Manufactured to the LT16ERAG60CB geometry in the KC5025 grade, this insert features a PVD-applied TiAlN coating that supports sustained cutting performance in a range of workpiece materials. The right-hand cutting orientation and partial profile 60-degree thread form make it suited to general external threading work across a wide range of thread pitches from 48 to 8 TPI (0.50 to 3.00 mm pitch). The 3\/8 inch inscribed circle and 0.143 inch thickness conform to standard LT16 toolholder pockets.\u003c\/p\u003e\u003cp\u003eThis insert is used in production and job-shop CNC turning environments where external metric and unified threads are cut using a partial-profile strategy, allowing a single insert to cover a range of thread pitches rather than being dedicated to one. Typical applications include threading of steel, alloy steel, and similar ferrous materials. The CB chipbreaker geometry assists with chip control during threading passes. Installation requires a compatible LT16-series laydown threading toolholder. This insert is sold individually, with a minimum order quantity of 10 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePVD TiAlN coating applied via PVD process for wear resistance and thermal stability\u003c\/li\u003e\n\u003cli\u003ePartial profile 60-degree thread form covers 48 to 8 TPI and 0.50 to 3.00 mm pitch range\u003c\/li\u003e\n\u003cli\u003eRight-hand external cutting geometry for standard CNC lathe threading operations\u003c\/li\u003e\n\u003cli\u003eKC5025 carbide grade engineered for threading in ferrous and alloy materials\u003c\/li\u003e\n\u003cli\u003eCB chipbreaker design aids chip control during multi-pass threading cycles\u003c\/li\u003e\n\u003cli\u003eLT16 laydown geometry fits standard LT16-series toolholder pockets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in LT16-series laydown threading toolholders that accept a 3\/8 inch inscribed circle insert with a 0.1551 inch hole diameter.
