It features a micrograin carbide substrate with a PVD-applied titanium nitride (TiN) coating and carries the MXC manufacturer grade. The insert is right-hand orientation with a 29-degree included angle, a 3\/8-inch inscribed circle (0.3750 inches), and a thickness of 0.146 inches. This insert is used by machinists and CNC operators requiring precise, repeatable internal Stub Acme threads on a wide range of workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal threading operations across a broad material range, including ferrous, non-ferrous, stainless, heat-resistant alloys, and cast materials, as indicated by the universal primary workpiece material classification (H, K, M, N, P, S material codes). It is appropriate for both manual and CNC turning centers where Stub Acme thread profiles are required in production or job-shop environments. The laydown-style seating provides stable, repeatable positioning in compatible 16IR-style toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin substrate for wear resistance and edge stability\u003c\/li\u003e\n  \u003cli\u003ePVD TiN coating extends tool life across diverse workpiece materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand internal Stub Acme thread profile at 12 TPI with 29-degree included angle\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle (0.3750 inches) for precise toolholder fit\u003c\/li\u003e\n  \u003cli\u003eUniversal material compatibility covering codes H, K, M, N, P, and S\u003c\/li\u003e\n  \u003cli\u003eCE certified; manufactured under ISO 13485:2016, ISO 14001:2015, and ISO 45001 quality and environmental management systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 16IR-style internal threading toolholders.
