It features a 13\/32 inch (0.4063 inch) cutting diameter, a 1 inch length of cut, and a 1\/2 inch shank diameter, with an overall length of 4-1\/8 inches. Built from M42 cobalt high-speed steel, this double-end mill runs a 4-flute spiral configuration with a 30-degree helix angle and right-hand cut and flute direction. It ships uncoated and is sized as a regular-length tool. Licensed machinists, tool-and-die makers, and CNC mill operators are the primary users of this end mill.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits production and job-shop milling environments where cobalt tooling is preferred over carbide for its toughness and resistance to shock loading. The double-end design extends tool life across repetitive slotting, profiling, and peripheral milling passes on steel, alloy steel, and other ferrous workpieces. The 30-degree helix promotes chip evacuation and smooth cutting action in general-purpose milling setups. It is part of the OSG Series 542 end mill family. Note that this tool is not center-cutting and is not intended for plunge operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two usable cutting ends per tool\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle supports chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral geometry suited for slotting and peripheral milling in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard milling spindle use\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — compatible with most cutting fluids and lubricants without coating compatibility concerns\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and direct-fit tooling option within the OSG Series 542 end mill line.

Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the 1\/2 inch shank fully into the tool holder and torque the set screw or collet nut per the tool-holder manufacturer specification. Because this end mill is not center-cutting, do not use it for direct plunge entry into solid material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 13\/32 inch (0.4063 inches)\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\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/8 inches\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\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\u003eEnd Type\u003c\/strong\u003e: Double End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 542\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: 5429500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51744493175090,"sku":"5429500","price":94.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b4a74c2569de071f53a666a9e01aedd.jpg?v=1788857322","url":"https:\/\/voomisupply.com\/products\/osg-5429500-square-end-mill-13-32-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
