Coromant Capto®

What is Coromant Capto®?

Launched in 1990, Coromant Capto® revolutionized tool holding systems by offering a unique solution for turning, milling, and drilling. This system, standardized as ISO 26623, combines the advantages of the HSK and BIG PLUS® tool holding systems, eliminating the need for drawbars by utilizing a tapered, flange-supported polygon shape to create a strong pull force.

Advantages of the Coromant Capto® System

  • Robust Cross-Section and Segment Clamping: Coromant Capto® utilizes a robust cross-section and segment clamping, which provides significant clamping force, rigidity, torque transmission, and precision. This enhances tool performance and longevity in demanding machining processes.
  • Versatility: Designed for turning, milling, drilling, and threading, Coromant Capto® is a multi-purpose tool system. This enables tools to be used in multi-tasking machines, increasing production flexibility.
  • Most Popular Choice: Coromant Capto® has become the most popular spindle interface in multi-tasking machines, improving the radial accuracy and torque transmission capability for both stationary (turning) and rotating (milling, drilling, threading) tools.
  • Torsional and Bending Rigidity: Thanks to its unique design, Coromant Capto® provides excellent torsional and bending rigidity, ensuring tool precision and reliability even under heavy load conditions.

Coromant Capto Technical Features

  • Taper and Flange: The taper and flange combine the best features of the HSK and BIG PLUS® clamping systems, improving pull force and supporting tool accuracy and stability.
  • Polygon Shape: The flange-supported polygon shape ensures excellent mechanical locking without the need for drawbars, simplifying the mounting and removal process.
  • High Rigidity and Torque Transmission: The structure offers high rigidity and torque transmission capacity, which is especially important in large and demanding machining operations.
