Unlike cutting taps, thread forming taps displace material rather than cut it, producing stronger threads with no chips to clear. This tap is manufactured from powdered metal high-speed steel and carries a TiCN coating for improved wear resistance and lubricity. It features a modified bottoming chamfer with 2 to 2.5 chamfered threads, making it well-suited for blind hole applications where thread engagement close to the bottom of the bore is required. The H3 thread limit and Class 2B fit designation make this tap appropriate for general-purpose fastener work across a range of materials.\u003c\/p\u003e\n\u003cp\u003eThis tap is rated for use in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. It is intended for blind hole threading operations in production and maintenance environments. The EXOTAP VP-NRT series is engineered for use without coolant through the tool, making it compatible with standard tapping setups on CNC machining centers, drill presses, and tapping arms. Right-hand thread direction is standard. The 2-56 UNC size is common in small fastener applications including instrument panels, electronics enclosures, and precision assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design displaces material for chip-free, stronger threads 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 reduces friction and extends tool life across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer with 2 to 2.5 chamfered threads for close-to-bottom thread formation\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit with Class 2B fit for consistent, general-purpose thread quality\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement simplifies setup on standard tapping equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel.

Power down or de-energize any machine spindle before installing or changing the tap. Apply appropriate tapping fluid or cutting oil for the workpiece material to extend tool life and achieve proper thread form. This tap should be installed and operated by a machinist or qualified trade professional familiar with tapping speeds, torque limitations, and thread gauging procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 56\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\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\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: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.437 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.476 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.110 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\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\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: 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\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: 1405001208\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748703994162,"sku":"1405001208","price":77.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/091c6d78a6fab14cf6f26591b58c3c22.jpg?v=1788897010","url":"https:\/\/voomisupply.com\/products\/osg-1405001208-thread-forming-tap-2-56-unc-modified-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
