Part of the Kennametal Top Notch series, it features a TiAlN finish applied via PVD coating process, which provides wear resistance and thermal stability during high-speed threading. The insert is configured for left-hand cutting with a 60-degree included angle and a 16 TPI pitch, making it suitable for UN-standard internal threads. It carries material grade designations of C2 and C6. The corner radius measures 0.0031 inches (0.08 mm), and the tip-to-top height is 0.1480 inches (3.76 mm).\u003c\/p\u003e\u003cp\u003eThis insert is used in internal threading applications on ferrous and non-ferrous workpieces where UN thread standards apply. The left-hand orientation suits setups requiring reverse-thread cutting or specific spindle configurations. It fits within the Top Notch insert system, which is commonly found in production turning environments including aerospace, automotive, and general machining shops. The insert size 3 designation corresponds to the Top Notch toolholder pocket specification. Minimum order quantity is 5 units; package quantity is 1.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlN PVD coating for extended tool life and heat resistance during internal threading\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting configuration for reverse-thread or specific lathe setups\u003c\/li\u003e\n\u003cli\u003e16 TPI pitch with 60-degree included angle for UN internal thread standards\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0031 inches (0.08 mm) for precise thread form accuracy\u003c\/li\u003e\n\u003cli\u003eKC5025 grade carbide substrate balances toughness and wear resistance\u003c\/li\u003e\n\u003cli\u003eTop Notch series insert size 3 for use with compatible Top Notch toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Kennametal Top Notch series toolholders that accept size 3 NTC-style inserts.
