Part of the EXOTAP VP-NRT series, it uses a cold-forming process rather than cutting, displacing material to create strong, chip-free internal threads. The tap is manufactured from powdered metal high-speed steel and carries a TiCN coating for increased surface hardness and wear resistance. It is configured with a bottoming chamfer of 1 to 1.5 threads, making it well suited for threading close to the bottom of a blind hole. With 80 threads per inch on a 0-80 UNF thread standard, this tap is used in precision small-fastener applications requiring a Class 2B fit and H3 thread limit.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in production and toolroom environments where blind hole threading of small-diameter fastener holes is required. Typical applications include machining of alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum components. The bottoming configuration makes it appropriate for follow-up use after a plug or taper tap has been used to start the thread, or as a standalone tap where full thread depth near the hole bottom is required. It is suitable for CNC machining centers, manual mills, and tapping fixtures without coolant-through capability.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming (chipless) operation eliminates chip packing in blind holes\u003c\/li\u003e\n\u003cli\u003ePowdered metal high-speed steel construction for improved toughness and wear resistance over conventional HSS\u003c\/li\u003e\n\u003cli\u003eTiCN coating increases surface hardness and reduces friction during forming\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer (1 to 1.5 threads) allows threading close to hole bottom\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, Class 2B fit, H3 thread limit\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 thread forming in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Secure the tap in a rigid holder or tapping head to maintain axial alignment and prevent tap breakage in this small diameter. Apply appropriate tapping fluid or cutting oil for the workpiece material to reduce galling during the forming operation. Ensure the workpiece is firmly fixtured before beginning the tapping cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 0-80\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: 80\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\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: Powdered Metal High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.6913 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.3173 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.3500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1410 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.1100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: EXOTAP VP-NRT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.005 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: 1405000108\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743895093554,"sku":"1405000108","price":83.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_3941384e-5327-4eee-9e12-c635a9293eb9.jpg?v=1788851033","url":"https:\/\/voomisupply.com\/products\/osg-1405000108-thread-forming-tap-0-80-unf-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
