Identified by ISO code LT16NR115NPTCB and manufactured in grade KC5025, this solid carbide insert carries a PVD-applied TiAlN coating that resists heat and wear during continuous and interrupted threading passes. It cuts at 11.5 threads per inch, matching the NPT taper thread standard used throughout pipe and fitting applications. The right-hand cutting geometry, 3\/8-inch inscribed circle, and 0.1430-inch thickness place it in the standard LT16 insert family. Licensed machinists and CNC operators working on fluid-system components install this insert in compatible laydown-style threading toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for threading internal NPT connections in steel, stainless steel, cast iron, superalloys, and titanium workpieces. Typical applications include machining pipe fittings, valve bodies, manifold ports, and hydraulic or pneumatic system components where a leak-resistant tapered thread is required. The KC5025 grade is engineered to handle the demanding chip loads and workpiece hardness ranges common across these materials, making it a versatile choice for job shops and production environments running mixed-material threading operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in KC5025 grade for wear resistance across a broad material range\u003c\/li\u003e\n  \u003cli\u003ePVD TiAlN coating improves thermal stability and extends tool life in high-speed threading\u003c\/li\u003e\n  \u003cli\u003e11.5 TPI geometry matches NPT taper thread standard for pipe and fitting connections\u003c\/li\u003e\n  \u003cli\u003eRight-hand, internal cutting orientation with CB chipbreaker geometry\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch (9.53 mm) inscribed circle in the LT16 insert size family\u003c\/li\u003e\n  \u003cli\u003eRated for steel, stainless steel, cast iron, superalloys, and titanium workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement laydown threading insert for LT16-series toolholders configured for internal NPT threading applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator. Power down and de-energize the machine before seating or replacing the insert. Secure the insert in its toolholder pocket per the toolholder manufacturer's torque specification and verify seating before running. Confirm correct thread pitch and taper with a calibrated NPT thread gauge after the first pass before proceeding to full production.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: LT16NR115NPTCB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5025\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 11.5 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: CB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1430 inches (3.44 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1551 inches (3.94 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge to Theoretical Edge Length\u003c\/strong\u003e: 0.0430 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace of Insert to Tip Centerline\u003c\/strong\u003e: 0.0590 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.009 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1712671\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727444214066,"sku":"1712671","price":533.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0a3fbc6f0577f217b2ec1200646aa6d1.jpg?v=1788677983","url":"https:\/\/voomisupply.com\/products\/kennametal-1712671-threading-insert-npt-11-5-tpi-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
