Sandvik Coromant 5754195 Turning Insert TNMG432-MM 1125

Product Description

The SANDVIK COROMANT 5754195 is a TNMG432-MM 1125 series turning insert designed for external and internal turning operations on CNC lathes and turning centers. This solid carbide insert features a dual-layer TiAlN and AlCr2O3 coating applied via PVD process, delivering strong wear resistance and thermal stability across a range of workpiece materials. The triangular insert geometry provides 6 cutting edges per insert, maximizing tool life per piece. With a 0.8345-inch insert length, a 0.5-inch inscribed circle, and a 1/32-inch corner radius, this insert suits moderate to finishing passes. The MM chip breaker geometry promotes controlled chip evacuation in steel and multi-material turning applications.

This insert is suited for production turning on steel as its primary workpiece material. Secondary material compatibility includes stainless steel, non-ferrous metals, superalloys, and titanium, making it versatile across job shop and production environments. It belongs to SANDVIK COROMANT T-Max P series, a platform used widely in ISO P and ISO M turning applications. The neutral hand orientation and standard TNMG geometry allow fitment in a broad range of qualified toolholders. Typical users are CNC machinists, tool-and-die shops, and production turning operations requiring consistent chip control and insert-to-insert repeatability.

Key Features

• TiAlN and AlCr2O3 dual-layer PVD coating for extended wear life in steel and stainless turning
• MM chip breaker geometry promotes reliable chip control across a range of feed rates and depths
• 6 usable cutting edges per insert reduces tooling cost per edge
• Neutral hand orientation compatible with standard TNMG toolholders
• 60-degree triangular insert shape with N clearance angle and M tolerance code
• Clamp and pin insert holding method supports secure, repeatable seating

Compatibility

Designed for use in TNMG-style toolholders accepting a 432 insert size with clamp and pin holding method. Compatible with T-Max P series tooling systems. ISO designation TNMG 22 04 08-MM 1125. Verify toolholder pocket dimensions and clamping style before installation.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Power down and lock out the machine before changing inserts. Inspect the toolholder pocket and seating surfaces for chips or debris before seating the new insert, as contamination causes premature edge failure. Follow the toolholder manufacturer torque guidelines for the clamping screw and do not exceed the recommended depth of cut for the selected chip breaker geometry.
