It produces 8-32 UNC threads with a plug chamfer, 2-flute spiral point geometry that pushes chips forward ahead of the cut to keep flutes clear during through-hole tapping. The tap is manufactured from high-speed steel and coated with TiCN (Titanium Carbonitride) for improved surface hardness and heat resistance. The H3 thread limit holds tolerances required for a 2B class of fit, making it suitable for standard fastener applications where consistent thread quality is critical. Overall length is 2.125 inches with a shank diameter of 0.168 inches.\u003c\/p\u003e\u003cp\u003eThis tap is suited for through-hole tapping operations in production and job-shop environments. It handles a broad material range including aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. Right-hand cut, no coolant-through design. Machinists, tool-and-die makers, and maintenance technicians use this tap in drill presses, CNC machining centers, and tapping machines where chip evacuation in through-holes is a priority.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-32 UNC thread form, 2B class of fit with H3 thread limit for standard tolerance control\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward — optimized for through-hole applications\u003c\/li\u003e\n\u003cli\u003eTiCN coating increases surface hardness and extends tool life in abrasive materials\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides toughness across a wide material range\u003c\/li\u003e\n\u003cli\u003ePlug chamfer (3-5 thread lead) for general-purpose through-hole starting\u003c\/li\u003e\n\u003cli\u003eCompatible with aluminum, cast iron, low-, medium-, and high-carbon steel, and hardened steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for through-hole tapping of 8-32 UNC threads in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall in a tap holder, tapping head, or rigid CNC spindle with proper alignment to prevent tap breakage. Secure the workpiece before operation and use appropriate cutting fluid for the material being tapped. Follow shop safety practices and machine manufacturer guidelines for spindle speed and feed rate when running in a machining center. Inspect the tap for wear or chipping before each use — a worn tap in hardened materials increases the risk of breakage and thread damage.\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: TiCN\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\u003eInterrupted Thread\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.014 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 105\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: 1212808\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51735255482674,"sku":"1212808","price":33.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13a9200db174dd196822b23d0c3903ee.jpg?v=1788771037","url":"https:\/\/voomisupply.com\/products\/osg-1212808-spiral-point-tap-8-32-unc-ticn-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
