The set includes both taps and hex dies machined from carbon steel with a bright finish for corrosion resistance and dimensional consistency. An adjustable die stock and an adjustable hand tap wrench are included, making the set self-contained for field or shop use. Licensed plumbers, pipefitters, HVAC technicians, and maintenance mechanics use this set to cut, clean, and restore external and internal threads on pipe fittings, fasteners, and mechanical components. The plastic carry case keeps pieces organized and protects cutting edges between uses.\u003c\/p\u003e\u003cp\u003eThis tap and die set is suited for trade applications requiring both pipe threads (NPT) and machine threads (UNC and UNF) in a single kit. NPT coverage makes it directly applicable to plumbing and HVAC piping work where threaded pipe connections are cut or restored on the job. The UNC and UNF dies and taps address fastener thread repair and fabrication across general mechanical and electrical trade work. Die thread sizes included are 1-14, 1-8, 1\/4-18, 3\/4-10, 3\/4-16, 5\/8-11, 5\/8-18, 7\/8-14, 7\/8-9, 9\/16-12, and 9\/16-18.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e25-piece set covering NPT, UNC, and UNF thread standards from 1\/4-18 to 1-14\u003c\/li\u003e\n\u003cli\u003eCarbon steel construction on both taps and dies for durability across standard trade materials\u003c\/li\u003e\n\u003cli\u003eBright finish on all cutting tools for corrosion resistance and easy visual inspection\u003c\/li\u003e\n\u003cli\u003eHex die shape for consistent wrench engagement and controlled torque application\u003c\/li\u003e\n\u003cli\u003eIncludes adjustable die stock and adjustable hand tap wrench — no separate handle purchase required\u003c\/li\u003e\n\u003cli\u003ePlastic carry case organizes all 25 pieces and protects cutting edges in tool storage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting and restoring NPT pipe threads and UNC and UNF machine threads on standard carbon steel, iron, and similar materials commonly encountered in plumbing, HVAC, and mechanical trade work.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTap and die work should be performed by qualified tradespeople familiar with thread standards and proper cutting technique. Always apply appropriate cutting oil to extend tool life and produce clean threads. On pipe systems, depressurize and drain the line completely before cutting or restoring any threaded connection. Follow applicable codes — IFGC for gas piping threads, IPC for water service threads — when cutting pipe threads for pressurized systems.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Tap Thread Size\u003c\/strong\u003e: 1\/4-18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Tap Thread Size\u003c\/strong\u003e: 1-14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Die Thread Size\u003c\/strong\u003e: 1\/4-18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Die Thread Size\u003c\/strong\u003e: 1-14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standards\u003c\/strong\u003e: NPT, UNC, UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDie Shape\u003c\/strong\u003e: Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Material\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDie Material\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Adjustable Die Stock, Adjustable Hand Tap Wrench\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Type\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 13.7 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: IRWIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 97094ZR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":51541037187378,"sku":"97094ZR","price":729.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/191662755.jpg?v=1785867635","url":"https:\/\/voomisupply.com\/products\/irwin-97094zr-tap-die-set-25-pc-npt-unc-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
