Built from submicron-grade carbide, it features a 0.5 inch mill diameter, a 0.09 inch corner radius, and four flutes arranged in a variable helix, variable index configuration. This geometry reduces chatter and harmonics during both roughing and finishing passes. The right-hand spiral flutes and centercutting capability allow plunge entry and versatile tool paths. Licensed machinists and CNC operators working in job shops, aerospace, and industrial manufacturing will find this tool suited to demanding material removal applications.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials in a standard-length configuration. It fits into conventional straight-bore end mill toolholders with a 0.5 inch shank. The single-end, straight-cylindrical shank with h6 tolerance provides consistent, repeatable seating in collet chucks and hydraulic toolholders. It performs in both roughing and finishing operations, making it a practical choice for shops that need one tool to handle multiple stages of a part program.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron-grade solid carbide construction for strength and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003e0.09 inch corner radius reduces stress concentration and extends tool life at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eVariable helix and variable index flute geometry minimizes chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design supports direct plunge entry and ramp milling operations\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eShank diameter tolerance h6 for precise fit in collet and hydraulic toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard end mill toolholders accepting a 0.5 inch straight-cylindrical shank.

Ensure the machine spindle is fully stopped and the tool changer is locked out before inserting or removing the end mill. Seat the shank fully into the toolholder to the recommended gauge line and torque the clamping mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a cut, as excessive runout will accelerate edge wear and compromise surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches (12.70 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: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches (38.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches (76.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\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: FX1\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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 Materials\u003c\/strong\u003e: Steel, Cast Iron, Superalloys, 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\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\u003eWeight\u003c\/strong\u003e: 2.4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 121499\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GWS","offers":[{"title":"Default Title","offer_id":51969427931442,"sku":"121499","price":207.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36537447236c65b4546837f96df8cf93_fc307135-4b58-4fbb-a384-44b6c3f91395.jpg?v=1789952253","url":"https:\/\/voomisupply.com\/products\/gws-121499-corner-radius-end-mill-0-5in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
