With a 3\/32 inch (0.0938 inch) cutting diameter and a 3\/8 inch length of cut, this tool handles slotting, profiling, and peripheral milling in tight geometries. The 4-flute configuration provides a good balance of chip evacuation and surface finish. A 30-degree helix angle reduces cutting forces and supports smoother engagement in a variety of workpiece materials. This end mill is single-end, uncoated, and built for use in CNC machining centers and manual mills operated by machinists and tool-and-die professionals.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for general-purpose milling in ferrous and non-ferrous materials where tight tolerances and small-diameter tooling are required. The centercutting design allows plunge entry, expanding versatility for applications that require drilling into a workpiece before peripheral passes. The right-hand cut and right-hand flute configuration matches the standard spindle rotation of most CNC and manual milling equipment. It is a practical choice for die makers, mold shops, and precision machining operations working with small-feature geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/32 inch cutting diameter (0.0938 inch) for small-feature and tight-tolerance milling\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e4-flute design balances material removal rate with surface finish quality\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle reduces cutting forces during engagement\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled pilot hole\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 use with cutting fluid in a range of materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or direct-use solid carbide square end mill for CNC machining centers and manual mills requiring a 1\/8 inch shank diameter and 3\/32 inch cutting diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists using an appropriate collet or end mill holder sized to accept a 1\/8 inch shank. Ensure the spindle is fully stopped and locked before tool changes. Confirm runout with a dial indicator after seating to protect tool life and part accuracy. Follow shop-standard feeds, speeds, and coolant practices for solid carbide tooling in the workpiece material being cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/32 inch (0.0938 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 404-0939\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730665111858,"sku":"404-0939","price":27.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/48ac86a9dd73fe7bc57fdcb99aa239be.jpg?v=1788721108","url":"https:\/\/voomisupply.com\/products\/osg-404-0939-square-end-mill-3-32-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
