Part of the HY-PRO NRT series, this 3\/4-10 UNC 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 bright coating, it measures 4.25 inches overall length with a thread limit of H6. The right-hand, single-point thread forming action displaces material rather than cutting chips, reducing the risk of chip clogging in blind holes. Licensed machinists, tool and die makers, and maintenance technicians working on structural assemblies typically install this tap.\u003c\/p\u003e\u003cp\u003eThis tap is suited for blind hole threading operations in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. The modified bottoming chamfer makes it a practical choice when thread depth close to the bottom of a blind hole is required. It is commonly used in manufacturing, maintenance, and repair environments where 3\/4-10 UNC internal threads are specified. The HY-PRO NRT series is engineered for thread forming applications where chip-free tapping is preferred over conventional cut tapping.\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 close to blind hole bottoms\u003c\/li\u003e\n\u003cli\u003eCobalt high-speed steel construction for improved heat and wear resistance in tough materials\u003c\/li\u003e\n\u003cli\u003eBright coating finish suitable for general-purpose thread forming across a wide material range\u003c\/li\u003e\n\u003cli\u003eH6 thread limit for controlled fit in standard UNC tolerance applications\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, 3\/4-10 UNC specification\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design — compatible with external flood or mist coolant delivery\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole thread forming in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel.

Power down all equipment and secure the workpiece before beginning any tapping operation. Use an appropriate tapping fluid or cutting oil rated for the workpiece material — this is especially important when working with stainless steel or hardened steel. Follow shop standards and applicable safety codes when operating machine tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-10 UNC\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: 10\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: H6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.2008 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 2.433 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.59 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.442 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.6875 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\/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\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Materials\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: 0.365 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: 1400153500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732513849650,"sku":"1400153500","price":114.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e0a7535aeb52c331c9ab34d6077839_81c8bec1-098c-4d9a-8e76-69e3cd0dd3f0.jpg?v=1788743841","url":"https:\/\/voomisupply.com\/products\/osg-1400153500-thread-forming-tap-3-4-10-unc-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
