Part of the HY-PRO NRT series, this tap uses a modified bottoming chamfer with 2 to 2.5 chamfered threads, allowing it to thread close to the bottom of a blind hole. Manufactured from cobalt high-speed steel with a steam oxide coating, the 1400142701 is built for durability in demanding production environments. At 3.375 inches overall length with a 0.921-inch thread length and a shank diameter of 0.367 inches, it fits standard tapping chucks and holders used in CNC and manual tapping setups. Right-hand thread direction and H4 thread limit ensure consistent, on-tolerance threads across production runs.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum workpieces. The modified bottoming chamfer makes it the correct choice when full thread depth close to the floor of a blind hole is required. It is commonly used in machining, toolroom, and production environments where 1\/2-13 UNC fastener threads are tapped directly into component blanks or assemblies. The cobalt substrate offers added heat resistance compared to standard M2 HSS, making it appropriate for harder or more abrasive materials at normal tapping speeds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eModified bottoming chamfer with 2 to 2.5 chamfered threads for threading near the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eCobalt high-speed steel construction for improved heat and wear resistance in tough materials\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating reduces friction and helps retain cutting lubricant during tapping\u003c\/li\u003e\n\u003cli\u003eH4 thread limit provides consistent thread tolerance for 1\/2-13 UNC applications\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction; no coolant-through requirement simplifies setup\u003c\/li\u003e\n\u003cli\u003eCompatible with alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole 1\/2-13 UNC thread forming in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Ensure the workpiece is securely fixtured and the tap is properly aligned with the drilled hole before engaging to prevent tap breakage or cross-threading. Apply an appropriate tapping fluid or cutting oil for the workpiece material before and during tapping. Follow standard shop safety procedures, including machine lockout when changing or inspecting taps.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\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\u003eThreads per Inch\u003c\/strong\u003e: 13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: 0.921 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\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\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 (14001)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.175 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: 1400142701\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752560951602,"sku":"1400142701","price":74.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e0a7535aeb52c331c9ab34d6077839_ce877606-506e-44f4-8024-310544c5766f.jpg?v=1788929105","url":"https:\/\/voomisupply.com\/products\/osg-1400142701-thread-forming-tap-1-2-13-unc-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
