With a 3\/32 inch (0.0938 inch) cutting diameter, a 3\/8 inch length of cut, and a 1\/8 inch shank diameter, this tool is built for close-tolerance slotting, profiling, and plunging in tight spaces. The 2-flute geometry with a 30-degree helix angle promotes efficient chip evacuation. Micrograin carbide construction delivers hardness and wear resistance suited to demanding cutting conditions. The uncoated finish makes it a straightforward, cost-effective option for general-purpose milling work. Licensed machinists and CNC operators are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use on vertical mills, CNC machining centers, and manual mills where small-diameter tooling is required. The centercutting design allows both peripheral milling and direct plunge cuts, adding versatility for pocketing and slot work. Its 1-1\/2 inch overall length keeps deflection minimal at this diameter. The Series 402 designation places it within OSG's standard square end mill line. It is well matched to non-ferrous metals, plastics, and softer steels where an uncoated carbide tool performs reliably.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for hardness and edge retention\u003c\/li\u003e\n\u003cli\u003e3\/32 inch cutting diameter with 3\/8 inch length of cut for fine detail work\u003c\/li\u003e\n\u003cli\u003e2-flute spiral geometry with 30-degree helix for effective chip removal\u003c\/li\u003e\n\u003cli\u003eCentercutting design supports direct plunge entry and pocketing operations\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute configuration for standard spindle use\u003c\/li\u003e\n\u003cli\u003eUncoated finish for broad compatibility with common workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank square end mill with a 1\/8 inch shank diameter, compatible with collets and tool holders sized for 1\/8 inch shanks on vertical mills and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Use a calibrated collet or end mill holder rated for the 1\/8 inch shank diameter and verify runout before cutting. Follow the machine manufacturer and tooling manufacturer guidelines for speeds and feeds appropriate to the workpiece material.\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 inch (1.5000 inch)\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: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\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\u003eSeries\u003c\/strong\u003e: 402\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: 0.08 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: 402-0939\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752260862258,"sku":"402-0939","price":25.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/00f818ec4b5c6e0d1c4db5d042cc92ac.jpg?v=1788927013","url":"https:\/\/voomisupply.com\/products\/osg-402-0939-square-end-mill-3-32-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
