GC4325 is a new generation coated cemented carbide grade for steel turning.
The new tool material provides higher potential for increasing cutting speeds and a longer, more predictable tool life with high reliability over an extended broad ISO P25 application area, claims Sandvik Coromant. The insert substrate and coating are designed to better withstand high temperatures, reducing the effect that causes excessive wear. The grade is capable of maintaining the insert edge line at higher temperatures, which means the capability of higher cutting speeds. Sandvik Coromant estimates an average productivity increase of 30 per cent.
