Tools with Bottom Fed High Pressure Coolant Systems 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 THREAD TURNING
serves mainly stationary turning tools.

VDI DIN69880 Characteristics
• 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.
• Efficient coolant supply internally through the
tool and externally through the flange.
Note: the shank lengths of the tools with bottom fed high
pressure coolant systems are shorter than the lengths of Multi-connection JHP-MC line for VDI toolholders
equivalent standard tools - adjusted to the VDI Toolholders. with a bottom fed coolant system ensures
maximum coolant in the cutting area.
Tools with bottom fed high pressure coolant systems
belong to the Multi-Connection JHP-MC line and are Basic Dimensions of Threading Tools with a
suitable for mounting on VDI DIN69880 Toolholders. Bottom Fed High Pressure Coolant System

The tools include a bottom coolant inlet hole and the CDX — insert overhang
VDI JHP-MC Toolholders feature a long coolant outlet
slot that enables adjustment of the tool’s overhang.
Main Advantages
Max. tool overhang Min. tool overhang
• Reduces cutting time.
• Provides longer tool life of cutting edge.
• Very effective cooling down of the cutting edge,
reducing sensitivity to heat fluctuations.
• Enables better chip evacuation.
