of cut and a 4-inch overall length, the tool suits medium-depth pocketing, slotting, and profiling operations. It is used with standard end mill holders compatible with a 1-inch straight-cylindrical shank ground to h6 tolerance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide substrate for superior hardness and wear resistance in ferrous and hard materials\u003c\/li\u003e\n  \u003cli\u003eFX1 (nACo) coating provides high-temperature oxidation resistance for dry or minimal-coolant cutting\u003c\/li\u003e\n  \u003cli\u003eVariable helix and variable index flute geometry reduce chatter and improve surface finish at higher feed rates\u003c\/li\u003e\n  \u003cli\u003e0.120-inch corner radius protects cutting edge and improves corner strength in pocketing and profiling\u003c\/li\u003e\n  \u003cli\u003eCentercutting construction allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n  \u003cli\u003eSingle-end, straight-cylindrical shank (h6 tolerance) seats securely in end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with end mill holders accepting a 1-inch straight-cylindrical shank.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Verify holder bore cleanliness and shank runout with a dial indicator before committing to a production run, as runout directly impacts tool life and surface finish. Follow the machine tool manufacturer and tooling manufacturer guidelines for speeds, feeds, and depth of cut for the specific workpiece material being cut.\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.50 inches (25.40 mm nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches (101.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.120 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch, h6 tolerance, straight-cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eHelix Style\u003c\/strong\u003e: Variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: FX1 (nACo)\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel; Cast Iron; Superalloys and Titanium; Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1030\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: End Mill Holders\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 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: 121592\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GWS","offers":[{"title":"Default Title","offer_id":52055513268530,"sku":"121592","price":550.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36537447236c65b4546837f96df8cf93_fa5e1a84-a5a0-4317-b203-43040b3a5840.jpg?v=1790037642","url":"https:\/\/voomisupply.com\/products\/gws-121592-corner-radius-end-mill-1-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
