Unlike cutting taps, thread forming taps displace material rather than remove it, producing stronger threads with no chips to clear. This tap features a semi-bottoming chamfer, an H5 thread limit, and a cobalt construction that handles demanding applications where standard high speed steel taps fall short. The overall length is 3.15 inches (80 mm) with a thread length of 0.39 inches (11 mm). A V-coating finish reduces friction and extends tool life in production environments. It is installed by machinists and tool-room technicians.\u003c\/p\u003e\u003cp\u003eThis tap is suited for production and maintenance threading operations in both shop and field environments. The semi-bottoming chamfer allows threading close to the bottom of a blind hole while still providing a lead-in for alignment. Compatible material applications include aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloy, and titanium. The 2B class of fit meets standard tolerance requirements for general-purpose 8-32 UNC threaded assemblies. This tool is appropriate for CNC tapping, drill press setups, and hand-tapping operations requiring tight thread tolerance control.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design displaces material for chip-free, stronger threads\u003c\/li\u003e\n\u003cli\u003eCobalt construction provides heat and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eSemi-bottoming chamfer allows threading near the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eH5 thread limit for consistent 2B class of fit tolerance control\u003c\/li\u003e\n\u003cli\u003eV-coating finish reduces friction and extends tool life\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, 32 threads per inch, 8-32 UNC standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for threading 8-32 UNC holes in aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloy, and titanium workpieces requiring a 2B class of fit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by machinists using a tap wrench, tapping head, or CNC spindle with appropriate torque control. Always ensure the pilot hole diameter is sized correctly for thread forming taps, as these require a larger pilot hole than cutting taps for the same thread size. Power down or de-energize any machine tool before loading or changing tooling. Follow applicable shop safety standards and manufacturer pilot hole charts for thread forming applications to avoid tap breakage or oversize threads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: H5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Semi-Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.15 inches (80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.39 inches (11 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 22 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.85 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.131 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16255\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 1625583225\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51735180345650,"sku":"1625583225","price":123.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3299a5522130241ca27ef656891389e6_2d2b78e2-8da5-4e0e-a20d-7e572b2b0003.jpg?v=1788770089","url":"https:\/\/voomisupply.com\/products\/osg-1625583225-thread-forming-tap-8-32-unc-2b-h5","provider":"Voomi Supply","version":"1.0","type":"link"}
