Made from cobalt high-speed steel with a bright finish, this tap displaces material to produce strong, work-hardened threads in blind holes. It carries a H5 thread limit and a Class 2B fit, making it suitable for precision threaded fastener applications where consistent thread geometry is required. At 2.375 inches overall length with a 0.194-inch shank diameter, it fits standard tap holders used in manual and machine tapping setups. Right-hand thread direction, 32 threads per inch, and a 1 to 1.5 chamfered thread lead complete the specification profile.\u003c\/p\u003e\u003cp\u003eThis tap is intended for blind hole threading in a wide range of workpiece materials including alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. The forming action rather than cutting action makes it particularly well suited for ductile and semi-ductile metals where chip-free threading is an advantage. Machinists, tool-and-die makers, and maintenance technicians will find this tap applicable in production, repair, and prototype work across aerospace, automotive, and general industrial environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design produces chip-free blind hole threads in ductile metals\u003c\/li\u003e\n\u003cli\u003eCobalt construction provides elevated heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer with 1 to 1.5 chamfered threads allows threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eH5 thread limit and Class 2B fit for controlled, consistent thread tolerance\u003c\/li\u003e\n\u003cli\u003eBright finish suitable for general-purpose use across a broad material range\u003c\/li\u003e\n\u003cli\u003eRight-hand, 10-32 UNF thread form at 32 threads per inch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole thread forming applications in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Ensure the workpiece is securely fixtured and apply appropriate tapping fluid or cutting oil for the material being tapped. Use a calibrated torque-limiting tap driver or CNC rigid tapping cycle where available to prevent tap breakage. Inspect the tap for chipping or deformation before each use, particularly when working in hardened steel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-32 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Style\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\u003eClass of Fit\u003c\/strong\u003e: 2B\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\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: 0.25 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: 0.021 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: 1400120100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51734867509554,"sku":"1400120100","price":30.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e0a7535aeb52c331c9ab34d6077839_1b40a775-2caf-4c39-b0f0-d6df42bc506c.jpg?v=1788767462","url":"https:\/\/voomisupply.com\/products\/osg-1400120100-thread-forming-tap-10-32-unf-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
