It carries a 10-24 UNC thread profile with a bottoming chamfer of 1 to 1.5 threads, allowing it to tap close to the bottom of a blind hole. The tap is manufactured from cobalt high-speed steel and finished with a TiN coating to extend tool life under demanding cutting conditions. At 2.375 inches overall length with a shank diameter of 0.194 inches, it is sized for standard tap holders and machine tapping setups. Machinists, tool and die makers, and production shop technicians are the primary users of this tap.\u003c\/p\u003e\u003cp\u003eThis tap is suited for blind hole threading operations in a wide range of metallic workpieces. The HY-PRO NRT series is rated for use in alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. The bottoming chamfer makes it appropriate as a finishing tap after a plug or spiral point tap has started the thread. It is commonly used in production machining, maintenance and repair operations, and toolroom work where a 10-24 UNC internal thread with a Class 3B fit and H4 thread limit is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottoming chamfer of 1 to 1.5 threads for threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eCobalt construction provides increased heat and wear resistance compared to standard HSS\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends tool life across multiple materials\u003c\/li\u003e\n\u003cli\u003eH4 thread limit delivers Class 3B fit for close-tolerance threaded assemblies\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, compatible with standard tapping attachments and CNC machines\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design; external flood or mist coolant is appropriate\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum workpieces requiring a 10-24 UNC Class 3B internal thread.

Ensure the workpiece is securely fixtured and the spindle is properly aligned before tapping to avoid tap breakage in blind holes. Use a compatible cutting fluid or tapping fluid suitable for the workpiece material; do not run dry. Always power down or de-energize the machine before changing tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 1 to 1.5 threads\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 24\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\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\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN\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\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\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: 0.022 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1400117905\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730055135538,"sku":"1400117905","price":38.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0922f25ef67b34bfc7e47386476142b.jpg?v=1788710897","url":"https:\/\/voomisupply.com\/products\/osg-1400117905-thread-forming-tap-10-24-unc-bottoming-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
