CoroTurn® Prime

All-directional turning

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.

No chip jamming

​PrimeTurning™ method enables turning away from the shoulder thus eliminating the possibility of chip jamming as commonly observed in conventional turning. This results in an excellent surface finish and avoids tool damage.
