The Dieterle tool line, offered by the CIMtek Group, includes the Eco-Star External Tooling System, consisting of hardened and tempered toolholders with the Eco-Star location system for ease of insert change and precise insert location. The design features a pressed steel bushing and allows for changing the insert without removing the toolholder from the machine. The ground, high-quality carbide inserts are suitable for a wide range of applications. The system enables turning, grooving, parting-off, threading, and copying with only one toolholder when used in a Swiss CNC lathe or sliding headstock machine. Carbide grades with special coatings are provided for use with materials including high-alloy steels, titanium, and stainless steels.
