Part of the Snap Tap series, it carries the CP500 manufacturer grade and features a TiAlN\/TiN PVD coating for extended tool life across a wide range of workpiece materials. The insert has a 29-degree included angle, an inscribed circle of 15.88 mm (0.6252 inches), and a thickness of 6.15 mm (0.2421 inches). Right-hand cutting geometry makes it suitable for standard internal threading operations on lathes and turning centers. It is installed and changed by machinists and CNC tooling technicians.\u003c\/p\u003e\u003cp\u003eThis insert is intended for internal Stub Acme thread forms at 4 TPI on turning and threading equipment. The CP500 grade with PVD coating supports universal workpiece material classifications including cast iron, stainless steel, non-ferrous materials, steel, and superalloys, corresponding to ISO material codes K, M, N, P, and S. It is well suited for production environments where repeatable thread form accuracy and insert longevity are priorities. The Snap Tap series designation indicates compatibility with corresponding Snap Tap insert holders and tooling systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with TiAlN\/TiN PVD coating for wear resistance\u003c\/li\u003e\n\u003cli\u003e4 TPI Internal Stub Acme thread form with 29-degree included angle\u003c\/li\u003e\n\u003cli\u003eCP500 manufacturer grade rated for universal ISO workpiece material groups K, M, N, P, and S\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation for standard internal threading operations\u003c\/li\u003e\n\u003cli\u003eInscribed circle of 15.88 mm (0.6252 inches) and thickness of 6.15 mm (0.2421 inches)\u003c\/li\u003e\n\u003cli\u003eSnap Tap series insert for use with compatible Snap Tap toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Snap Tap series toolholders that accept the 27NR insert style.
