Unlike cutting taps, this tool displaces material to produce threads, resulting in stronger thread forms with no chips to evacuate. It is manufactured from cobalt high-speed steel for elevated heat and wear resistance, and carries a TiCN (titanium carbonitride) coating to reduce friction and extend tool life. The tap is configured with a modified bottoming chamfer of 2 to 2.5 threads, making it well-suited for blind hole applications where threads must extend close to the bottom of the bore. Overall length is 3.937 inches (100 mm) and thread length is 0.626 inches (16 mm).\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for production and precision machining environments where thread integrity and tool longevity are priorities. It is suited for use in blind hole threading operations across a wide range of workpiece materials, including aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloys, and titanium. The coolant-through design supports high-speed tapping with internal coolant delivery for effective lubrication and heat management at the cutting zone. It is used by machinists, tool-and-die makers, and CNC operators in job shops, aerospace, and industrial manufacturing settings. The 3\/8-24 UNF thread specification and 2B class of fit make it appropriate for fine-thread fastener assemblies requiring controlled tolerance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming (chipless) design produces stronger threads and eliminates chip evacuation concerns in blind holes\u003c\/li\u003e\n  \u003cli\u003eCobalt HSS construction provides increased red hardness for tapping difficult alloys and hardened steels\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and improves wear resistance across extended production runs\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2 to 2.5 threads) allows threading close to the bottom of blind bores\u003c\/li\u003e\n  \u003cli\u003eCoolant-through capability supports internal flood or mist lubrication for high-speed operations\u003c\/li\u003e\n  \u003cli\u003eH7 thread limit provides consistent 2B class of fit tolerance across production runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind hole thread forming in aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloys, and titanium.

Before use, verify that the pilot hole diameter is correctly sized for thread forming to the 3\/8-24 UNF specification, as forming taps require a larger pilot hole than equivalent cutting taps. Use recommended tapping fluid or activate through-spindle coolant before engaging the tap. Inspect the tap for wear or coating damage before each production run to avoid thread-quality defects.\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 UNF\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\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\u003eApplication\u003c\/strong\u003e: Blind 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\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Hardened Steel, Carbon Steel, Alloy Steel, Die Steel, Stainless Steel, High-Nickel Alloy, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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\u003eWeight\u003c\/strong\u003e: 0.105 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16050 (EXOPRO XPF-OIL)\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: 1605038247\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728218718514,"sku":"1605038247","price":171.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/279692742061a87d06b545b80fafa0bf_1bd16716-32e7-4e70-b3bd-4fdb56cca977.jpg?v=1788689747","url":"https:\/\/voomisupply.com\/products\/osg-1605038247-thread-forming-tap-3-8-24-unf-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
