ISO application area

Recommendations

• First-choice geometry is -CM
• If chip control needs to be further improved, use -TF
• First-choice grade is GC1125, the all-round grooving grade for all materials and general conditions. Its fine-grained carbide with thin PVD coating has proved its performance in all kinds of grooving applications

​	​	​
​First choice for all materials is the -CM geometry	​	​Good chip control and surface finish due to the wiper design

​The CoroCut V-rail interface gives exceptional stability. Rotational speed can be multiplied with maintained tolerances and surface quality.
