The set covers tap thread sizes from 3 millimeters up to 12 millimeters, making it a practical range for general machining and repair work in the trades. Each tap features a plug chamfer, which provides a balance between a starting taper and a full bottoming profile, suited for through-holes and most standard tapping applications. Taps are manufactured from carbon steel with a bright, uncoated finish. Right-hand thread cutting is standard throughout the set. Machinists, pipefitters, and maintenance technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis tap set is used in metalworking applications where metric internal threads need to be cut or restored. Common scenarios include fabrication shops, mechanical maintenance, HVAC equipment repair involving threaded fittings, and plumbing fixture work requiring metric thread profiles. The plug chamfer style makes these taps suitable for production and repair use where the tap can be started with moderate alignment effort. The 3 mm to 12 mm range addresses the most frequently encountered metric thread sizes in light to medium industrial work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCovers metric tap sizes from 3 mm through 12 mm in a single set\u003c\/li\u003e\n\u003cli\u003ePlug chamfer profile balances easy starting with efficient thread cutting\u003c\/li\u003e\n\u003cli\u003eCarbon steel construction provides adequate hardness for tapping mild steel, aluminum, brass, and similar materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish allows direct inspection of tap condition\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction matches standard metric fastener convention\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose metric tap set suitable for hand tapping and machine tapping applications requiring right-hand plug taps in the 3 mm to 12 mm thread size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTap installation is typically performed by machinists or maintenance technicians using a tap wrench or tapping attachment. Always use cutting fluid appropriate to the workpiece material to extend tap life and improve thread quality. Ensure the workpiece is securely fixtured before beginning to prevent tap breakage. Inspect each tap for wear or damage before use and replace any tap that shows chipping or excessive wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Tap Thread Size\u003c\/strong\u003e: 3 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Tap Thread Size\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\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\u003eMaterial\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 2.15 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 14.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.75 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: 1840234\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":51538398642482,"sku":"1840234","price":498.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/34071218b06b76dd49855fd07920d38b.jpg?v=1785824512","url":"https:\/\/voomisupply.com\/products\/irwin-1840234-metric-tap-set-3mm-to-12mm-carbon-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
