It features a 5 mm cutting diameter and a 12.5 mm length of cut, with four flutes ground from micrograin carbide for consistent edge integrity. The 43-degree helix angle promotes efficient chip evacuation and reduced cutting forces. A DUROREY coating adds surface hardness and thermal resistance, extending tool life in demanding materials. This end mill ships as a single-end tool and is installed by machinists and CNC operators on vertical machining centers, knee mills, and multi-axis platforms.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finish and semi-finish milling of ferrous and non-ferrous materials in both job-shop and production environments. The 6 mm shank diameter fits standard ER collet chucks and shrink-fit toolholders. The 60 mm overall length keeps the tool compact for close-tolerance work in shallow-to-medium pockets. Right-hand cutting and right-hand flute direction are standard for conventional and climb milling passes. Centercutting geometry allows plunge entry when needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5 mm cutting diameter with 12.5 mm length of cut for controlled depth passes\u003c\/li\u003e\n\u003cli\u003e4-flute configuration in micrograin solid carbide for edge sharpness and rigidity\u003c\/li\u003e\n\u003cli\u003e43-degree helix angle for aggressive chip evacuation and smooth surface finish\u003c\/li\u003e\n\u003cli\u003eDUROREY coating for improved wear resistance and thermal protection\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank solid carbide square end mill with a 6 mm shank diameter, compatible with ER collet systems and other toolholding systems accepting 6 mm round shanks on CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the toolholder manufacturer torque and runout specifications. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Seat the shank to the minimum recommended insertion depth for the collet or chuck in use. Verify runout at the cutting diameter before beginning a production cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5 mm (0.1969 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 12.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 60 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm (0.2362 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 Angle\u003c\/strong\u003e: 43 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: DUROREY\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 8549750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737435898162,"sku":"8549750","price":120.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f792fface2d054f2bdcba680799f2bd.jpg?v=1788788531","url":"https:\/\/voomisupply.com\/products\/osg-8549750-square-end-mill-5mm-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
