It carries a 5-44 UNF thread specification with a modified bottoming chamfer of 2 to 2.5 chamfered threads, making it well-suited for threading close to the bottom of blind holes. Manufactured from cobalt high-speed steel with a bright finish, the tap delivers added heat and wear resistance in demanding drilling environments. The H5 thread limit and Class 2B fit ensure consistent, on-spec thread geometry. Licensed machinists, tool-and-die technicians, and precision machine shops are the typical end users.\u003c\/p\u003e\u003cp\u003eThis tap is intended for blind hole threading applications across a wide range of materials. Its material application includes alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel, making it a versatile choice for production and maintenance shops working with mixed workpiece materials. The right-hand thread direction and standard 5-44 UNF configuration make it a direct-fit option for precision fastener applications in aerospace, automotive, and general manufacturing contexts where fine-thread engagement in small-diameter holes is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design eliminates chips, reducing clogging risk in blind hole applications\u003c\/li\u003e\n\u003cli\u003eCobalt construction provides increased heat resistance compared to standard HSS taps\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer (2 to 2.5 threads) allows threading closer to hole bottom\u003c\/li\u003e\n\u003cli\u003eH5 thread limit with Class 2B fit for consistent, controlled thread tolerance\u003c\/li\u003e\n\u003cli\u003eBright finish suitable for general-purpose use across multiple ferrous and non-ferrous materials\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\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces requiring a 5-44 UNF Class 2B internal thread.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed in a rigid tapping holder or CNC tapping head by a qualified machinist. Ensure the workpiece is securely fixtured and the pilot hole diameter is correctly sized for thread forming before operation. Coolant through is not available on this tap, so appropriate surface-applied cutting fluid should be used based on workpiece material. Follow shop-standard speeds and feeds for cobalt thread forming taps on the target material to avoid tap breakage or thread distortion.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-44\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\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\u003eThreads per Inch\u003c\/strong\u003e: 44\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: H5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\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: 1.938 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.299 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.626 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.110 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 1400109100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727092187442,"sku":"1400109100","price":32.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e0a7535aeb52c331c9ab34d6077839_c278a689-d32e-421f-a24e-20b5fb8e3bfe.jpg?v=1788673182","url":"https:\/\/voomisupply.com\/products\/osg-1400109100-thread-forming-tap-5-44-unf-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
