Sandvik Coromant 5724718 Ceramic Turning Insert CNGA431S0625

Product Description

The SANDVIK COROMANT 5724718 is a ceramic turning insert designed for high-performance metal cutting in demanding machining environments. Carrying the CNGA431S0625 designation within the T-Max P series, this insert features a titanium nitride (TiN) coating applied via PVD process, which improves surface hardness and wear resistance. It has an 80-degree diamond shape, a neutral hand orientation, and a corner radius of 0.0156 inches (1/64 inch). The inscribed circle measures 0.500 inches in diameter. With four available cutting edges, this insert is suited for hard material turning applications where ceramic tooling is preferred over carbide for extended tool life at elevated cutting temperatures.

This insert is intended for turning operations on hard workpiece materials, coded H per ISO designation CNGA 12 04 04S01525 6050. It fits into CNGA-style insert pockets and is held in place using a clamp and pin method. Typical applications include finish and semi-finish turning on hardened steels and other hard materials in both production shop and job shop settings. It is installed and used by machinists and CNC operators on lathes and turning centers equipped with compatible toolholders.

Key Features

• Ceramic insert with PVD titanium nitride (TiN) coating for wear resistance in hard material turning
• 80-degree diamond insert shape (Shape Code C) for versatile approach angles
• Neutral hand orientation compatible with both left- and right-hand toolholders
• Four cutting edges per insert for extended tool economy
• Chip breaker style A with clamp and pin holding method for secure, repeatable seating
• T-Max P series with ISO code CNGA 12 04 04S01525 6050 for precise toolholder matching

Compatibility

Designed to seat in CNGA-style insert pockets within the T-Max P series toolholder system. Confirm toolholder designation accepts CNGA 431 geometry and clamp-and-pin holding before installation.

Installation Notes

Insert replacement should be performed with the machine fully powered down and the spindle locked. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer when securing the clamp and pin. Inspect the insert pocket and seating surface for chips or debris before seating a new insert. Ceramic inserts are brittle compared to carbide - avoid impact loads and interrupted cuts unless the grade is specifically rated for that application.
