Built from M42 cobalt high-speed steel, this tool delivers strong wear resistance and heat tolerance compared to standard HSS tooling. It features a 3\/4 inch cutting diameter, a 1-5\/8 inch length of cut, and a 30-degree right-hand spiral flute geometry. The uncoated finish is suitable for applications where re-sharpening is routine. Three flutes provide a balance of chip clearance and rigidity, making this mill well suited for profiling, slotting, and side milling operations in shop and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in vertical machining centers, knee mills, and manual or CNC milling machines where a 3\/4 inch shank is the standard toolholder bore. The double-end design extends tool life by providing two usable cutting ends on a single body. At 5-5\/8 inches overall length with a regular-length classification, this tool fits standard tool length requirements without extended-reach concerns. Machinists and toolroom operators performing general-purpose milling in steel, stainless, and cast iron will find this configuration a reliable choice within the OSG Series 532 line.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\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 cutting ends per tool, reducing per-edge cost\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle with right-hand cut and right-hand flute orientation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge entry into workpiece\u003c\/li\u003e\n\u003cli\u003eSpiral flute configuration promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eUncoated finish supports easy re-sharpening in toolroom settings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in milling machines and machining centers accepting a 3\/4 inch straight shank toolholder.

Secure the shank fully in a collet or end mill holder to the minimum recommended grip depth before operation. Confirm spindle speed and feed rate are set per the material being machined before engaging the cut. Inspect both cutting ends for damage before use and after re-sharpening.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-5\/8 inch (5.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\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\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 532\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: 5323100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51736949326130,"sku":"5323100","price":204.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e3e761c140c17a6892d784ccf418b9a.jpg?v=1788782279","url":"https:\/\/voomisupply.com\/products\/osg-5323100-square-end-mill-3-4-in-cobalt-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
