Built from 3% vanadium high speed steel, it delivers improved wear resistance and edge retention compared to standard M2 HSS. The 4-flute, spiral-flute geometry with a 30-degree helix angle promotes smooth chip evacuation and stable cutting at moderate feed rates. At 11\/16 inches in diameter with a 1\/2-inch shank, this end mill fits a wide range of vertical machining centers, knee mills, and manual milling setups. It is uncoated and centercutting, meaning it can be used for both peripheral milling and plunge operations.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for shop-floor use in toolrooms, job shops, and production environments where vanadium HSS tooling is specified for cost-effective general milling. The regular-length body — 1-5\/8 inches length of cut and 3-5\/8 inches overall length — makes it appropriate for standard-depth slotting, profiling, and pocketing applications where extended-reach tooling is not required. Right-hand cut and right-hand flute orientation are standard for conventional and climb milling on most CNC and manual platforms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3% vanadium high speed steel construction for improved hardness and edge life over standard HSS\u003c\/li\u003e\n\u003cli\u003e4-flute spiral geometry with 30-degree helix for balanced chip flow and surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design supports plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute — compatible with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eUncoated finish allows easy re-sharpening by a qualified tool grinder\u003c\/li\u003e\n\u003cli\u003eRegular-length proportions minimize deflection in standard-depth cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use end mill for standard 1\/2-inch collet or end mill holder setups on vertical machining centers, knee mills, and manual milling machines requiring 11\/16-inch diameter square end tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Secure the 1\/2-inch shank fully into a clean, properly sized collet or end mill holder and torque to the machine manufacturer's specification. Inspect the shank and flutes for damage or runout before use. Always bring spindle to a full stop before changing or adjusting tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 11\/16 inches (0.6875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inches (1.625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inches (0.500 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: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Vanadium High Speed Steel (3% Vanadium)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 5742000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51753005220146,"sku":"5742000","price":74.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/55ba0a357fb2a978f2bd7673f7b46153_59c56099-7894-4d5e-84a7-4ee0619919e4.jpg?v=1788932053","url":"https:\/\/voomisupply.com\/products\/osg-5742000-square-end-mill-11-16-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
