Built from cobalt high-speed steel and finished with a TiAlN coating, it delivers heat resistance and extended tool life in demanding cutting environments. The 1 inch cutting diameter and 4 inch length of cut make it well suited for deep-slot and peripheral milling operations. With 5 flutes and a 30-degree helix angle, it balances chip evacuation with surface finish quality. This is a professional-grade cutting tool installed and operated by machinists and toolroom technicians on CNC and manual milling machines.\u003c\/p\u003e\u003cp\u003eThis end mill is appropriate for production and job-shop milling applications where long reach is required. The long overall length of 6.5 inches and 1 inch shank diameter provide rigidity and compatibility with standard ER and milling chucks. The fine pitch flute configuration suits finishing and light roughing passes in steel, stainless, and alloy materials. Right-hand cut and right-hand flute geometry follow standard spindle conventions on most vertical and horizontal milling machines. It is a Series 455 tool from OSG, recognized in tooling specifications for cobalt long-reach end mills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high-speed steel construction for elevated heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life in high-temperature cutting conditions\u003c\/li\u003e\n\u003cli\u003e5-flute fine-pitch design balances chip clearance and surface finish\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle suits a range of ferrous and alloy milling applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute geometry fits standard CNC and manual mill spindles\u003c\/li\u003e\n\u003cli\u003eLong overall length of 6.5 inches accommodates deep-reach milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling selection for milling machines accepting a 1 inch straight shank end mill held in a standard milling chuck or collet system.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the end mill. Secure the 1 inch shank in a properly sized collet or end mill holder torqued to the machine manufacturer's specification. Inspect the TiAlN coating and cutting edges for chips or wear before each use, and replace the tool if edge integrity is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 6.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 455\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: 4560911\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748676993330,"sku":"4560911","price":417.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fbeae5a6b388e4c4e3623abe9a88cd4f.jpg?v=1788896550","url":"https:\/\/voomisupply.com\/products\/osg-4560911-square-end-mill-1in-5-flute-cobalt-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
