What distinguishes SNMG

Base configuration

Cylindrical fixing hole; chipbreakers on both faces in the base type.

Tolerance symbol M identifies a class. Use the applicable product drawing for acceptance limits.

These families share the outline letter S. Differences in clearance, tolerance and mounting remain relevant even when IC matches.

Choose the comparison that matches your question

This family contains 5 size/thickness groups: 09T3, 1204, 1506, 1906, 2507. 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.
