Manufactured to a VKX grade with a PVD-applied TiN coating, it is built for right-hand external threading operations across a wide range of workpiece materials. The insert features a 45-degree included angle and measures 0.375 inches inscribed circle (9.53 mm) with a thickness of approximately 0.142 inches (3.60 mm). Machinists and CNC turning specialists use this insert in production and job-shop environments where precise Buttress thread profiles are required.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external Buttress thread turning on lathes and CNC turning centers. The American Buttress thread form it produces conforms to ANSI B1.9-1973, making it appropriate for applications such as hydraulic cylinders, breech mechanisms, and load-bearing threaded components where one flank carries the primary thrust load. It is compatible with universal workpiece material groups including ferrous, stainless, cast iron, non-ferrous, and heat-resistant alloys, corresponding to material codes H, K, M, N, P, and S.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with PVD TiN coating for wear resistance across diverse workpiece materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand external American Buttress thread form, 12 TPI, conforming to ANSI B1.9-1973\u003c\/li\u003e\n  \u003cli\u003e45-degree included angle with a single tooth per side for clean, defined thread flanks\u003c\/li\u003e\n  \u003cli\u003eInsert style 3ER with size code 3 for compatibility with standard 3ER toolholders\u003c\/li\u003e\n  \u003cli\u003eInscribed circle of 3\/8 inch (9.53 mm) and thickness of 3.60 mm for precise seating in holder pockets\u003c\/li\u003e\n  \u003cli\u003eUniversal material grade VKX suitable for steel, stainless, cast iron, non-ferrous, and superalloys\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3ER-style threading toolholders.
