Running in the KC5025 grade with a PVD-applied TiAlN coating, this insert handles right-hand internal threading at 14 threads per inch. The 1\/4-inch (6.35 mm) inscribed circle and 0.126-inch thickness match standard LT11NR toolholder pockets. KC5025 is engineered for toughness and wear resistance in interrupted and continuous threading cuts, making it a reliable choice for production threading environments where consistent thread form and tool life matter.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for threading steel, stainless steel, cast iron, superalloys, and titanium workpieces. It is primarily used in CNC turning centers and manual lathes equipped with LT11-style threading toolholders. Typical applications include pipe fitting production, manifold threading, and any operation requiring accurate NPT taper thread profiles in metalworking shops, oilfield component manufacturing, and industrial machining environments. The NPT thread standard makes this insert appropriate for producing pressure-tight tapered pipe thread connections common in fluid and gas systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate in KC5025 grade for toughness and extended wear resistance\u003c\/li\u003e\n  \u003cli\u003ePVD TiAlN coating improves heat resistance and reduces crater wear during threading\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, internal NPT thread form at 14 TPI for standard tapered pipe threads\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch inscribed circle with 0.126-inch thickness fits LT11NR toolholder pockets\u003c\/li\u003e\n  \u003cli\u003eCompatible workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eISO code LT11NR14NPT for precise toolholder and insert matching\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in LT11NR-style laydown threading toolholders accepting inserts with a 1\/4-inch inscribed circle and 0.126-inch thickness.

Seat the insert fully in the toolholder pocket and torque the clamping screw according to the toolholder manufacturer's specifications. Inspect the insert pocket for chips or debris before seating to avoid insert rocking or premature breakage. Confirm thread pitch and hand orientation match the workpiece requirements before initiating a threading cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: 11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: LT11NR14NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5025\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 14 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/4 inch (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.126 inches (3.04 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.128 inches (3.25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge to Theoretical Edge Length\u003c\/strong\u003e: 0.031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace of Insert to Tip Centerline\u003c\/strong\u003e: 0.039 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\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0031 pounds\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: 1743967\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733283176754,"sku":"1743967","price":589.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b6e426891b32c839730b49c7217aee9b.jpg?v=1788753555","url":"https:\/\/voomisupply.com\/products\/kennametal-1743967-threading-insert-npt-14-tpi-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
