Built from powdered metal high-speed steel and finished with a TiCN coating, it delivers extended tool life in demanding production environments. The modified bottoming chamfer with 2 to 2.5 chamfered threads allows threading close to the bottom of a blind hole. Overall length is 2 inches with a thread limit of H3 and a right-hand thread direction. It is sized for use with standard tapping drivers and holders compatible with a 0.141-inch shank diameter. Licensed machinists and maintenance technicians working in metal fabrication, HVAC equipment manufacturing, and related trades will find this tap suited to precision blind-hole applications.\u003c\/p\u003e\n\u003cp\u003eThis tap is engineered for blind hole threading in a broad range of metallic materials including alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. Its cold-forming action is especially well suited to high-volume production threading where chip control is a priority and thread strength is critical. The EXOTAP VP-NRT series designation indicates compatibility with OSG's high-performance tapping line designed for through-spindle and flood coolant applications, though this tap does not feature internal coolant delivery. It is a practical choice for job shops, assembly lines, and field maintenance operations requiring consistent 6-32 UNC thread quality.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design eliminates chips, reducing tap breakage risk in blind holes\u003c\/li\u003e\n  \u003cli\u003eTiCN coating increases surface hardness and reduces friction for longer service life\u003c\/li\u003e\n  \u003cli\u003ePowdered metal high-speed steel substrate provides superior wear resistance over conventional HSS\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2 to 2.5 chamfered threads) enables threading close to hole bottom\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit provides appropriate tolerance for Class 3B fit requirements\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, compatible with standard tapping equipment\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.

Power down and de-energize any tapping machine or CNC spindle before changing or inspecting tooling. Use appropriate cutting fluid or tapping compound recommended for the workpiece material to maximize tool life, even though this tap does not require through-coolant. Verify correct pilot hole diameter for thread forming before use, as cold-forming taps require a different pilot hole size than cutting taps for the same thread size.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 6-32\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: 32\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\u003eClass of Fit\u003c\/strong\u003e: 3B\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: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.3701 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.685 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: 0.11 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: 0.013 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: 1405003608\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727889072434,"sku":"1405003608","price":67.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/23d680ab7b704d6ea5ca80343fa9dfaa.jpg?v=1788684061","url":"https:\/\/voomisupply.com\/products\/osg-1405003608-thread-forming-tap-6-32-unc-modified-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
