This stub-length, single-end tool features a 0.0313-inch mill diameter with four flutes and a 30-degree right-hand helix for efficient chip evacuation. The TiAlN (titanium aluminum nitride) coating provides thermal resistance and extended tool life in high-speed dry or semi-dry cutting applications. At 1.5 inches overall length with a 0.125-inch straight cylindrical shank, this end mill suits close-tolerance work in tight setups where rigidity and runout control are critical. Micrograin carbide construction supports fine edge retention at elevated cutting speeds.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers, manual mills, and high-speed spindle applications where a small-diameter finishing or slotting tool is required. The stub length and 5\/64-inch length of cut make it appropriate for shallow slot milling, profiling, and engraving operations in tool steel, stainless, aluminum, and similar workpiece materials. It is a direct fit for applications within the OSG 424 series tool family and is typically selected by machinists, tool-and-die technicians, and CNC programmers working with micro-detail features.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0313-inch mill diameter with center-cutting geometry for plunge entry\u003c\/li\u003e\n\u003cli\u003eFour-flute spiral flute design with 30-degree right-hand helix for smooth chip flow\u003c\/li\u003e\n\u003cli\u003eTiAlN coating for heat resistance and extended tool life in dry cutting\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for fine edge retention and dimensional stability\u003c\/li\u003e\n\u003cli\u003eStub length (5\/64-inch length of cut) maximizes rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank with shank diameter tolerance of +0.0000 to -0.0020 inches for consistent toolholder fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production tool within the OSG 424 series.

Ensure the toolholder bore and collet are clean and free of debris before seating the shank; contamination causes runout and premature tool failure. Confirm spindle speed and feed rate are set per the material and coating manufacturer recommendations before engaging the cut. Do not exceed the rated length of cut when plunge milling, as stub-length tools are not intended for deep-cavity work beyond their flute length.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0313 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0020 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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 424\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 424-031211\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737504252210,"sku":"424-031211","price":109.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc28832c8f0d66a7ffca98e89b2b7e53.jpg?v=1788789409","url":"https:\/\/voomisupply.com\/products\/osg-424-031211-square-end-mill-4-flute-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
