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.
