Description

Carmex Thread Turning Holder Top Clamp External (Right-Hand) is a precision external threading solution designed for reliable, repeatable results on standard lathes. Built for shops that demand both versatility and stability, it pairs a compact 100 mm body with a robust top-clamp design and ER-compatible inserts to handle a wide range of external thread turning tasks.

  • Right-Hand External Thread Turning Holder: optimized for external threading operations with the threading direction aligned to right-hand cuts.
  • 100 mm Overall Length (OAL): compact, rigid body designed for clean tool engagement and consistent depth control.
  • 12 x 12 mm Shank Size: standardized shank footprint for secure seating in common tool holders and turret stations.
  • Top Clamp Clamping Option: secure, stable clamping that minimizes deflection and maintains precise thread form during cutting.
  • 1.5° Helix Angle: engineered angle promotes efficient chip evacuation and smooth cutting action, reducing built-up edge and chatter.
  • 16ER Insert Readiness with ER/EL Compatibility: designed for use with ER-style inserts (and EL variants), offering broad compatibility for various external threading applications.

This holder delivers predictable performance in external thread turning by combining a rigid top-clamp approach with a thoughtful helix geometry. The dual clamping capability (top clamp plus traditional screw options) provides setup flexibility to match material, depth of cut, and threading length. It's an excellent choice for production environments that require consistent thread quality on shafts and fasteners, with the confidence of a proven Carmex design.
