The spiral point geometry pushes chips forward ahead of the tap, preventing chip packing in through-hole applications. Built from high-speed steel with a bright uncoated finish, this plug chamfer tap features 3 flutes and an H2 thread limit for controlled fit tolerances. It measures 2.938 inches overall length with a 0.787 inch thread length and a 0.381 inch shank diameter. This tap is installed by machinists, maintenance technicians, and tooling professionals working on production or repair operations.\u003c\/p\u003e\n\u003cp\u003eThe OSG 1226800 is suited for through-hole tapping in residential, commercial, and industrial settings. Its material application range includes aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. The plug chamfer provides a gradual lead-in, making it appropriate for both machine tapping and hand tapping operations where the hole passes fully through the workpiece.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point design pushes chips forward for clean through-hole tapping\u003c\/li\u003e\n  \u003cli\u003e3\/8-24 UNF thread form with right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit for consistent, controlled fit tolerances\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles a broad range of ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for gradual thread engagement and reduced tap breakage risk\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating interference with tight tolerance fits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threading tool for any application requiring a 3\/8-24 UNF right-hand internal thread in through-hole workpieces across compatible materials including aluminum, cast iron, and low- through high-carbon steels.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and use this tap with a properly aligned tapping head, drill press, or CNC machine to avoid tap breakage from misalignment. Ensure the pilot hole is drilled to the correct tap drill diameter for 3\/8-24 UNF before tapping. Use appropriate cutting fluid for the material being tapped to extend tool life and improve thread finish. Secure the workpiece fully before operation and confirm spindle speed is appropriate for the material and tap size.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\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: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.938 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.787 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 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\u003eSeries\u003c\/strong\u003e: 105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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: 1226800\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727440707890,"sku":"1226800","price":33.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a5303da95d242294f8d29d031754d23.jpg?v=1788677967","url":"https:\/\/voomisupply.com\/products\/osg-1226800-spiral-point-tap-3-8-24-unf-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
