Carmex Top Clamp Thread Turning Holder for Internal threading is a versatile, precision-focused tool designed for machinists who need durable, accurate internal threading capabilities. Built for both right- and left-hand threading tasks, it delivers stable performance across demanding high-speed operations.

• Top Clamp Design: Provides enhanced rigidity and stability to minimize deflection during cutting for cleaner, more consistent threads.
• Handedness: Suitable for both right-hand and left-hand internal threading applications, reducing the need for multiple holders.
• Insert Compatibility: Accepts IR and IL inserts, including 16IR, for flexible threading geometries without changing tools.
• Dimensions: 170 mm overall length (OAL) with a 20 mm shank, designed to fit standard machine tool changers and setups.
• Durability: Robust construction engineered to withstand high-speed machining and demanding production environments.

By delivering a secure interface and rigid support, this holder consistently produces accurate thread profiles and smooth finishes, even in tough materials. The ability to swap inserts without replacing the entire holder reduces downtime and keeps production flowing. Its rugged build handles high RPMs and heavy workloads, making it a reliable choice for precision threading in manufacturing, automotive, and aerospace contexts.
