Description

Carmex Thread Turning Holder with Internal Coolant is a precision tool designed for high-speed external threading, offering direct coolant delivery to the cutting edge for cleaner threads and improved uptime. Built for right-hand operations, it features a robust 150 mm overall length and a compact 25x25 mm shank to fit into standard CNC setups with stable, repeatable performance.

  • Internal coolant delivery: integrated coolant channel directs coolant to the insert to reduce heat, improve chip control, and extend insert life.
  • Right-hand external threading orientation: specifically configured for reliable, consistent external thread turning.
  • 150 mm overall length: extended reach to access deeper threads and long chamfers without compromising rigidity.
  • 25 x 25 mm shank: square shank size provides secure mounting and alignment in compatible holders.
  • 16ER insert compatibility: designed to accept standard 16ER form inserts for versatile threading applications.
  • Stable seating and alignment: engineered interface ensures precise insert positioning during demanding cuts.
  • Chip control performance: thoughtful geometry and coolant flow work together to minimize chip buildup and improve surface finish.

This holder streamlines threading operations by marrying internal coolant with precise geometry, delivering consistent thread quality at higher feeds while reducing heat-related wear. The combination of internal cooling, extended reach, and a squared 25x25 shank makes it a reliable choice for deep external threads in production environments, helping you maintain accuracy and efficiency across long runs.
