Built from cobalt high-speed steel and finished with a titanium nitride (TiN) coating, it handles demanding threading applications in alloy steel, carbon steel, stainless steel, hardened steel, die steel, and aluminum. The modified bottoming chamfer — with 2 to 2.5 chamfered threads — allows the tap to thread close to the bottom of a blind hole. Thread limit is H5, providing tight tolerance control for 10-24 UNC threads. Licensed machinists and tool-and-die tradespeople are the primary users of this tap.\u003c\/p\u003e\u003cp\u003eThis tap is suited for blind hole threading operations on the shop floor or in the field where chip evacuation is a concern. Because thread forming displaces material rather than cutting it, the process produces stronger thread forms and eliminates the need to clear chips from the bore. It is appropriate for both production runs and precision one-off threading tasks in materials coded P and N per the HY-PRO NRT classification system.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design cold-forms threads without producing chips, ideal for blind hole applications\u003c\/li\u003e\n\u003cli\u003eCobalt high-speed steel construction provides heat and wear resistance in tough materials\u003c\/li\u003e\n\u003cli\u003eTiN coating extends tool life and reduces friction during forming\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer (2 to 2.5 threads) allows threading close to the bottom of a blind hole\u003c\/li\u003e\n\u003cli\u003eH5 thread limit for consistent, tight-tolerance 10-24 UNC thread production\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, compatible with standard tapping equipment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for threading alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces with 10-24 UNC blind hole requirements.

Apply appropriate tapping fluid for the workpiece material before forming. Secure the workpiece and use a calibrated torque driver or CNC tapping cycle to avoid tap breakage, particularly near the bottom of the blind hole. Always follow shop safety protocols and machine-specific operating procedures when tapping.\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\u003eThreads per Inch\u003c\/strong\u003e: 24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\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\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\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\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\u003eWeight\u003c\/strong\u003e: 0.021 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HY-PRO NRT (14001)\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: 1400118405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748432412978,"sku":"1400118405","price":38.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2eeb30fe755b44f64644ca3dbcbd33a9.jpg?v=1788893747","url":"https:\/\/voomisupply.com\/products\/osg-1400118405-thread-forming-tap-10-24-unc-cobalt-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
