The toolholder allows external cooling (via adjustable and pluggable coolant nozzles) and internal cooling.
The toolholder is reversible. This means that the tool can be mounted facing the left spindle or the right spindle.
The tool holder is supplied with 1 plug so inner coolant can be used when only 1 tool is mounted. Due to the distribution of the internal coolant channels, it is possible to have internal coolant available if 2 tools are mounted.
