Built from cobalt high-speed steel with a bright finish, it is rated to a H6 thread limit and configured with a plug chamfer featuring 4 to 4.5 chamfered threads for gradual thread engagement. The tap handles 3\/8-24 UNF right-hand threading in through-hole applications. Overall length is 2.9380 inches with a thread length of 0.7520 inches and a tapping depth of 1.2520 inches. Machinists and tool and die professionals use this tap in production and job-shop environments where thread strength and surface finish are critical.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for through-hole threading operations in a wide range of metalworking applications. It is rated for use in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces. The cold-forming process work-hardens the thread form, producing stronger threads compared to cut taps. It is commonly run on CNC machining centers, drill presses, and tapping machines where consistent thread quality across production runs is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-24 UNF right-hand thread form for through-hole applications\u003c\/li\u003e\n  \u003cli\u003eCobalt high-speed steel construction for heat and wear resistance in tough materials\u003c\/li\u003e\n  \u003cli\u003eBright finish with H6 thread limit for controlled fit and dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 4 to 4.5 chamfered threads for gradual thread engagement\u003c\/li\u003e\n  \u003cli\u003eCold-forming design produces no chips, reducing clogging and improving thread strength\u003c\/li\u003e\n  \u003cli\u003eCompatible with alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Ensure the workpiece is securely fixtured and the spindle is properly aligned before tapping. Use a suitable tapping fluid or cutting oil rated for the workpiece material to extend tap life and maintain thread quality. Do not reverse the tap abruptly in hardened or high-alloy materials, as cobalt taps are resistant to heat but can fracture under lateral stress.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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\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\u003eThread Limit\u003c\/strong\u003e: H6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\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\/Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.9380 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.7520 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.2520 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3810 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.2860 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HY-PRO NRT 14001\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: 1400138400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743343280434,"sku":"1400138400","price":44.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e0a7535aeb52c331c9ab34d6077839_7b99bd18-6e83-467b-bfb8-a58de1b3b639.jpg?v=1788845894","url":"https:\/\/voomisupply.com\/products\/osg-1400138400-thread-forming-tap-3-8-24-unf-plug-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
