FAQ

What ISO code corresponds to CNMG 432?

The verified V1 mapping is CNMG120408.

What are the CNMG 432 dimensions in V1?

The record lists 12.7 mm IC, 4.76 mm thickness, 0.8 mm nose radius, and an approximately 5.16 mm hole diameter.

Can I treat another CNMG 432 as the same performance?

No. Verify grade, chipbreaker, coating, workpiece material, machine condition, and cutting parameters separately.
