A tough substrate with PVD coating and a special
84 SUMOTEC surface treatment. Suitable for machining
steel and stainless steel at low to medium cutting
speeds and moderate to high feeds. The grade
features high toughness and recommended for
interrupted cuts and machining under unstable
conditions. May be used on high temperature alloys at
low cutting speeds.
