Part of the EXOPRO XPF-OIL series, it is built from cobalt high-speed steel and coated with TiCN for improved wear resistance and lubricity under demanding conditions. The tap is configured with a modified bottoming chamfer of 2 to 2.5 threads, making it well suited for threading close to the bottom of blind holes. The overall length is 3.937 inches (100 mm), with a thread length of 0.626 inches (16 mm) and a maximum tapping depth of 1.575 inches (40 mm). It is sized for 3\/8-16 UNC threads at a 2B class of fit with an H7 thread limit. Installed by machinists and maintenance technicians working in production or toolroom environments.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for blind hole threading applications across a wide range of materials including aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloy, and titanium. The coolant-through design supports high-speed tapping operations where through-spindle coolant or oil is available, helping to manage heat and extend tool life in difficult materials. It is appropriate for CNC machining centers, tapping machines, and rigid-tapping setups where consistent thread quality is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming (chipless) operation produces stronger threads and eliminates chip evacuation concerns in blind holes\u003c\/li\u003e\n  \u003cli\u003eCobalt HSS construction provides heat and wear resistance in tough alloys and stainless steel\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves surface hardness and reduces friction during the forming process\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2 to 2.5P) allows threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed tapping with through-spindle coolant or oil\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, 3\/8-16 UNC, H7 thread limit for consistent 2B class of fit results\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in aluminum, cast aluminum, hardened steel, carbon steel, alloy steel, die steel, stainless steel, high-nickel alloy, and titanium (material application codes P, M, K, N, H).

Use a rigid tapping setup or a synchronized tapping head to prevent thread distortion or tap breakage. Apply appropriate tapping fluid or ensure through-spindle coolant is active before engaging the tap. Always verify spindle RPM and feed rate are matched to the material and tap size per the manufacturer's recommended parameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2 to 2.5P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.937 inches (100 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.626 inches (16 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.575 inches (40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.286 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\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16050 (EXOPRO XPF-OIL)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.103 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: 1605038167\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51754804183346,"sku":"1605038167","price":188.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/279692742061a87d06b545b80fafa0bf_c620977c-1729-4282-b95d-b4730ec1feb3.jpg?v=1788948768","url":"https:\/\/voomisupply.com\/products\/osg-1605038167-thread-forming-tap-3-8-16-unc-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
