Manufactured from solid carbide in an uncoated P30 grade (material grade C5), it delivers consistent thread form on a wide range of workpiece materials. The insert features a 29-degree included angle that matches the Stub Acme thread standard. With an inscribed circle of 0.375 inches and a thickness of 0.146 inches, the 16 ER insert style seats securely in compatible laydown toolholders. Machinists and CNC operators use this insert for precision threading on lathes and turning centers where Stub Acme thread profiles are required.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external Stub Acme threading operations in production and job-shop turning environments. Its universal primary workpiece material rating covers a broad range of materials including carbon steels, stainless steels, cast irons, non-ferrous metals, high-temperature alloys, and hardened materials, as indicated by material codes H, K, M, N, P, and S. It is installed in right-hand laydown threading toolholders that accept the 16 ER insert style. Typical applications include lead screws, power transmission components, and mechanical actuator threads requiring the Stub Acme form.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStub Acme external thread form at 8 TPI with a 29-degree included angle\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction in uncoated P30 grade for consistent cutting performance\u003c\/li\u003e\n  \u003cli\u003eUniversal material compatibility covering carbon steel, stainless, cast iron, non-ferrous, and high-temp alloys\u003c\/li\u003e\n  \u003cli\u003e16 ER insert style with 0.375-inch inscribed circle for secure laydown toolholder seating\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut orientation for standard external threading operations\u003c\/li\u003e\n  \u003cli\u003eManufactured to CE, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in laydown threading toolholders that accept the 16 ER insert style.
