QG7215 - ISO Grade M20 - The type of carbide grade and the coating on inserts is originally intended for turning stainless 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 in mm/rev - 0.1-0.45
• Cut depth - 0.5mm - 4.0mm
• Cuting speed - 180 - 330m/min
• Turning insert feature:
  • Strong cutting edges reliability in hard cuting conditions and endurance.
  • Geometry of WNMG turning insert is shaped for strong turning.
    
  • Six cutting edges (when used properly, you can use it six times)
  • Inserts have strongly supported cutting edge.
  • Recommended for different purposes and applications, especially in case when you need to change cutting edge often.

• Tips and Tricks:
  
  • For rough turning it is recommended  to use inserts with bigger nose radius (like R0.8 - R1.2), so wear, force and heat is distributed over larger surface - which makes inserts more durable.
    
  • For finishing it is recommended to use inserts with smaller nose radius (like R0.8 - R0.4), with that we reduce preasure on insert, increase cutting abilities, reduce vibration and we make better finishing surfaces.
