Built from 3 percent vanadium high speed steel with a TiCN finish, this tool offers improved wear resistance and heat tolerance compared to standard M2 HSS end mills. The 3\/4 inch cutting diameter pairs with a 1-5\/8 inch length of cut and a 30-degree helix angle for efficient chip evacuation and smooth cutting action. With four flutes and a spiral flute geometry, it delivers a balance of material removal rate and finish quality. Machinists and tool and die professionals use this end mill in manual knee mills and CNC machining centers alike.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling in shop and production environments. The centercutting design allows plunge entry directly into workpiece material without pre-drilling. The right-hand cut and right-hand flute configuration is the standard orientation for conventional vertical milling setups. At 3-7\/8 inches overall length with a 3\/4 inch shank diameter, it fits directly into standard ER collets, end mill holders, and Weldon-style tool holders. It is part of the OSG Series 574 regular-length line, making it a straightforward stock replacement for worn or damaged tooling of the same geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3 percent vanadium high speed steel construction for enhanced wear resistance over standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes efficient chip evacuation in slotting and side milling\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eFour spiral flutes balance material removal rate with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute — standard orientation for vertical milling machines and CNC mills\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for standard 3\/4 inch end mill holders, ER collet chucks, and Weldon-style tool holders used in vertical knee mills and CNC machining centers requiring a regular-length 4-flute square end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom personnel. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify tool holder runout with a dial indicator before production use, as excessive runout will accelerate wear on the cutting edges. Tighten set screws or collet nuts to the tool holder specification — overtightening can distort the shank and cause runout issues.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inch (1.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 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\u003eMaterial Grade\u003c\/strong\u003e: 3% Vanadium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: TiCN\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\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5743208\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731864355122,"sku":"5743208","price":101.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8d2bb35b5b85effc0b50dfff39264add.jpg?v=1788735761","url":"https:\/\/voomisupply.com\/products\/osg-5743208-square-end-mill-3-4-in-4-flute-vanadium-hss-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
