This tap uses a modified bottoming chamfer with 2 to 2.5 chamfered threads, making it suited for threading close to the bottom of blind holes. It operates with a right-hand thread direction and carries an H6 thread limit with a Class 2B fit. Overall length is 2.375 inches, with a thread length of 0.492 inches and a tapping depth of 0.866 inches. Licensed machinists and toolroom technicians install this tap in production and maintenance applications where chip-free forming is required.\u003c\/p\u003e\u003cp\u003eThis tap is intended for blind hole threading across a range of metals. Rated material applications include alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. The HY-PRO NRT series designation indicates OSG's cold-forming geometry, which displaces material rather than cutting it, producing stronger formed threads with no chips to clear. It is well-suited for CNC tapping centers, drill presses with tapping attachments, and manual tap handles where controlled torque is maintained.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eModified bottoming chamfer with 2 to 2.5 chamfered threads for threading near the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eCobalt construction provides heat and wear resistance for demanding materials including hardened steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends tool life across high-cycle applications\u003c\/li\u003e\n\u003cli\u003eThread forming (chipless) design eliminates chip evacuation concerns in blind hole setups\u003c\/li\u003e\n\u003cli\u003eH6 thread limit and Class 2B fit for standard tolerance threading\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction; compatible with standard tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces requiring 10-24 UNC threads at a Class 2B fit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread forming taps require a properly sized forming tap drill — use the correct recommended tap drill diameter for 10-24 UNC cold-form tapping, as it differs from standard cut tap drill charts. Power down all equipment before installing or removing the tap from the holder. Apply appropriate tapping fluid or cutting oil for the workpiece material; adequate lubrication is critical for thread forming operations. Ensure the tapping attachment or spindle provides sufficient torque control to avoid tap breakage in harder materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-24 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2 to 2.5P\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: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H6\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: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\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\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Die Steel, Hardened Steel, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 0.021 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: 1400118505\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731678921010,"sku":"1400118505","price":38.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e0a7535aeb52c331c9ab34d6077839_a1a2fe66-1d00-4b50-8853-d8b10e77b9be.jpg?v=1788733815","url":"https:\/\/voomisupply.com\/products\/osg-1400118505-thread-forming-tap-10-24-unc-cobalt-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
