Built to Series 3079 standards, it features a 0.5 inch mill diameter, a 1.25 inch length of cut, and a 0.062 inch corner radius that reduces stress concentration at the cutting edge. The variable helix and variable index geometry help break up harmonics and reduce chatter during aggressive cuts. A FIREX coating provides thermal resistance and oxidation protection, extending tool life in abrasive workpiece materials. This is a single-end, right-hand cutting tool with a Weldon flat shank for positive drive in end mill holders.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for both roughing and finishing operations on steel, cast iron, stainless steel, superalloys, titanium, and hard materials. The 3.5 inch overall length and 0.5 inch shank diameter make it a practical choice for standard vertical machining center setups and manual milling machines. It is intended for use with end mill holders and is appropriate for shops running production work or toolroom operations where corner radius geometry is required for part features or edge strength. The Weldon flat shank accommodates side-lock holders common in production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVariable helix and variable index geometry reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eFIREX coating provides high thermal resistance for cutting steel, cast iron, and hard materials\u003c\/li\u003e\n  \u003cli\u003e0.062 inch corner radius with a tolerance of -0.002 to 0.002 inches for consistent edge geometry\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and wear resistance beyond high-speed steel tooling\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank for secure positive drive in side-lock end mill holders\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction with helical flute type suited for both roughing and finishing passes\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 0.5 inch Weldon flat shank.

Ensure the end mill holder is clean and free of chips before seating the Weldon flat shank, and torque the set screw to the holder manufacturer specification. Confirm runout with a dial indicator before beginning a cut, as excessive runout will accelerate corner radius wear and degrade part geometry. Refer to the machine tool builder guidelines and applicable shop safety procedures when setting depth of cut and feed rates.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.062 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.002 to 0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: FIREX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\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: Helical\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 Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: h10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\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\u003eSeries\u003c\/strong\u003e: 3079\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.35 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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9030790127060\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51737035800882,"sku":"9030790127060","price":196.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e9838a85f25371bf684c171bac5711a0_678805f4-bbe7-4288-a71b-ba5d39dbb3a0.jpg?v=1788783454","url":"https:\/\/voomisupply.com\/products\/guhring-9030790127060-corner-radius-end-mill-1-2-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
