Made from cobalt high-speed steel and finished with a TiCN coating, it handles the torsional and thermal demands of threading alloy steel, stainless steel, hardened steel, carbon steel, die steel, and aluminum. The bottoming chamfer (1 to 1.5 chamfered threads) allows threading to near the bottom of blind holes. Thread limit is H6, which keeps the formed thread within a tight tolerance class suited to precision fastener applications. Installation is performed by licensed machinists or tool-and-die professionals using a tapping head or CNC machine.\u003c\/p\u003e\n\u003cp\u003eThis tap is built for blind hole threading in production and maintenance machining environments. The HY-PRO NRT series is engineered for ductile and semi-ductile metals where material displacement rather than chip generation is preferred, reducing the risk of chip packing in blind bores. Typical applications include threading holes in structural components, tooling plates, fixture bodies, and machined housings across a wide range of ferrous and non-ferrous base materials including alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel (material application codes P and N).\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer (1 to 1.5 threads) enables threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eCobalt high-speed steel construction provides heat and wear resistance in tough alloys\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eH6 thread limit delivers consistent, close-tolerance formed threads\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, no coolant-through requirement\u003c\/li\u003e\n  \u003cli\u003eCold-form process eliminates chips, reducing the risk of blind hole packing\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 (material application codes P and N).

Ensure the correct pilot hole diameter for thread forming (larger than a cutting tap pilot hole) is used before tapping. Apply appropriate tapping fluid or cutting oil for the workpiece material, and verify spindle speed and feed rate are set per the tap manufacturer guidelines for the material being threaded. Never reverse a thread forming tap under power without confirming the machine is set for proper back-out feed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 1 to 1.5P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 16\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: 2.938 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.752 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.252 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.286 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: TiCN\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\u003eSeries\u003c\/strong\u003e: HY-PRO NRT (14001)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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: 1400134608\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730043371826,"sku":"1400134608","price":56.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e0a7535aeb52c331c9ab34d6077839_48e80979-391c-4114-a5f8-cb862c4780f3.jpg?v=1788710692","url":"https:\/\/voomisupply.com\/products\/osg-1400134608-thread-forming-tap-3-8-16-unc-bottoming-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
