Description

Carmex Thread Turning Holder Top Clamp is a precision tool designed for internal threading tasks, engineered to perform reliably in both right-hand and left-hand applications. Its robust top-clamp design delivers stable, accurate thread cutting across demanding machining setups.

  • Top Clamp Design: Enhanced rigidity and stability during machining to reduce deflection and improve thread consistency.
  • Internal Threading Compatibility: Suitable for internal threading operations in both right- and left-hand directions for versatile use.
  • Insert Compatibility: Accepts IR and IL inserts, with secure engagement for precise, repeatable cuts (includes 16IR insert compatibility).
  • Dimensions: 200 mm overall length (OAL) with a 25 mm shank size, providing reach and stiffness in tight or awkward setups.
  • Durable Construction: Built to withstand high-speed machining and demanding materials, delivering long tool life and dependable performance.

This holder is ideal for shops and manufacturers that routinely machine internal threads in bores, housings, or components where precision fit and surface finish matter. The combination of top-clamp rigidity, insert versatility (IR/IL), and balanced geometry helps reduce chatter, improve roundness, and produce consistent thread profiles across runs, contributing to better part quality and reduced rework.
