THREAD TURNING • Easy and fast setup
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.
VDI DIN69880 Characteristics
• 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
• Efficient coolant supply internally through the tool and externally through the flange
Multi-Connection JHP-MC Line for VDI Toolholders with a bottom fed
coolant system to ensure maximum coolant in the cutting area
