Part of the HY-PRO NRT series, it produces a 10-32 UNF thread with a bottoming chamfer of 1 to 1.5 threads, allowing threads to be formed close to the bottom of a blind hole. The cobalt construction provides heat and wear resistance, and the steam oxide coating reduces friction and improves lubricity during the forming process. Overall length is 2.375 inches with a shank diameter of 0.194 inches. Installed by machinists and tool-and-die professionals in precision threading operations.\u003c\/p\u003e\u003cp\u003eThis tap is suited for blind hole threading applications across a wide range of metals. Applicable material groups include alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel, covering both P and N material application codes. The bottoming chamfer makes it particularly well suited for through-tapping to the base of shallow blind holes where full thread engagement near the bottom is required. It is commonly used in production machining, maintenance and repair operations, and tooling fabrication environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design eliminates chips, reducing blind hole clogging during tapping\u003c\/li\u003e\n\u003cli\u003eCobalt construction resists heat buildup in demanding materials including hardened and stainless steel\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating lowers friction and extends tool life in ferrous and non-ferrous applications\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer of 1 to 1.5 threads enables threading close to the base of a blind hole\u003c\/li\u003e\n\u003cli\u003eH6 thread limit provides tight tolerance control for consistent thread fit\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction for standard machine and hand 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 a 10-32 UNF right-hand internal thread.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread forming taps require proper hole preparation with a recommended forming tap drill size, which differs from a cutting tap drill chart  -  consult the OSG HY-PRO NRT series drill size guidelines before drilling. Use a suitable tapping fluid or cutting oil appropriate for the workpiece material, particularly when tapping stainless or hardened steel. Secure the workpiece fully before tapping and ensure the tap is driven perpendicular to the work surface to avoid thread distortion. No coolant-through capability is present on this tap, so external lubrication at the tap entry is required.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H6\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: Steam Oxide\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\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\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.025 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: 1400157201\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51740321481010,"sku":"1400157201","price":30.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b00eed4db0523def1206193b257ff4f.jpg?v=1788824286","url":"https:\/\/voomisupply.com\/products\/osg-1400157201-thread-forming-tap-10-32-unf-bottoming-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
