Built from solid carbide and finished with a PVD-applied TiAlN\/TiN coating, this insert carries the CP500 grade designation and is part of the Snap-Tap series. It cuts a partial profile 60-degree thread form and covers a pitch range of 0.50 mm to 1.50 mm, corresponding to 48 to 16 TPI. The inscribed circle measures 9.53 mm and insert thickness is 3.47 mm (0.1366 inches). Machinists and CNC turning specialists use this insert for precision thread cutting in a range of workpiece materials classified under ISO material groups K, M, P, and S.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal threading applications on CNC lathes and turning centers where left-hand thread forms are required. The partial profile 60-degree geometry covers unified and metric thread standards within the supported pitch range, making it a practical tooling choice for shops running mixed-material jobs. The universal workpiece material rating means it performs across cast iron, steel, stainless, and high-temperature alloys within appropriate cutting parameter windows.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCP500 carbide grade with PVD TiAlN\/TiN coating for wear resistance across multiple material groups\u003c\/li\u003e\n\u003cli\u003eLeft-hand internal partial profile 60-degree thread form\u003c\/li\u003e\n\u003cli\u003eCovers 48 to 16 TPI pitch range (0.50 mm to 1.50 mm)\u003c\/li\u003e\n\u003cli\u003e16NL insert style in the Snap-Tap series for secure, repeatable seating\u003c\/li\u003e\n\u003cli\u003eCompatible with ISO material groups K, M, P, and S\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0800 inches for consistent thread root profile\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Snap-Tap series replacement insert for toolholders accepting the 16NL insert style.
