It produces a 1\/2-20 UNF right-hand thread using a modified bottoming chamfer with 2 to 2.5 chamfered threads, allowing it to thread close to the bottom of a blind hole. Made from cobalt high-speed steel with a bright finish, this tap carries a Thread Limit of H6 and measures 3.375 inches in overall length. Licensed machinists and tool and die professionals use this tap in production and maintenance threading operations where chip-free thread forming is preferred.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for blind hole threading in a range of metallic workpiece materials, including alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. The modified bottoming chamfer makes it a practical choice when thread depth must be maximized in a stopped bore. With a tapping depth of 1.933 inches and a thread length of 0.9213 inches, it delivers consistent thread form in both manual and machine tapping setups across production and job shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forms 1\/2-20 UNF right-hand threads via cold-forming, eliminating chips in the bore\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer with 2 to 2.5 chamfered threads for threading close to blind hole bottoms\u003c\/li\u003e\n  \u003cli\u003eCobalt high-speed steel construction for heat and wear resistance in tough alloys and hardened steel\u003c\/li\u003e\n  \u003cli\u003eH6 thread limit for close-tolerance thread production\u003c\/li\u003e\n  \u003cli\u003eBright finish suitable for use with cutting fluids and standard tapping lubricants\u003c\/li\u003e\n  \u003cli\u003eCompatible with alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind hole threading applications in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Always apply an appropriate tapping fluid or cutting oil matched to the workpiece material before starting. Ensure the tap is properly aligned with the drilled pilot hole to avoid tap breakage or thread distortion. Power down all machine tools and secure the workpiece before changing or setting taps.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20\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: 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: H6\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: 3.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.9213 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.933 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.275 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.4375 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: 0.18 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 1400144700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752616132914,"sku":"1400144700","price":72.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e0a7535aeb52c331c9ab34d6077839_2003f6a9-395e-4db2-968b-75a12a3d8617.jpg?v=1788929384","url":"https:\/\/voomisupply.com\/products\/osg-1400144700-thread-forming-tap-1-2-20-unf-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
