Sandvik Coromant 5753816 Turning Insert TNMG331-MF 1125

Product Description

The SANDVIK COROMANT 5753816 is a TNMG-style triangular turning insert in the T-Max P series, designed for general turning operations on CNC lathes and turning centers. Manufactured from solid carbide with a TiAlN and AlCr2O3 PVD coating, it delivers wear resistance and thermal stability in demanding cutting environments. The insert features a neutral hand orientation, an MF chip breaker geometry optimized for finishing passes, a 3/8-inch inscribed circle, and a 1/64-inch corner radius. It provides 6 cutting edges per insert, making it an efficient choice for production turning environments where tool economy matters.

This insert is primarily targeted at machinists and tooling technicians working in stainless steel (ISO material code M) applications, with secondary suitability for superalloys and titanium (ISO material code S). It is well suited for light to medium finishing cuts where controlled chip formation and surface finish are priorities. The ISO designation for this insert is TNMG 16 04 04-MF 1125, and it is compatible with standard TNMG toolholders using clamp or pin holding methods. It is applicable in both job shop and production environments where stainless and high-temp alloy turning is routine.

Key Features

• TiAlN and AlCr2O3 PVD coating for heat resistance and extended tool life in stainless steel and superalloy cutting
• MF chip breaker geometry engineered for controlled chip formation during finishing operations
• 6 available cutting edges per insert for reduced tooling cost per edge
• Neutral insert hand — compatible with right-hand and left-hand toolholder setups
• Clamp and pin holding method for secure seating in TNMG-compatible holders
• Grade 1125 carbide substrate balances toughness and wear resistance for difficult-to-machine materials

Compatibility

Designed for use in standard TNMG-style toolholders that accept clamp or pin clamping methods. ISO designation TNMG 16 04 04-MF 1125 confirms fitment in holders dimensioned for this insert class. Primary workpiece material compatibility is stainless steel, with secondary compatibility for superalloys and titanium.

Installation Notes

Insert seating and indexing should be performed with the machine fully powered down and at a complete stop. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer — do not overtighten or use improvised tooling to secure the insert. Inspect the insert pocket for debris or wear before seating a new insert, as a damaged pocket will cause premature insert failure. This insert is intended for installation and use by qualified machinists or tooling technicians familiar with CNC turning operations.
