SANDVIK Coromant has introduced the GC1030 and GC4240, the first in a new line of milling grades to give productivity a boost through improved performance in the demanding steel milling operations.
These two insert grades have been especially optimised for shoulder milling but give a reliable and secure performance in other tough milling operations as well.
GC1030 is the perfect choice when machining difficult materials or in unstable conditions, for example, long overhangs with vibration problems. The improved wear resistance provided by the unique PVD coating makes it a versatile and reliable insert grade. It is suitable for use in smaller cutters or when endmilling.
GC4240 is a grade with completely new substrate and CVD coating, offering higher security for trouble free machining. It is a versatile grade that can be adapted to various milling operations, however, according to Sandvik Coromant this grade should be the first choice for shoulder milling and tougher operations in steel milling and where high metal removal rate is important.
