Designation basics

How Turning Insert Codes Work

Use a designation as a structured starting point. Depending on the standard and family, it can identify attributes such as shape, clearance, tolerance, type, size, thickness, and nose radius.

Confirm the relevant manufacturer or standard documentation before treating any code characters as a complete specification.

ANSI / ISO

Reference formats

ANSI and ISO designations can present a base insert size differently. The current verified V1 example is CNMG 432 / CNMG120408.

I know my machining application

Use the family pages to identify a starting point, then validate geometry, grade, chipbreaker, workpiece material, and machine conditions with manufacturer documentation.

FAQ

Which turning insert family should I open first?

Start with the code family visible on your current insert or holder documentation.

Can this page select a grade for my material?

No. V1 does not provide a grade or chipbreaker recommendation engine.

What should I compare before switching suppliers?

Confirm the insert code and dimensions, then separately validate grade, chipbreaker, coating, workpiece material, and machining conditions.
