What distinguishes CNGA
Base configuration
Cylindrical fixing hole; no chipbreaker in the base type.
Tolerance symbol G identifies a class. Use the applicable product drawing for acceptance limits.
Choose the comparison that matches your question
This family contains 3 size/thickness groups: 1204, 1606, 1906. Compare radii within one group first; moving between groups can change the insert-seat envelope.
Shape and clearance do not identify workpiece material, coating, grade or cutting data. Use an exact catalogue example when available; otherwise confirm a maker’s full designation before ordering.

Shape, clearance, configuration and nominal code tables only. No grade, usable-edge count, catalogue availability or acceptance tolerances inferred. Values labeled “code table” are interpretations of a designation, not measurements of a delivered product. Product-row values are reported separately, including differences in printed precision.
