It produces a 10-24 UNC right-hand thread using a modified bottoming chamfer with 2 to 2.5 chamfered threads, making it well suited for blind hole applications where thread depth control is critical. Constructed from cobalt high-speed steel with a steam oxide coating, this tap offers improved lubricity and resistance to wear and galling. 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 tool-and-die technicians install this tap in CNC machining centers, drill presses, and tapping machines.\u003c\/p\u003e\u003cp\u003eThis tap is intended for blind hole threading in a range of metallic materials including alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. The modified bottoming chamfer allows threading close to the bottom of a blind hole, which is a common requirement in precision machined components, fastener bosses, and structural assemblies across industrial, aerospace, and automotive applications. It carries a Thread Limit of H5, which defines the pitch diameter tolerance and ensures consistent fit with standard UNC fasteners across production runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design eliminates chips, reducing tap breakage risk in blind hole operations\u003c\/li\u003e\n\u003cli\u003eCobalt construction provides elevated heat and wear resistance compared to standard HSS\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating improves surface lubricity and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer with 2 to 2.5 chamfered threads for close-to-bottom threading in blind holes\u003c\/li\u003e\n\u003cli\u003eH5 thread limit ensures controlled pitch diameter for consistent UNC thread fitment\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction; no coolant-through requirement simplifies tooling setup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Ensure the workpiece is securely fixtured and the tap is driven with a synchronized tapping head or CNC rigid tapping cycle to prevent thread distortion. Apply an appropriate tapping fluid or cutting oil for the workpiece material before starting. Power down and de-energize all machine drives before changing or inspecting 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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\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\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\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\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: 0.015 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: 1400118401\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752182284594,"sku":"1400118401","price":30.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9fdf52cebe35cfe46f490fa22085f217.jpg?v=1788926402","url":"https:\/\/voomisupply.com\/products\/osg-1400118401-thread-forming-tap-10-24-unc-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
