Carmex 16IR14ACMEP30 Threading Insert 14 Tpi Acme Solid Carbide

Product Description

The CARMEX 16IR14ACMEP30 is a solid carbide laydown threading insert designed for cutting internal Acme threads. It operates at 14 threads per inch with a 29-degree included angle, making it suited for precision thread-form work on a variety of workpiece materials. The uncoated P30 carbide grade delivers consistent performance across general-purpose and universal material classifications. With a 3/8-inch inscribed circle and a thickness of 0.146 inches, this insert seats securely in compatible right-hand toolholders for lathe-based internal threading operations. Licensed machinists and CNC turning specialists are the primary users.

This insert is configured for right-hand internal Acme thread cutting, a common thread standard found in lead screws, linear actuators, vises, and other power-transmission components. The Acme profile is used wherever a square-thread-style form is required for load-bearing movement. The P30 grade and universal material code coverage make this insert applicable across steel, stainless, cast iron, non-ferrous, and high-temperature alloy workpieces, supporting both production and job-shop environments.
