20B - ISO Grade M20  The type of carbide grade and the coating on inserts is originally intended for turning stainless steel , steel alloys but it also performs when turning other alloys.

• Material: ISO grade carbide (tungsten):
  • For stainless steel M 20 (between wear resistance and shock resistance)(See ISO grade tables.)
    
  • CVD coating - thicker rough layer coating
• Feed speed in mm/rev - 0.1-0.25
• Cut depth - 0.5mm - 3.0mm
• Cuting speed - 140 - 220m/min
• Turning insert feature:
  • Strong cutting edges best reliability
    
  • Geometry of DNMG turning insert is shaped so, that many times this inserts are used in cases that other inserts like DCGT are to weak for the job.
  • Four cutting edges (when used properly, you can use it four times)
  • Recommended for all purposes and applications special in roughing
