CoroTurn® Prime

Small entering angles

The small entering angle (KAPR) will create a thin and wide chip which spreads the load and heat away from the nose radius. This results in increased tool life or allows for increasing cutting data.

Entering and lead angles:

A-type KAPR = 30°, PSIR = 60°
B-type KAPR = 25°, PSIR = 65°

Efficient edge utilization

​CoroTurn® Prime inserts have three edges per corner. One edge each for longitudinal, facing and profiling thus distributing the wear over a longer edge and not just the insert tip. It also moves heat away from the cutting zone helping inserts last substantially longer.

Fast tool indexing

With two inserts in the holder, the new CoroTurn® Prime Twin-tool saves significant time when changing tools to increase machine utilization and productivity.
