It features a 5\/16-inch cutting diameter, a 1\/2-inch length of cut, and a 2-inch overall length in a stub configuration. The two-flute spiral design runs with a 30-degree helix angle and right-hand cut with right-hand flute orientation. Manufactured from micrograin solid carbide and left uncoated, this end mill delivers consistent edge integrity in finish and light roughing passes. It is centercutting, allowing plunge entry directly into the workpiece.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for general-purpose slot milling, profiling, and plunging in ferrous and non-ferrous materials. The stub length profile reduces deflection in short-reach setups on vertical machining centers and manual mills. The 5\/16-inch shank diameter matches the cutting diameter, making it compatible with standard collet chucks and end mill holders of that bore size. Machinists working in job shops, tool rooms, and production environments will find this a reliable choice for precision detail work where rigidity and a clean square shoulder are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for edge hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip evacuation during cut\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute orientation for standard spindle use\u003c\/li\u003e\n\u003cli\u003eStub length profile minimizes deflection in short-reach setups\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for a range of general-purpose milling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or production end mill compatible with standard 5\/16-inch bore collet chucks and end mill holders used on vertical machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Secure the shank fully within a properly sized collet or end mill holder to the recommended engagement depth before tightening. Confirm spindle speed and feed rate are appropriate for the workpiece material before initiating the cut. Inspect the cutting edges for chips or damage before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches (1\/2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\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: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\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\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 412\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\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: 412-3125\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51736537268530,"sku":"412-3125","price":41.34,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/59e45bf77194f4e6840e8b591d3b61ac.jpg?v=1788778519","url":"https:\/\/voomisupply.com\/products\/osg-412-3125-square-end-mill-5-16-inch-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
