The Carmex Drop Head Thread Turning Holder is a precision external threading tool designed for professional machinists. With a 125 mm overall length, right-hand orientation, and a 20x20 mm square shank, it offers reliable performance for production threading tasks and deep recesses.

  • Design: Drop head configuration optimized for external thread turning, delivering precise cutter alignment and easy access to the insert.
  • Handedness: Right-hand orientation for standard external threading on lathes.
  • Overall Length: 125 mm (OAL) to reach longer thread runs while maintaining rigidity.
  • Shank Size: 20 x 20 mm square shank for stable clamping in common toolposts and holders.
  • Insert Compatibility: Accepts 16ER inserts, a proven geometry for clean, consistent thread profiles.
  • Application: External thread turning on CNC or manual lathes, suitable for bolts, studs, and threaded components.

The holder’s drop-head design keeps the insert aligned with the workpiece, promoting accurate thread form and better surface finish. Robust construction and secure clamping minimize tool deflection during heavier cuts, while the 125 mm reach enables efficient threading in tighter setups. With quick insert access and standardized 16ER geometry, it supports efficient setup changes and steady production flow in demanding threading operations.
