Silent Tools™ for turning

Overcome vibrations in internal turning

Reduce vibration with Silent Tools™ unique damping technology

Silent Tools™ is an anti-vibration technology that enables internal turning with long overhangs. Solutions are available to reach lengths of up to 14 times the bar diameter.

Productivity gains

By using Silent Tools ™, productivity gains of up to 50% for shorter boring bars and up to 400% for longer overhang lengths are possible.

CoroTurn® SL adapter interface

CoroTurn SL is a modular system with exchangeable cutting heads, allowing you to create a wide range of tool combinations from a small inventory of adaptors and cutting heads.

Silent Tools™ turning adaptors
– next-gen vibration elimination

With Silent Tools™ damped turning adaptors, vibrations are kept to a minimum, increasing safety and productivity. By minimizing disruptions during internal turning operations, Silent Tools™ turning adaptors will lower your cost per component for a more profitable and competitive business.

Thanks to a substantial upgrade of the damping mechanism, Silent Tools™ turning adaptors are more efficient than ever at countering vibration forces at long overhangs.​

  • The damper body used to require manual fine-tuning, but is now calibrated and assembled automatically by a machine​
  • This automation results in a highly precise and predictable frequency area, perfectly matched to the adaptor's intended overhang and application​
  • The upgraded Silent Tools™ damping mechanism brings about a significantly more consistent performance across different length-to-diameter ratios when compared to the previous generation of turning adaptors​
  • This improvement translates into increased machining repeatability, providing an even more reliable and precise product

49 of our Silent Tools™ cylindrical turning adaptors (Ø16–25 mm and Ø32–100 mm), 96 adaptors with Coromant Capto® coupling (C3, C4, C5, C6, C8 and C10), 6 HSK-T adaptors (Ø32–60 mm) have been updated with the new damping mechanism.
