Unlike cutting taps, thread forming taps displace material rather than cut it, producing stronger threads with no chip generation. This tap is manufactured from high-speed steel with a TiCN (titanium carbonitride) coating, which improves surface hardness and wear resistance for extended tool life in production environments. At 1.75 inches overall length with a 0.4375-inch thread length, it is sized for small-diameter fastener holes commonly found in precision assemblies. A bottoming chamfer of 1 to 2 threads allows threading close to the bottom of blind holes. Licensed machinists, tool-and-die makers, and maintenance technicians install this tap by hand or with tapping machines.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for forming 2-56 UNC right-hand internal threads in blind holes where chip evacuation is a concern or where maximum thread strength is required. The H2 thread limit designation indicates a close tolerance fit, making it appropriate for precision components in electronics, instrumentation, and light mechanical assemblies. It is well-matched to ductile materials such as aluminum, brass, and mild steel where cold-forming is effective. The bottoming geometry makes it the correct choice when threads must extend as close as possible to the floor of a blind hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design eliminates chips, reducing risk of chip packing in blind holes\u003c\/li\u003e\n  \u003cli\u003eTiCN coating increases surface hardness and extends tool life over uncoated HSS taps\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer (1-2 threads) allows threading to within one or two pitches of hole bottom\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit for close-tolerance 2-56 UNC fits\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction for standard tapping operations\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction suitable for use with hand tapping or low-speed machine tapping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for forming 2-56 UNC right-hand internal threads in blind holes in ductile workpiece materials. Verify material suitability for cold-forming before use, as thread forming taps require adequate material ductility.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by a machinist or toolmaker using a tap wrench, tapping head, or CNC tapping cycle. Secure the workpiece before tapping and ensure the pilot hole diameter is correct for the thread forming process, as forming taps require a larger pilot hole than cutting taps for the same thread size. Apply appropriate tapping fluid for the workpiece material to reduce galling and extend tap life. Never reverse a forming tap under load without adequate lubrication, and do not exceed the tap's rated speed range for the material being formed.\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 1-2P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\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: 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: No\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: 0.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1410 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.1100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K010306AS85\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748655628594,"sku":"K010306AS85","price":72.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/db307a10bde9fac4804cb568ea6564e6.jpg?v=1788896261","url":"https:\/\/voomisupply.com\/products\/hertel-k010306as85-thread-forming-tap-2-56-unc-bottoming-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
