GC4225 from Sandvik Coromant represents the next generation of P25 grades for general steel turning. With general steel turning, the steel material varies from un-alloyed to high-alloyed bar material to various forgings and castings. The type of operation also varies from rough to finish turning with conditions ranging from good to difficult.

The insert has an improved capacity to adapt to variations in workpiece material and operational demands towards the tougher end of applications, thus providing more versatility. The new black and yellow grade provides a potential for increasing productivity through higher cutting data, backed up by improved reliability, the company says.

Added tool life predictability makes GC4225 easier to apply with higher security. The grade is said to be more durable, partly through an increased ability to withstand thermal demands. It has proven to be even more suitable for various optimization requirements for general steel turning, the company says.
