It features 4 flutes and a regular hook geometry, giving it the chip clearance and cutting action needed for clean, accurate threads in production and maintenance applications. Built from high-speed steel (HSS) with a bright\/uncoated finish, it runs without coating interference and can be resharpened when worn. Overall length is 2.126 inches, with a 0.75-inch thread length. Licensed plumbers, pipefitters, and machinists reach for this tap when threading ports, fittings, and couplings that follow NPS dimensional standards.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading 1\/8-27 NPS pipe connections in residential and commercial plumbing, HVAC, and mechanical piping applications. It performs in aluminum, carbon steel, cast iron, and hardened steel. The 0.4375-inch shank diameter and 0.3280-inch square size fit standard tap handles and machine holders. Typical use includes threading raw stock, nipples, fittings, and manifold ports where a standard NPS pipe thread form is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/8-27 NPS thread size and profile for standard pipe fitting connections\u003c\/li\u003e\n  \u003cli\u003e4-flute regular hook design promotes chip evacuation and thread accuracy\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction supports use across aluminum, carbon steel, cast iron, and hardened steel\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish allows for easy resharpening and is compatible with cutting fluids\u003c\/li\u003e\n  \u003cli\u003eCompact 2.126-inch overall length fits tight working clearances\u003c\/li\u003e\n  \u003cli\u003eStandard shank and square dimensions compatible with common tap handles and machine setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application requiring a 1\/8-27 NPS internal pipe thread.

Always secure the workpiece and apply a suitable cutting fluid for the material being tapped to extend tool life and improve thread quality. Back the tap off periodically to break chips, particularly in deeper holes or tougher materials. Follow applicable IFGC and IPC guidelines when threading pipe connections in gas or plumbing systems.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/8-27\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 27\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHook\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Profile\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.126 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.3280 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: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Carbon Steel, Cast Iron, Hardened Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 109\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: 1330100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739431272754,"sku":"1330100","price":67.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc7222b0d77d873ade8f2f8e681bfd69_5e1abfcd-78e8-4cd6-8a2b-20baf6fda347.jpg?v=1788814511","url":"https:\/\/voomisupply.com\/products\/osg-1330100-nps-pipe-tap-1-8-27-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
