Sumitomo 194AANZ CNMG431ESU Cermet Turning Insert

Product Description

The SUMITOMO 194AANZ is a CNMG-style cermet turning insert designed for precision metal cutting in CNC lathe and turning center applications. It features an 80-degree diamond insert shape with a neutral hand orientation, a 1/2 inch inscribed circle, and a 1/64 inch corner radius. The T1500Z cermet grade substrate is applied with a PVD coating process, making it well suited for finishing and semi-finishing passes on steel workpieces. Licensed machinists and CNC operators use this insert for achieving tight tolerances and consistent surface finishes at moderate to high cutting speeds.

This insert is intended for turning operations on steel and similar ferrous materials in both production shop and job shop environments. The ESU chip breaker geometry supports controlled chip evacuation during continuous cuts. The CNMG form factor with a negative rake angle and clamp-plus-pin holding method is compatible with standard CNMG toolholders found in most commercial turning setups. The ISO designation for this insert is CNMG120404N-SU, and the ANSI code is CNMG431ESU, which are commonly referenced for cross-matching toolholder compatibility.

Key Features

• Cermet insert material with PVD coating for wear resistance on steel workpieces
• 80-degree diamond insert shape (shape code C) for versatile turning profiles
• ESU chip breaker geometry promotes consistent chip control during finishing cuts
• Negative rake angle with N clearance code and M tolerance code per ANSI and ISO 13399 standards
• Clamp and pin holding method provides secure seating in compatible CNMG toolholders
• 1/64 inch corner radius supports fine surface finish requirements

Compatibility

Designed as a direct-fit replacement for standard CNMG431 toolholder pockets. Cross-reference by ANSI code CNMG431ESU or ISO code CNMG120404N-SU when matching to existing toolholder inventory.

Installation Notes

Installation and indexing should be performed by a qualified machinist or CNC tooling technician with the machine in a fully stopped and locked-out state. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer when seating the insert. Inspect the toolholder pocket for chips, wear, or damage before seating a new insert. Do not exceed the toolholder manufacturer's recommended cutting parameters for this insert style and grade.
