Turning inserts and grades for stainless steel

Choosing the right insert grades for stainless steel turning is crucial, as these operations typically yield more friction and heat than many other materials. Find the best insert grade here to ensure good chip control and long and reliable tool life.

GC2025

F​rom semi-finishing to roughing, this CVD-coated grade is the first-choice grade when turning stainless steel. With good resistance to thermal and mechanical shock, it provides excellent edge line security for interrupted and continuous cuts.

Benefits and f​eatures​

  • High edge line security
  • Resistance to thermal and mechanical shock
  • Predictability and security
