Made from tough High-Speed Steel (HSS), this bottoming tap features a short chamfer to allow full thread cutting close to the bottom of blind holes. It’s ideal for producing tight-fitting parallel threads in non-pressurized pipe or conduit applications, such as electrical fittings, low-pressure systems, and mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features \u0026amp; Benefits\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBottoming Chamfer\u003c\/strong\u003e – 1–2 threads engaged, suitable for threading to the bottom of blind holes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Thread Type:\u003c\/strong\u003e NPS (National Pipe Straight) – Parallel thread profile for low-pressure and mechanical fits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStraight Flute\u003c\/strong\u003e – Ideal for short-chipping materials and general-purpose tapping.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Speed Steel (HSS)\u003c\/strong\u003e – Delivers toughness, edge retention, and wear resistance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRight-Hand Threading\u003c\/strong\u003e – Compatible with standard tapping directions and setups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatile Applications\u003c\/strong\u003e – Use in electrical, conduit, and low-pressure piping or assembly.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart No:\u003c\/strong\u003e 5810323\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type:\u003c\/strong\u003e NPS (National Pipe Straight)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size:\u003c\/strong\u003e 1\/8″ NPS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Style:\u003c\/strong\u003e Bottoming Tap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer:\u003c\/strong\u003e Bottom (1–2 threads)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type:\u003c\/strong\u003e Straight Flute\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction:\u003c\/strong\u003e Right-Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Blind-hole tapping for straight pipe thread assemblies\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard:\u003c\/strong\u003e ANSI \/ Unified Pipe Thread\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eWhy Choose the SOMTA 5810323 Bottom Tap?\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Threading\u003c\/strong\u003e – Creates clean, accurate pipe threads with tight parallel fits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBottoming Design\u003c\/strong\u003e – Excellent for threading to near-bottom depth in blind holes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Construction\u003c\/strong\u003e – HSS withstands industrial use with minimal wear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrusted in Industry\u003c\/strong\u003e – Ideal for workshops, MRO, and custom fitting work.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe \u003cstrong\u003eSOMTA 5810323\u003c\/strong\u003e NPS 1\/8″ bottom tap offers professional-grade performance for precision threading of straight pipe connections—ensuring secure and reliable fits in mechanical and conduit assemblies.\u003c\/p\u003e","brand":"SOMTA","offers":[{"title":"Default Title","offer_id":51251835109412,"sku":"5810323","price":62.25,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0803\/5598\/3396\/files\/somta-taps-dies-somta-series-581-hss-straight-flute-parallel-pipe-bottom-finishing-tap-nps-1-8-x-27-tpi-4749504735969-1198292887.png?v=1786525543","url":"https:\/\/www.layerspecdynamics.com\/de\/products\/somta-series-581-hss-nps-1-8-bottom-tap-straight-flute-pipe-thread","provider":"LayerSpec Dynamics","version":"1.0","type":"link"}
