It features a plug chamfer, three flutes, and a right-hand thread direction with an H3 thread limit and 3B class of fit. The tap is manufactured from high-speed steel and finished with a titanium carbonitride (TiCN) coating, which improves wear resistance and reduces heat buildup during cutting. Overall length is 3.375 inches with a thread length of 0.941 inches and a shank diameter of 0.367 inches. Machinists and tool-and-die professionals use this tap in production and maintenance machining environments.\u003c\/p\u003e\u003cp\u003eThis tap is suited for through-hole threading operations in a wide range of materials including aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. The spiral point geometry pushes chips forward ahead of the cutting zone, making it well suited for production runs and CNC tapping where through-holes allow chip evacuation. It belongs to OSG Series 105 and does not require coolant-through capability, making it compatible with standard tapping setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward for efficient through-hole tapping\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves surface hardness and extends tool life across abrasive materials\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction handles a broad range of ferrous and non-ferrous workpiece materials\u003c\/li\u003e\n\u003cli\u003eH3 thread limit and 3B class of fit for standard tolerance through-hole threads\u003c\/li\u003e\n\u003cli\u003ePlug chamfer (3-5 thread lead) for general-purpose starting in pre-drilled through holes\u003c\/li\u003e\n\u003cli\u003eNo interrupted thread geometry and no coolant-through requirement simplifies setup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 1\/2-13 UNC right-hand threads in through-hole applications across 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\u003eThis tap is installed and operated by machinists using a standard tap wrench, tapping head, or CNC rigid tapping cycle. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for 1\/2-13 UNC before beginning the tapping operation. Apply an appropriate cutting fluid for the workpiece material to reduce friction and extend tap life. Inspect the tap for wear or chipping before each use and replace if cutting edges show deterioration.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 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: 3\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: 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\u003eCoating\u003c\/strong\u003e: TiCN (Titanium Carbonitride)\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: 3.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.941 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 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: 0.115 pounds\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: 1232408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739992391986,"sku":"1232408","price":58.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f6b665465ad8a2a8b7e44b23cb03bbe.jpg?v=1788821229","url":"https:\/\/voomisupply.com\/products\/osg-1232408-spiral-point-tap-1-2-13-unc-ticn-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
