Built from high-speed steel and finished with an elektraLUBE coating, it is engineered for reliable performance in both production and maintenance threading applications. The tap features 3 flutes, a plug chamfer, and a right-hand thread direction. It conforms to a 3B class of fit with an H3 thread limit, producing threads to standard tolerance for general mechanical assemblies. Thread length is 1-21\/32 inches. This tap is installed by machinists, maintenance technicians, and tool-and-die tradespeople working with hand or machine tapping setups.\u003c\/p\u003e\u003cp\u003eThe OSG 1232402 is suited for threading operations in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. The plug chamfer makes it appropriate for through-hole threading where the tap can pass completely through the workpiece. The elektraLUBE coating reduces friction and heat buildup during cutting, extending tool life across repeated use cycles. It is a practical choice for job-shop, maintenance, and light production threading in ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC thread size with right-hand thread direction\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for through-hole threading applications\u003c\/li\u003e\n\u003cli\u003eH3 thread limit, 3B class of fit for standard mechanical assemblies\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eelektraLUBE coating reduces friction and extends tool life\u003c\/li\u003e\n\u003cli\u003e1-21\/32 inches thread length, 3 flutes, no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for threading 1\/2-13 UNC through holes in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel using standard tapping equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed in a properly aligned tap holder or tapping head to prevent thread damage or tap breakage. Power down and secure all workpieces before beginning threading operations. Use appropriate cutting fluid for the material being tapped even when an elektraLUBE coating is present, as supplemental lubrication can extend tool life in demanding applications. Follow applicable shop safety standards and manufacturer guidelines for tapping speeds appropriate to the material and tap size.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\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\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\u003eThread Length\u003c\/strong\u003e: 1-21\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: elektraLUBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Cast Iron, Low-Carbon Steel, Medium-Carbon Steel, High-Carbon Steel, Hardened Steel\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: 0.09 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: 1232402\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51733605744946,"sku":"1232402","price":51.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/656bd294b4e8b2fb5007decf93c266a8.jpg?v=1788756804","url":"https:\/\/voomisupply.com\/products\/osg-1232402-spiral-point-tap-1-2-13-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
