Built from M42 cobalt high-speed steel, it resists heat and wear at elevated cutting speeds. The 3\/16 inch cutting diameter and stub-length profile make it well suited for short-reach slotting and peripheral milling where rigidity matters. With a 30-degree helix angle, two right-hand spiral flutes, and a bright uncoated finish, this end mill delivers efficient chip evacuation and clean edge geometry straight out of the package. Center-cutting geometry allows for direct plunge entry without a pre-drilled pilot hole.\u003c\/p\u003e\u003cp\u003eThis tool fits production and job-shop environments where tight tolerances and consistent tool life are required. The stub-length configuration reduces deflection in high-feed applications. The double-end design extends usable tool life by providing a second cutting end once the first is worn. It is appropriate for use in steel, stainless steel, cast iron, and other materials within the M42 cobalt working range. The 3\/16 inch shank diameter matches the cutting diameter for direct collet or end mill holder mounting with no adapter required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for improved heat and wear resistance over standard M2 tooling\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two usable cutting ends per tool\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix with two spiral flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable — supports direct plunge milling\u003c\/li\u003e\n\u003cli\u003eStub length (9\/32 inch LOC) reduces deflection in demanding cuts\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use with or without cutting fluid\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard collet chucks and end mill holders accepting a 3\/16 inch shank diameter.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify collet or holder runout is within acceptable tolerance before beginning a cut, as excessive runout accelerates edge wear on small-diameter end mills. Always use appropriate personal protective equipment when handling cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/32 inch (0.2813 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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 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\u003eLength Type\u003c\/strong\u003e: Stub\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 562\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: 5628000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51733196046642,"sku":"5628000","price":56.1,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e51c0883ae59ac876cd481ed8b6d4c5.jpg?v=1788752642","url":"https:\/\/voomisupply.com\/products\/osg-5628000-square-end-mill-3-16-in-2-flute-cobalt-double-end","provider":"Voomi Supply","version":"1.0","type":"link"}
