Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction during threading operations. The plug chamfer provides a gradual lead-in, making it well suited for through-hole applications. With 2 flutes and an H3 thread limit, it produces Class 2B fit threads that meet standard fastener assembly tolerances. Overall length is 2.125 inches with a shank diameter of 0.168 inches and a thread length of 0.39 inches.\u003c\/p\u003e\u003cp\u003eThis tap is used in machine shop, maintenance, and field repair applications where 8-32 UNC threads are required in through-hole configurations. It is appropriate for use in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. The TiN coating makes it a practical choice when tapping abrasive or harder materials where uncoated HSS would wear more rapidly. Machinists, tool-and-die technicians, and maintenance mechanics commonly specify this tap for production and repair work on threaded fastener holes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-32 UNC thread form with H3 thread limit for consistent Class 2B fit\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends tool life compared to uncoated HSS\u003c\/li\u003e\n\u003cli\u003ePlug chamfer suits through-hole threading applications\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, compatible with standard tapping equipment\u003c\/li\u003e\n\u003cli\u003e2-flute spiral point design pushes chips forward ahead of the tap\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement simplifies setup on standard equipment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use spiral point tap for any application requiring 8-32 UNC, Class 2B, H3 thread limit in through-hole configurations across aluminum, cast iron, and carbon or hardened steel workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed and driven by licensed machinists or qualified maintenance mechanics using a standard tap handle, tapping head, or CNC machine tool holder. Always ensure the workpiece is securely fixtured and the pilot hole diameter matches the recommended drill size for 8-32 UNC before beginning the threading operation. Apply a suitable cutting fluid for the workpiece material to minimize heat buildup and extend tap life. Do not reverse the tap under power without confirming the machine or handle supports back-out without binding.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\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\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.39 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Cast Iron, Hardened Steel, High-Carbon Steel, Low-Carbon Steel, Medium-Carbon Steel\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: 1212805\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51753177317682,"sku":"1212805","price":30.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e3750d7b25908857607b151dbd1760ce.jpg?v=1788933546","url":"https:\/\/voomisupply.com\/products\/osg-1212805-spiral-point-tap-8-32-unc-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
