It carries a TiAlN finish applied via PVD coating process and is manufactured to the KC5010 grade specification. This insert fits the Top Notch toolholding system and handles both internal and external threading operations. The left-hand orientation suits applications where conventional right-hand tooling cannot be used. Machinists and CNC operators use this insert for high-production threading in steel and other ferrous materials where wear resistance and edge retention are critical.\u003c\/p\u003e\n\u003cp\u003eThe 2217646 is suited for lathe-based threading operations in production and job-shop environments. Its NTB insert style and size 3 designation are specific to the Top Notch quick-change insert system. The 52-degree included angle is standard for American Buttress thread profiles used in pipe fittings, hydraulic components, and heavy industrial assemblies. Both internal and external thread forms are supported with this single insert.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlN finish via PVD coating for extended tool life in ferrous and hardened materials\u003c\/li\u003e\n  \u003cli\u003eKC5010 manufacturer grade optimized for threading applications\u003c\/li\u003e\n  \u003cli\u003e12 TPI pitch supports both internal and external American Buttress thread cutting\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert orientation for reverse-direction threading setups\u003c\/li\u003e\n  \u003cli\u003e52-degree included angle matches American Buttress thread profile standard\u003c\/li\u003e\n  \u003cli\u003eTop Notch Series NTB style for secure, repeatable insert indexing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch Series NTB-style toolholders accepting size 3 inserts.
