It produces a 5-44 UNF right-hand thread using a modified bottoming chamfer with 2 to 2.5 chamfered threads, making it suitable for threading close to the bottom of blind holes. Built from cobalt high-speed steel with a bright finish, this tap carries a H4 thread limit and is intended for use by machinists and tooling technicians in precision metalworking environments. Overall length is 1.938 inches with a tapping depth of 0.626 inches.\u003c\/p\u003e\n\u003cp\u003eThis tap is rated for blind hole threading applications across a range of workpiece materials including alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. The modified bottoming chamfer allows threading deeper into blind holes compared to standard plug chamfer taps, making it a practical choice for close-tolerance fastener holes in machined components, fixtures, and tooling assemblies. It is suited to CNC tapping centers, drill presses, and manual tapping operations where 5-44 UNF thread production is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming (chipless) design eliminates chip evacuation concerns in blind holes\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2 to 2.5 threads) for threading near the bottom of a blind hole\u003c\/li\u003e\n  \u003cli\u003eCobalt high-speed steel construction for improved heat and wear resistance in tough materials\u003c\/li\u003e\n  \u003cli\u003eH4 thread limit for controlled fit in precision threaded assemblies\u003c\/li\u003e\n  \u003cli\u003eRight-hand, 5-44 UNF thread form at 44 threads per inch\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement; compatible with flood or manual lubrication\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\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 internal thread.

Ensure the workpiece is securely fixtured and that the tap is properly aligned axially before engagement to prevent tap breakage in small-diameter threads. Use a cutting or forming fluid appropriate for the workpiece material to reduce heat and extend tool life. Because this is a forming tap, the pilot hole diameter must be sized to the thread-forming specification rather than a standard drill chart for cut taps.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eThreads per Inch\u003c\/strong\u003e: 44\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: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2 to 2.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H4\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\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 1400109000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51746414362930,"sku":"1400109000","price":35.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e0a7535aeb52c331c9ab34d6077839_9e9862b2-4863-40f1-b39a-5f7de493bc6c.jpg?v=1788869796","url":"https:\/\/voomisupply.com\/products\/osg-1400109000-thread-forming-tap-5-44-unf-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
