Built from M42 cobalt high-speed steel, this double-end tool delivers extended tool life in tough materials including hardened steels, stainless, and heat-resistant alloys. The uncoated spiral flute geometry and 30-degree helix angle promote smooth chip evacuation and stable cutting action. With a 7\/32 inch (0.2188 inch) cutting diameter and a 1\/2 inch length of cut, this tool suits detailed profiling and slotting work where tight tolerances are required. It is centercutting, allowing direct plunge entry into the workpiece. Machinists and toolroom technicians in manufacturing, maintenance, and job-shop environments install and run this tool.\u003c\/p\u003e\u003cp\u003eThe OSG 5229200 is suited for milling operations on ferrous metals, stainless steel, titanium, and other difficult-to-machine materials where cobalt tooling outperforms standard high-speed steel. The double-end configuration provides two usable cutting ends, extending the value of each tool. The 3\/8 inch shank diameter fits standard collet chucks, end mill holders, and side-lock holders common in knee mills, CNC machining centers, and manual bridgeport-style equipment. With a 3-1\/8 inch overall length and regular-length classification, this end mill suits general-purpose milling at typical spindle-to-work distances without requiring extended-reach toolholding.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt high-speed steel construction for heat and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle with spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use with cutting fluids in ferrous and non-ferrous applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Series 522 double-end square end mill compatible with 3\/8 inch collet chucks, end mill holders, and side-lock toolholding systems used in vertical milling machines and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eEnd mills should be installed and adjusted by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before changing or seating tooling. Ensure the shank is fully seated in the holder to the recommended engagement depth per the toolholder manufacturer before tightening. Inspect the cutting edges for chips or wear before each use; a damaged cutting edge on cobalt tooling can fracture under load.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/32 inch (0.2188 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble End\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 522\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: 5229200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727650029874,"sku":"5229200","price":74.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2edd29d3456f55c7317aa11bf567a9f8.jpg?v=1788680544","url":"https:\/\/voomisupply.com\/products\/osg-5229200-square-end-mill-7-32-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
