Part of the HY-PRO NRT series, it cuts 10-24 UNC right-hand threads to a class 3B fit with an H4 thread limit. At 2.375 inches overall length, the tap features a bottoming chamfer of 1 to 1.5 threads, allowing threads to be formed close to the bottom of a blind hole. The bright finish cobalt construction provides heat resistance and durability across a wide range of workpiece materials. This tap is suited for machine shop, maintenance, and production threading operations performed by machinists and tool-and-die technicians.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for blind hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. The bottoming chamfer makes it the correct choice when full threads must extend close to the base of a blind hole. It is used in production machining, MRO operations, and precision fabrication environments where 10-24 UNC fastener holes are required. The thread forming design displaces rather than cuts material, which reduces chip formation and is particularly effective in ductile metals such as aluminum and mild steel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e10-24 UNC thread form, right-hand direction, class 3B fit\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer of 1 to 1.5 threads for threading close to hole base\u003c\/li\u003e\n  \u003cli\u003eCobalt construction for increased heat resistance in tough alloys and stainless steel\u003c\/li\u003e\n  \u003cli\u003eH4 thread limit for consistent fit in standard UNC tolerance applications\u003c\/li\u003e\n  \u003cli\u003eThread forming design eliminates chips, reducing tap breakage risk in ductile materials\u003c\/li\u003e\n  \u003cli\u003eBright finish with no coolant-through requirement for straightforward setup\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 10-24 UNC class 3B threads.

The pilot hole diameter must be correctly sized per UNC thread forming tap recommendations before use. Cutting fluid or tapping compound appropriate for the workpiece material should be applied during operation. Ensure the workpiece is securely fixtured and the spindle is properly aligned to avoid tap breakage.\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 1 to 1.5P\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: 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.492 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.866 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\u003eSquare Length\u003c\/strong\u003e: 0.250 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\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 (14001)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 1400117900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51749436555570,"sku":"1400117900","price":30.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e0a7535aeb52c331c9ab34d6077839_34323f58-352d-4e1d-978c-11baa5efc042.jpg?v=1788906082","url":"https:\/\/voomisupply.com\/products\/osg-1400117900-thread-forming-tap-10-24-unc-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
