VDI Static Tool Holders

The VDI turret disc is designed to accept either OD or ID tool holders in any of the tool stations. VDI tool holders provide an accurate and fast method of affixing tools to the turret disc.

  • The VDI Quick Change Tooling System offers a faster alternative.
  • Change-over time for VDI tool holders is less than fifteen (15) seconds making possible a complete turret retooling of 12 tool holders in less than three (3) minutes – compared to the conventional bolt-on tool holder system which requires approximately five (5) minutes per tool holder change-over, requiring sixty (60) minutes to complete a turret retooling of 12 tool holders.
  • The savings increase as set-ups increase.
  • The benefits of faster set-ups represent a realistic way to increase productivity.
