Eight-Edge Inserts

The Eight-Edged Inserts of CoroTurn 300 ensure good heat transformation for predictable performance and wear. More edges also means fewer inserts which in turn means better control of the inventory. The geometries are designed for excellent chip breaking within their respective application areas. The eight-edged insert design means less carbide per edge which means less material to recycle and waste.

Chip Control and Long, Predictable Tool Life

High precision coolant from above controls the chip breaking for secure machining, while under coolant controls the temperature for long and predictable tool life. The coolant also has positive effects on surface quality.

High-Quality Surfaces

To achieve the highest quality of surfaces, the key is to prevent cutting forces from causing micro-movements of the insert. iLock™, an interface between insert and holder, was developed to bridge this challenge.
