Unlike cutting taps, this plug-chamfer forming tap displaces material rather than removing chips, producing stronger threads with a superior finish. It is manufactured from cobalt high speed steel with a V-coat finish and carries an H5 thread limit for tight tolerance control. The 8-32 UNC configuration with a 2B class of fit makes it a standard choice for fastener holes in light industrial and precision mechanical assemblies. Licensed machinists and tool-and-die professionals are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis tap suits through-hole threading operations at 8-32 UNC in a broad spectrum of materials including aluminum, cast aluminum, carbon steel, alloy steel, die steel, stainless steel, high-nickel alloys, and titanium. The plug chamfer provides 4 to 4.5 threads of lead, making it well suited for both CNC tapping centers and manual tapping in production and maintenance environments. Its compact overall length of 2.4803 inches fits standard tap holders and quick-change systems used in shop floor applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming (chipless) design produces stronger, work-hardened threads versus cut taps\u003c\/li\u003e\n  \u003cli\u003eCobalt high speed steel construction for heat and wear resistance in tough alloys\u003c\/li\u003e\n  \u003cli\u003eV-coat finish reduces friction and extends tool life in high-speed applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 4 to 4.5 chamfered threads for reliable thread lead-in\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit for precise 2B class of fit tolerances\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; through-hole application\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole thread forming in aluminum, cast aluminum, hardened steel, carbon steel, alloy steel, die steel, stainless steel, high-nickel alloy, and titanium workpieces.

Ensure adequate lubrication or cutting fluid is applied, as forming taps generate higher torque than cutting taps, particularly in stainless steel and titanium. Power down or de-energize the machine spindle before installing or removing the tap from the holder. Follow shop safety protocols and applicable OSHA machining standards when operating tapping equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 4 to 4.5P\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: Through-Hole Threading\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\/Finish\u003c\/strong\u003e: V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.4803 inches (63 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.3740 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.8270 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1680 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.1310 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.2500 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: 16250\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Name\u003c\/strong\u003e: EXOPRO XPF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 1625083245\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51755677155634,"sku":"1625083245","price":94.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97a1414e31a570fbb064964d71eb3551_e66e3a0e-9e89-4839-99d0-df74de3c77d4.jpg?v=1788957987","url":"https:\/\/voomisupply.com\/products\/osg-1625083245-thread-forming-tap-8-32-unc-plug","provider":"Voomi Supply","version":"1.0","type":"link"}
