Built on GUHRING's Series 3078 platform, it features a 1\/2 inch cutting diameter, a 1-1\/4 inch length of cut, and four flutes with a 40\/42 variable helix angle. The FIREX coating provides elevated heat resistance and wear protection, extending tool life in ferrous and non-ferrous materials. With a 1\/2 inch shank diameter and a 3-1\/2 inch overall length, the tool fits standard collet and end mill holders. Right-hand cutting geometry makes it suitable for conventional milling setups on CNC machining centers and manual mills. Machinists and tool-and-die professionals are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for side milling, slotting, and profiling operations in production and job-shop environments. The variable helix design reduces chatter and harmonics during aggressive cuts, making it effective on harder steels, alloys, and stainless materials. The corner chamfer end type provides added edge strength at the cutting tip, which reduces chipping during interrupted cuts or entry into hardened workpieces. It is a single-end tool, so the full cutting geometry is concentrated at one end for maximum rigidity. Typical applications include die-making, fixture fabrication, and precision part production where tight tolerances and surface finish quality are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance across a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eFIREX coating delivers high-temperature oxidation resistance and reduced friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e40\/42 variable helix angle reduces vibration and chatter during deep side milling and profiling\u003c\/li\u003e\n  \u003cli\u003eCorner chamfer end type strengthens the cutting tip for use in interrupted cuts and hard materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard CNC and manual milling spindles\u003c\/li\u003e\n  \u003cli\u003eSingle-end design concentrates mass behind the cutting zone for improved tool stiffness\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard production end mill for use in 1\/2 inch collet chucks, end mill holders, and hydraulic toolholders on CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Ensure the spindle is fully powered down and locked before inserting or removing the tool from any holder. Verify collet size and holder bore match the 1\/2 inch shank diameter before clamping. Follow shop-standard runout checks after installation to confirm concentricity before beginning a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40\/42 variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Chamfer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3078\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: 23241600\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: 9030780127000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51730431770930,"sku":"9030780127000","price":163.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/be5fa771cc3e4ebe7bf075c70a0bd6f1_76380233-e4b0-487b-b9e7-9e72e2c98230.jpg?v=1788717343","url":"https:\/\/voomisupply.com\/products\/guhring-9030780127000-square-end-mill-1-2-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
