The ISO designation system for toolholders for turning applications
For turning toolholders, as for indexable inserts, there is a similar ISO designation system.
The system is designed so that each important feature and dimension of the toolholder is shown using a code system. This becomes the name of the toolholder.
This system has several advantages:
- Unique naming of a toolholder (supplier independent)
- All important features and dimensions are clearly stated in the name
- Some code positions relate to the insert that can be used in the toolholder
It's important to remember that the ISO designation system is not a system that standardizes the quality of the toolholders.
