Designated by the ISO code 11IR18NPT, it profiles 60-degree NPT threads at 18 threads per inch using a right-hand cutting orientation. The insert carries the TT9030 manufacturer grade and features a PVD-applied TiAlN coating that improves wear resistance and extends tool life when threading steel, stainless steel, and cast iron. With a corner radius of 0.002 inches and a 1\/4-inch inscribed circle, it delivers precise thread form on internal bores with minimal setup variation.\u003c\/p\u003e\u003cp\u003eThis insert is suited for shops and field machinists producing or repairing internal NPT pipe threads in ferrous and non-ferrous workpieces. Typical applications include threading pipe fittings, valve bodies, manifolds, and pressure-containing components where NPT 60-degree thread standards are required. The TiAlN PVD coating also makes it viable for secondary operations on hard materials, superalloys, and titanium where heat buildup at the cutting edge is a concern. It is sold individually and typically ordered in minimum quantities of five.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eISO code 11IR18NPT for internal NPT threads at 18 TPI with a 60-degree included angle\u003c\/li\u003e\n\u003cli\u003eTT9030 carbide grade with PVD TiAlN coating for extended wear life in steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation, no chipbreaker, NPT Regular Type series\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.002 inches for clean, accurate thread form\u003c\/li\u003e\n\u003cli\u003eCompatible with primary workpiece materials: steel, stainless steel, and cast iron (ISO P, M, K)\u003c\/li\u003e\n\u003cli\u003eSecondary material capability: hard materials, superalloys and titanium, and non-ferrous metals (ISO H, S, N)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a laydown threading insert for toolholders accepting the 11IR insert style.

Ensure the machine spindle is fully stopped and locked out before seating or replacing the insert. Use the correct torque wrench and insert screw specified by the toolholder manufacturer  -  do not overtighten, as carbide inserts are brittle and will crack under excess clamping force. Confirm thread pitch and insert orientation against the workpiece drawing before beginning the threading cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: 11IR18NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 11IR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TT9030\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT 60 Degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: 1.41 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge to Theoretical Edge Length\u003c\/strong\u003e: 0.039 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace of Insert to Tip Centerline\u003c\/strong\u003e: 0.031 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.126 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Teeth Per Side\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: NPT Regular Type\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Hard Material, Superalloys and Titanium, Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.28 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: INGERSOLL CUTTING TOOLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5902041\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INGERSOLL CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51986165399858,"sku":"5902041","price":180.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3f917485dadc473917a615610fecba6.jpg?v=1789985961","url":"https:\/\/voomisupply.com\/products\/ingersoll-cutting-tools-5902041-threading-insert-18-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
