Part of the Kennametal Top Notch series, it carries the KC5025 manufacturer grade with a PVD-applied TiAlN finish for improved wear resistance and tool life in demanding threading operations. The insert is right-hand, NAS-style, and cuts at a 29-degree included angle with an internal pitch of 5 TPI. With a cutting tip width of 0.0791 inches and a tip-to-top dimension of 0.1492 inches, this insert is built for precise, repeatable thread form geometry on ferrous and non-ferrous materials graded C2 and C6.\u003c\/p\u003e\u003cp\u003eThis insert is suited for use in CNC lathes and manual turning centers where Stub Acme threads are required. Stub Acme profiles are commonly found in lead screws, linear actuators, and mechanical power transmission components. The Top Notch toolholder system accepts this size 3 insert, making it a direct drop-in for shops already running compatible Kennametal Top Notch boring bars and external holders. Machinists and toolroom operators working in job shops, production machining, and maintenance environments will find this insert appropriate for both roughing and finishing passes on Stub Acme forms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC5025 carbide grade with PVD TiAlN coating for extended wear resistance\u003c\/li\u003e\n\u003cli\u003eNAS insert style, size 3, fits Top Notch series toolholders\u003c\/li\u003e\n\u003cli\u003eCuts Stub Acme thread form at 29-degree included angle\u003c\/li\u003e\n\u003cli\u003e5 TPI internal pitch, right-hand orientation\u003c\/li\u003e\n\u003cli\u003eHandles both internal and external threading operations\u003c\/li\u003e\n\u003cli\u003eMaterial grades C2 and C6 coverage for broad workpiece compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Kennametal Top Notch series toolholders accepting size 3 NAS-style threading inserts.
