With a 3\/4 inch mill diameter and a 3 inch length of cut, this five-flute tool delivers high material removal rates while maintaining surface finish quality. The variable helix geometry reduces harmonic vibration during cutting, extending tool life and improving cut stability. A Duarise coating adds wear resistance and thermal protection, making this end mill well-suited for hardened steels and high-alloy materials. Micrograin carbide construction provides the edge retention required for consistent performance in production environments. Licensed machinists and tool-and-die professionals are the primary installers and users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers, vertical mills, and manual knee mills for slotting, profiling, and peripheral milling operations. It is a single-end, right-hand cutting tool with right-hand flute direction, making it compatible with standard spindle configurations. The 3\/4 inch shank diameter fits standard ER and end mill holders of the corresponding bore size. Its 6 inch overall length accommodates moderate-reach applications without sacrificing rigidity. This tool is appropriate for shop-floor production, tool rooms, and maintenance machining environments working with ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVariable helix design reduces chatter and vibration during aggressive cuts\u003c\/li\u003e\n\u003cli\u003eDuarise coating provides thermal resistance and extended wear life\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate delivers superior edge retention\u003c\/li\u003e\n\u003cli\u003eFive flutes allow higher feed rates compared to standard four-flute designs\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability enables plunge entry into workpieces\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide end mill for CNC and manual milling machines accepting a 3\/4 inch shank end mill holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist familiar with toolholder torque requirements and runout specifications. Ensure the spindle is fully stopped and the machine is powered down before seating or removing the tool from its holder. Use a properly sized collet or end mill holder that matches the 3\/4 inch shank diameter to maintain concentricity. Follow the machine manufacturer guidelines and shop safety protocols when setting cutting parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Duarise\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.55 inches L x 0.55 inches H x 0.45 inches W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.32 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 82011121\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727383494962,"sku":"82011121","price":952.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d47cf2971668ce03f73eb561b2dea357.jpg?v=1788677074","url":"https:\/\/voomisupply.com\/products\/osg-82011121-square-end-mill-3-4-in-5-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
