It features a 3\/16 inch (0.1875 inch) mill diameter with a matching 3\/16 inch shank diameter, a 3\/4 inch length of cut, and a 2-1\/4 inch overall length. Built from micrograin solid carbide, this end mill delivers consistent edge integrity at small diameters. The 4-flute geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes on a range of workpiece materials. The uncoated finish makes it straightforward to inspect for wear during tool life monitoring.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slot milling, profiling, and peripheral milling in ferrous and non-ferrous materials. Its long-length classification and centercutting capability allow it to plunge directly into the workpiece and reach into deeper features without a pre-drilled entry point. The right-hand cut and right-hand spiral flute configuration match standard spindle rotation on vertical machining centers and CNC mills. Machinists working on small-feature aerospace, mold, or general precision components will find the 3\/16 inch diameter appropriate for tight-tolerance slots and pockets.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin construction for rigid, precise cutting at small diameters\u003c\/li\u003e\n\u003cli\u003e4 spiral flutes with 30-degree helix angle for efficient chip flow and smooth surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eLong-length series for extended reach into deeper features\u003c\/li\u003e\n\u003cli\u003eUncoated surface for straightforward wear inspection and re-coating if needed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit tooling option for standard 3\/16 inch collet or end mill holders on vertical machining centers, CNC mills, and manual knee mills; part of the OSG Series 464 long-length square end mill line.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or CNC setup technician. Confirm the spindle is fully stopped and locked out before seating or removing the tool. Use a properly sized collet or end mill holder rated for the 3\/16 inch shank diameter and torque the retention mechanism per the holder manufacturer specification. Verify runout with a dial indicator after mounting before commencing a cut, as excessive runout accelerates wear at small diameters.\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 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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 (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: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 464\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 464-1875\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730887311666,"sku":"464-1875","price":41.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/871bd514ba96390e08b5d3370cc76136.jpg?v=1788724371","url":"https:\/\/voomisupply.com\/products\/osg-464-1875-square-end-mill-3-16-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
