Sized for 2-56 UNC thread profiles, this tap uses a modified bottoming chamfer with 2 to 2.5 chamfered threads, allowing it to reach near the bottom of blind holes. The tool is manufactured from cobalt and finished with a steam oxide coating to reduce friction and improve wear resistance. Overall length is 1.75 inches with a thread length of 0.437 inches. Licensed trade professionals and machining shops use this tap for precision threading in production and maintenance applications.\u003c\/p\u003e\n\u003cp\u003eThis tap is engineered for blind hole threading across a wide range of metallic workpiece materials, including alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. The right-hand thread direction and H5 thread limit make it suited to applications where close tolerance fits are required. Typical use cases include threading small-diameter fastener holes in machined components, fixtures, and assemblies where chip-free forming is preferred over conventional cutting taps.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design produces no chips, reducing clearing requirements in blind holes\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer with 2 to 2.5 chamfered threads for near-bottom reach\u003c\/li\u003e\n  \u003cli\u003eCobalt construction provides heat and wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating reduces friction and extends tool life\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit for close-tolerance 2-56 UNC internal threads\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, compatible with standard tapping chucks and CNC spindles\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 2-56 UNC right-hand internal threads.

Always apply appropriate tapping fluid or cutting oil matched to the workpiece material before use. Power down all equipment and secure the workpiece fully before engaging the tap. Use a calibrated torque-limiting tap holder where possible to avoid tool breakage in small-diameter applications at this size range.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 56\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Style\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 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\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.437 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.476 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\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\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: 0.005 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: 1400102801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727086911794,"sku":"1400102801","price":38.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e0a7535aeb52c331c9ab34d6077839.jpg?v=1788673088","url":"https:\/\/voomisupply.com\/products\/osg-1400102801-thread-forming-tap-2-56-unc-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
