Built on OSGs Series 402 platform, this tool features a 17\/64 inch (0.2656 inch) cutting diameter and a 2-flute spiral configuration with a 30-degree helix angle. The micrograin carbide substrate delivers hardness and edge retention suited to demanding cutting environments. At 0.07 pounds, it is a compact tool with a 5\/16 inch shank diameter and 3\/4 inch length of cut. It is centercutting capable, allowing direct plunge entry. Machinists and tool-and-die professionals are the primary users of this end mill.\u003c\/p\u003e\n\u003cp\u003eThe 402-2656 is intended for general-purpose milling in shop environments handling ferrous and non-ferrous metals. The regular-length geometry and 2-1\/2 inch overall length make it well suited to standard CNC machining centers and manual knee mills with appropriate collet holders. Its right-hand cut and right-hand flute configuration matches conventional spindle rotation on most production machine tools. The uncoated finish makes it a straightforward option for applications where coating compatibility is a consideration or where re-sharpening is part of shop workflow.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for edge retention and rigidity\u003c\/li\u003e\n  \u003cli\u003e17\/64 inch (0.2656 inch) cutting diameter with 3\/4 inch length of cut\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral design with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for applications requiring bare carbide or periodic resharpening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide square end mill for use in CNC machining centers and manual milling machines accepting a 5\/16 inch shank collet or end mill holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or tooling technician. Always power down and lock out the spindle before inserting or removing tooling from a collet or end mill holder. Ensure the shank is clean and fully seated to the correct gauge-line depth before tightening the collet nut or set screw. Verify spindle speed and feed rate against the material being cut before engaging the tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 17\/64 inch (0.2656 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\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: 402\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\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: 402-2656\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731870777650,"sku":"402-2656","price":43.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/860070923eb37d0ef0c99372ad5cd0b8.jpg?v=1788735866","url":"https:\/\/voomisupply.com\/products\/osg-402-2656-square-end-mill-17-64-inch-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
