Part of the HY-PRO NRT series, it is manufactured from cobalt high-speed steel with a bright finish and carries an H4 thread limit for precise tolerance control. The modified bottoming chamfer features 2 to 2.5 chamfered threads, allowing the tap to reach close to the bottom of a blind hole. Overall length is 3.156 inches with a shank diameter of 0.323 inches. This tap is suited for production threading operations performed by machinists and tool and die professionals.\u003c\/p\u003e\n\u003cp\u003eThe 1400139100 is built for blind hole threading across a range of ferrous and non-ferrous workpiece materials. Its cobalt construction makes it well-suited for demanding cuts in alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. The HY-PRO NRT design uses a thread forming rather than thread cutting action, displacing material rather than producing chips, which is advantageous in blind hole setups where chip evacuation is a concern.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/16-14 UNC thread size with right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer with 2 to 2.5 chamfered threads for near-bottom reach in blind holes\u003c\/li\u003e\n  \u003cli\u003eCobalt high-speed steel construction for durability in alloy steel, stainless steel, and hardened steel\u003c\/li\u003e\n  \u003cli\u003eH4 thread limit for consistent tolerance performance\u003c\/li\u003e\n  \u003cli\u003eBright finish with no coolant-through requirement, suitable for standard tapping setups\u003c\/li\u003e\n  \u003cli\u003eThread forming action eliminates chip production in blind hole applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Ensure the workpiece is securely fixtured and the pilot hole diameter is correct for thread forming, as forming taps require a larger pilot hole than cutting taps for the same thread size. Apply appropriate tapping fluid or cutting oil rated for the workpiece material before and during the tapping operation. Power down and de-energize any machine before changing or inspecting the tap.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-14\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\u003eThreads per Inch\u003c\/strong\u003e: 14\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: H4\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\/Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.156 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.858 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.713 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.323 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.242 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.406 inches\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: 0.155 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: 1400139100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51749326455090,"sku":"1400139100","price":64.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/54007605c86a35ccbe500237473ad7c4.jpg?v=1788904570","url":"https:\/\/voomisupply.com\/products\/osg-1400139100-thread-forming-tap-7-16-14-unc-cobalt-h4","provider":"Voomi Supply","version":"1.0","type":"link"}
