Sandvik Coromant 5725005 CNMG434-MR 2035 Turning Insert

Product Description

The SANDVIK COROMANT 5725005 is a CNMG-style indexable turning insert in the T-Max P series, designed for external and internal turning operations on CNC lathes and turning centers. It features a diamond-shaped (80-degree included angle) carbide substrate with a PVD-applied TiAlN and TiN coating stack optimized for work on stainless steel and other ISO M-group materials. The insert carries a neutral hand orientation and an MR chip breaker geometry, which manages chip curl at moderate to heavy feeds. Four cutting edges are available per insert, making it a cost-effective choice for production turning shops.

This insert is suited for stainless steel turning in both general production and job-shop environments. The MR chip breaker is engineered for medium cutting conditions where chip control on tough, work-hardening materials is a priority. The CNMG 12 04 16-MR 2035 ISO designation confirms its sizing and grade for machinists specifying inserts by ISO code. Typical applications include shaft work, flange facing, and contour turning where a 0.0630-inch corner radius and a maximum depth of cut of 0.4449 inches are appropriate.

Key Features

• PVD-coated TiAlN and TiN coating for extended tool life on stainless steel (ISO M) workpieces
• 80-degree diamond insert shape (CNMG) delivers a strong cutting edge with moderate clearance
• MR chip breaker geometry for reliable chip control at medium feeds and depths
• Four usable cutting edges per insert reduces per-edge tooling cost
• Clamp and pin holding method compatible with standard CNMG toolholders
• Maximum depth of cut 0.4449 inches (11.30 mm) supports both roughing and medium finishing passes

Compatibility

Designed as a direct-fit replacement for CNMG 12 04 16-MR 2035 inserts in standard CNMG-style toolholders that use clamp and pin insert retention. Confirmed ISO code: CNMG 12 04 16-MR 2035. Consult the T-Max P toolholder selection guide to confirm pocket and clamp compatibility before installation.

Installation Notes

Indexable turning inserts must be installed by a qualified machinist or toolroom technician following the toolholder manufacturer's torque and clamping procedure. Power down and lock out the machine spindle before indexing or replacing inserts. Inspect the insert pocket seat and clamping components for wear or debris before seating a new insert; a contaminated seat will cause premature edge failure. Do not exceed the maximum depth of cut or feed rate recommendations published in the T-Max P application guide for the 2035 grade.
