QG7215 - ISO Grade P20 - The type of carbide grade and the coating on inserts is originally intended for turning steel, but it also performs when turning other alloys.

• Material: ISO grade carbide (tungsten):
  • For stainless steel M20 (between wear resistance and shock resistance) (See ISO grade tables.) 
  • PVD coating - thinner more precise layer coating
• Feed speed mm/rev - 0.15-0.45
• Cut depth - 0.1mm - 2.0mm
• Cuting speed - 180 - 330m/min
• Turning insert feature:
  • Strong cutting edges best reliability in hard cuting conditions and long endurance.
  • Geometry of CCMT turning insert is shaped for medium strong turning.
  • Inserts have secured and strongly supported cutting edge.
  • Recommended for different purposes and applications.
