Built from M42 cobalt high-speed steel, it delivers heat and wear resistance that outperforms standard M2 HSS in difficult cuts. The tool measures 9\/64 inch (0.1406 inch) in diameter with a 7\/16 inch (0.4375 inch) length of cut, a 3\/8 inch shank diameter, and a 3-1\/8 inch overall length. The 30-degree helix angle and right-hand spiral flutes promote efficient chip evacuation. Machinists and tool-and-die professionals install this tool in standard vertical mills, CNC machining centers, and knee mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, peripheral milling, and plunge cutting in steel, stainless steel, cast iron, and similar ferrous alloys. The double-end configuration provides two usable cutting ends, extending tool life between replacements. The bright, uncoated finish makes it straightforward to inspect for wear. With a regular length profile and a 3\/8 inch shank, it fits standard collet chucks and end mill holders found in most shop setups. It is appropriate for both light production runs and general maintenance machining applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for improved hardness and heat resistance in tough materials\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool, reducing per-cut tooling cost\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix promotes smooth chip flow and reduced chatter\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish for easy wear inspection and compatibility with a wide range of cutting fluids\u003c\/li\u003e\n\u003cli\u003eRegular length profile for standard reach applications in most milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement end mill for use in standard 3\/8 inch collet chucks and end mill holders on vertical mills and CNC machining centers.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank firmly in a matched collet or end mill holder to the appropriate draw-bar torque for your machine type. Verify runout with a dial indicator before beginning a cut, and select cutting parameters appropriate for cobalt HSS tooling in the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 9\/64 inch (0.1406 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/16 inch (0.4375 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/8 inches (3.125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\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 HSS)\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\u003eEnd Type\u003c\/strong\u003e: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/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: 522\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: 5226000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51749010178354,"sku":"5226000","price":77.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e68044e39cc89c270ee7d966699d84f_e7c72fc0-1fb5-47f8-aec0-afe35030e9d2.jpg?v=1788901002","url":"https:\/\/voomisupply.com\/products\/osg-5226000-square-end-mill-9-64-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
