Manufactured from high-speed steel with a titanium nitride coating, it delivers increased surface hardness and extended tool life compared to uncoated alternatives. The bottoming chamfer — 1 to 2 threads — allows threading close to the bottom of blind holes where clearance is limited. With an overall length of 1.9375 inches and a thread length of 0.625 inches, it is a compact tooling solution suited for precision threading in small fastener applications. Class of fit is 2B and 3B with an H3 thread limit, and thread direction is right hand.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machining, tool and die, and maintenance repair operations where 5-40 UNC threads are required in blind-hole configurations. It is well suited for work in ferrous and non-ferrous metals where thread forming — rather than cutting — displaces material to produce stronger, smoother threads without generating chips. Machinists, tool room technicians, and maintenance professionals working with small-diameter fastener threads will find this tap appropriate for production and repair work in close-tolerance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer (1-2 threads) for threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across a range of work materials\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride coating increases surface hardness and reduces wear\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit for consistent 2B and 3B class of fit results\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, 5-40 UNC thread standard\u003c\/li\u003e\n  \u003cli\u003eChipless thread forming process produces stronger threads and eliminates chip clearance concerns in blind holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for applications requiring 5-40 UNC thread forming in blind holes at 2B or 3B class of fit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread forming taps are installed and driven by machinists or tool room technicians using a standard tap wrench, tapping head, or CNC machine with appropriate speed and feed settings for the work material. Before use, ensure the pilot hole diameter is correct for thread forming — forming taps require a slightly larger pilot hole than cutting taps. Secure the workpiece firmly and apply appropriate tapping fluid to extend tool life and maintain thread quality. Never reverse a thread forming tap under power without confirming the machine is set for proper reversal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B and 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Style\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 Direction\u003c\/strong\u003e: Right Hand\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: Titanium Nitride\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.9375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.625 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: 0.11 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: K010323AS25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732803289394,"sku":"K010323AS25","price":42.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8d57e23d4cd2de16b6df8db85f63c771.jpg?v=1788746990","url":"https:\/\/voomisupply.com\/products\/hertel-k010323as25-thread-forming-tap-5-40-unc-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
