The Carmex Top Clamp External Thread Turning Holder (Left-Hand) is a precise, versatile tool designed for external thread machining on lathes. Built for left-handed threading, it pairs with 16EL inserts for reliable, repeatable performance in a variety of threading applications.

  • Left-Hand external thread turning holder: specifically configured for left-handed threading operations on external workpieces, delivering consistent thread starts and controlled cutting action.
  • Top clamp and screw clamp options: flexible clamping methods allow you to choose the most stable setup for your job, with the top clamp design offering secure, rigid retention during cutting.
  • 100 mm Overall Length (OAL): provides adequate reach and rigidity for dependable performance on longer machining setups.
  • 12 x 12 mm shank: compact, compatible shank size that fits standard tool posts and holders for reliable integration into existing tooling setups.
  • 16EL insert compatibility: engineered to work with 16EL inserts, enabling precise thread geometry and consistent chip formation.
  • 1.5° helix angle: optimized helix angle promotes efficient chip evacuation and smooth cutting progression during threading operations.
  • ER/EL insert compatibility: designed to accommodate ER and EL inserts, expanding your threading options across a range of materials and thread specs.

This holder delivers a secure, stable interface for external thread turning, helping you achieve accurate thread forms with minimal deflection. The combination of flexible clamping, a thoughtful helix angle, and insert versatility makes it a reliable choice for left-hand threading tasks on manual or CNC lathes, improving surface finish and tool life in demanding threading work.
