Built from M42 cobalt high-speed steel and finished with a TiCN (Titanium Carbonitride) coating, this tool delivers improved wear resistance and heat tolerance compared to standard HSS tooling. The single-end design features a right-hand cut with a right-hand helix and measures 3.125 inches in overall length with a 0.375-inch shank diameter. Center-cutting geometry allows for plunge entry as well as peripheral and slot milling. This tool is suited for machinists and toolroom professionals working on ferrous and difficult-to-machine alloys.\u003c\/p\u003e\u003cp\u003eThis end mill is appropriate for use in vertical and horizontal milling machines, CNC machining centers, and manual knee mills. It is well suited for applications involving stainless steel, alloy steels, and other tough ferrous materials where cobalt tooling outperforms standard M2 HSS. The 3\/8-inch shank fits standard collets and end mill holders commonly found in production and toolroom environments. Single-end configuration makes this a practical choice for general-purpose slotting, profiling, and plunge cutting operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for increased red hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and extends tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e4-flute design improves surface finish and feed rate capability\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand helix for standard spindle direction\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 3\/8-inch straight shank\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3\/8-inch shank single-end square end mill compatible with collet chucks, side-lock holders, and shrink-fit toolholders sized for 3\/8-inch shank tooling on milling machines and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerances. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Verify collet or holder cleanliness and proper shank engagement depth before tightening. Consult feeds and speeds reference data appropriate for the workpiece material and machine horsepower before commencing a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Type\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting End\u003c\/strong\u003e: Single End\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 5460408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727206285618,"sku":"5460408","price":91.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1889422db42038a3e988eb1a124c070.jpg?v=1788674714","url":"https:\/\/voomisupply.com\/products\/osg-5460408-square-end-mill-4-flute-3-8-in-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
