Sandvik Coromant 7080849 Turning Insert TNMG432-PM 4335

Product Description

The SANDVIK COROMANT 7080849 is a solid carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. It carries the TNMG432-PM 4335 designation and belongs to the T-Max P series. The insert features a 60-degree triangle shape with a neutral hand orientation and is coated via CVD with a multilayer TiCN, Al2O3, and TiN coating stack. The PM chip breaker geometry is engineered for steel turning applications. With a 0.5000 inch inscribed circle and a 0.0313 inch corner radius, this insert fits standard TNMG toolholders and delivers controlled chip evacuation across a range of steel grades.

This insert is intended for turning steel workpieces in production and job-shop environments. The P-grade application range and CVD coating make it a practical choice for continuous and mildly interrupted cuts on low-alloy and carbon steels. It is installed by machinists and CNC operators in both roughing and semi-finishing passes where chip control and edge life are priorities. The PM breaker geometry supports moderate feed rates and depths of cut typical in general steel turning. The ISO code for this insert is TNMG 22 04 08-PM 4335.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and thermal protection on steel
• 60-degree triangle insert shape with 6 cutting edges per insert, reducing per-edge tooling cost
• PM chip breaker geometry optimized for steel turning with controlled chip flow
• Neutral hand orientation for use in standard TNMG right- and left-hand toolholders
• 0.0313 inch corner radius for a balance of edge strength and surface finish capability
• Clamp and pin holding method compatible with standard T-Max P toolholder systems

Compatibility

Designed as an OEM-style replacement insert for TNMG-style toolholders in the T-Max P series. The ISO designation TNMG 22 04 08-PM 4335 governs cross-reference to compatible toolholder systems accepting TNMG 432 inserts with clamp and pin holding.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and clamp screw per the toolholder manufacturer specifications when securing the insert. Inspect the insert seat and clamp for wear or debris before seating a new insert to ensure proper contact and edge stability.
