It features a plug chamfer, 3 flutes, and is manufactured from high-speed steel with an elektraLUBE coating that reduces friction and extends tool life in production environments. The H5 thread limit maintains close dimensional control for 2B class of fit applications. With a thread length of 1-21\/32 inches and right-hand thread direction, this tap is suited for through-hole tapping operations where chips can be pushed forward and cleared ahead of the cutting edge.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machine shop and manufacturing environments for tapping through-holes in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. The spiral point geometry makes it a practical choice for CNC machining centers, drill presses, and tapping heads where consistent thread quality and chip evacuation are priorities. It is installed and operated by machinists, tooling technicians, and precision manufacturing professionals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward for clean through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eelektraLUBE coating reduces friction and improves tool longevity in production runs\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit provides close tolerance control for 2B class of fit requirements\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\u003e3-flute plug chamfer design balances cutting ease with thread engagement at entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction compatible with standard tapping setups and toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole tapping of 1\/2-13 UNC threads in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel workpieces.

Secure the tap in an appropriate tapping chuck or floating holder to allow for axial compensation and prevent tap breakage. Verify correct spindle speed and feed rate for the workpiece material before engaging the cut. Inspect the tap for wear or chipping between uses, and replace if thread form or coating shows signs of significant degradation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\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\u003eSeries\u003c\/strong\u003e: 105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 1242402\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748208083250,"sku":"1242402","price":57.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c48f8f7b2f96fd912c7a3700a3348230.jpg?v=1788890356","url":"https:\/\/voomisupply.com\/products\/osg-1242402-spiral-point-tap-1-2-13-unc-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
