Built from cobalt high-speed steel with a TiN coating, it handles demanding materials while maintaining edge integrity over extended production runs. The plug chamfer with 4 to 4.5 chamfered threads provides a controlled lead-in for through-hole threading applications. At 2.375 inches overall length with a 0.496-inch thread length and H6 thread limit, this tap is suited for precision threading in ferrous and non-ferrous metals. Machinists and tool-and-die technicians working on production runs or repair work install this tap in CNC machining centers, drill presses, and tapping machines.\u003c\/p\u003e\n\u003cp\u003eThis tap is used for through-hole threading in materials including alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. The thread forming method displaces material rather than cutting it, which produces stronger threads with a work-hardened surface. It is well suited for production threading in both job shop and manufacturing environments where thread quality and tap longevity are priorities. Right-hand thread direction applies to standard UNC 12-24 applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction provides heat and wear resistance in tough alloy and stainless steel applications\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life in high-cycle threading operations\u003c\/li\u003e\n  \u003cli\u003eThread forming design eliminates chip evacuation concerns in through-hole applications\u003c\/li\u003e\n  \u003cli\u003eH6 thread limit ensures consistent tolerance control for standard UNC fits\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 4 to 4.5 chamfered threads delivers controlled thread engagement on lead-in\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement simplifies setup on standard tapping equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Ensure the workpiece is securely fixtured and the tap is aligned axially with the drilled hole to prevent tap breakage. Use a threading fluid or cutting oil appropriate for the workpiece material to reduce forming forces and extend tap life. Always retract the tap fully and inspect for wear after completing production runs in harder materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 12-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 4 to 4.5P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.496 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.933 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.220 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.165 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.2813 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Die Steel, Hardened Steel, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HY-PRO NRT (Series 14001)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 1400123305\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743305957682,"sku":"1400123305","price":39.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e0a7535aeb52c331c9ab34d6077839_9fae7be4-0157-4f9e-863d-c0bb64049036.jpg?v=1788845394","url":"https:\/\/voomisupply.com\/products\/osg-1400123305-thread-forming-tap-12-24-unc-plug-cobalt-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
