Manufactured to the LT16NRG60 insert style in the KC5010 carbide grade, this insert carries a PVD-applied TiAlN coating for improved wear resistance and tool life at elevated cutting temperatures. It produces a partial profile 60-degree thread form for right-hand internal threading across a pitch range of 14 to 8 threads per inch (1.75 to 3.00 mm pitch). The inscribed circle measures 3\/8 inch (9.53 mm) and the insert thickness is 0.1430 inches (3.44 mm). Machinists and CNC tooling technicians install this insert in compatible LT-style threading toolholders on manual or CNC turning equipment.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal threading operations in production turning environments, including job shops and high-volume machining cells. The 14-8 TPI range covers common unified and metric-equivalent thread pitches found in hydraulic fittings, pipe threads, and fastener applications. The KC5010 grade with TiAlN PVD coating performs well in steels, stainless steels, and cast irons where thermal resistance and edge retention are priorities. Right-hand cutting geometry makes this insert compatible with conventional lathe rotation for standard internal bore threading.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction in KENNAMETAL KC5010 grade for consistent edge performance\u003c\/li\u003e\n\u003cli\u003ePVD TiAlN coating provides thermal and oxidation resistance during high-speed threading\u003c\/li\u003e\n\u003cli\u003ePartial profile 60-degree thread form cuts a range of thread pitches without changing inserts\u003c\/li\u003e\n\u003cli\u003eRight-hand internal cutting geometry for standard CNC lathe boring bar applications\u003c\/li\u003e\n\u003cli\u003ePitch range of 14-8 TPI (1.75-3.00 mm) covers a broad spectrum of common thread sizes\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0059 inches (0.15 mm) for defined thread root geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement threading insert for LT16-style internal threading toolholders used in CNC turning and lathe boring bar applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and replacement of threading inserts should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before changing inserts. Use the appropriate torx or hex key specified for the toolholder clamp screw, and ensure the insert seats fully and evenly in the pocket before tightening. Inspect the toolholder pocket for chips or damage before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16NR\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: KC5010\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: Partial Profile 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\u003eThreads Per Inch\u003c\/strong\u003e: 14-8 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch Range\u003c\/strong\u003e: 1.75-3.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (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\u003eCorner Radius\u003c\/strong\u003e: 0.0059 inches (0.15 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\u003eWeight\u003c\/strong\u003e: 0.0106 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1724420\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742856479026,"sku":"1724420","price":624.76,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/81499fa63f92b13c861cb071daa8552b.jpg?v=1788839876","url":"https:\/\/voomisupply.com\/products\/kennametal-1724420-threading-insert-lt16nrg60-kc5010-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
