Unlike cutting taps, thread forming taps displace material rather than cut it, producing stronger threads with no chips — a key advantage in blind hole applications. Manufactured from high-speed steel and coated with titanium nitride (TiN) for improved wear resistance and tool life, this tap carries an H4 thread limit for close-tolerance threading work. The overall length is 2.375 inches with a thread length of 0.875 inches and a shank diameter of 0.194 inches. Machinists and toolroom technicians install this tap in drill presses, CNC machining centers, and tapping fixtures.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for blind hole threading in ductile materials where chipless thread forming is preferred over conventional cutting. The bottoming chamfer — with 1 to 2 chamfered threads — allows the tap to reach the bottom of a blind hole and produce full threads as close to the hole base as possible. Typical applications include threaded fastener holes in aluminum, mild steel, and other machinable metals in production machining, maintenance, and toolroom environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer with 1-2 chamfered threads for threading near the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eThread forming design displaces material rather than cutting, eliminating chips and producing stronger threads\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides toughness and heat resistance during tapping operations\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride coating increases surface hardness and extends tool life in high-cycle applications\u003c\/li\u003e\n  \u003cli\u003eH4 thread limit supports close-tolerance fit requirements in 10-24 UNC threaded holes\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; no coolant-through feature — suitable for standard tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use thread forming tap for 10-24 UNC blind hole threading applications in compatible drill presses, CNC machining centers, and hand tapping fixtures that accept a 0.194-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread forming taps require a larger pilot hole diameter than cutting taps — consult a thread forming drill chart for the correct forming drill size for 10-24 UNC before drilling. Secure the workpiece fully and ensure the tapping fixture or machine spindle is properly aligned to avoid tap breakage. Use a suitable tapping fluid or cutting oil appropriate for the workpiece material. Inspect the tap for wear or damage before each use; replace when thread quality degrades.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\u003eThread Limit\u003c\/strong\u003e: H4\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 (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.194 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.152 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\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: K010349AS25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51754459398450,"sku":"K010349AS25","price":46.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6dbe03cf2351560eed23ae5ca9d9386.jpg?v=1788945623","url":"https:\/\/voomisupply.com\/products\/hertel-k010349as25-thread-forming-tap-10-24-unc-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
