THREAD TURNING VDI DIN69880 Characteristics

Tools with Bottom Fed High Pressure Coolant Systems Suitable for External Threading

VDI DIN69880 is the most popular quick change
adaptation system for CNC turning machines with
disc-type turrets. This standard holder adaptation
serves mainly stationary turning tools.

• Easy and fast setup.
• High stiffness, thanks to straight shank
and flange face contact.
• Rigid design due to a serrated clamping system.
• High accuracy and center height repeatability.
• Compact and light design.
Note: the shank lengths of the tools with bottom fed high • Efficient coolant supply internally through the
pressure coolant systems are shorter than the lengths of tool and externally through the flange.
