TNMG 160408-PM 4325 standard carbide (coated) turning inserts with three cutting edges

T - triangular shape of turnining insert

N - Insert without clearance under main cutting edge (0°)

M - Tolerances and dimensions of carbide turning insert

G -Duble sided chipbreaker - with hole

16 - Length of cutting edge 16,5mm

03 - Height (thickness) of insert 4.76mm (from bottom of the insert to the top of the cutting edge)

08 - Nose radius R0.8

QP1025 - ISO Grade P20 - The type of carbide grade and the coating on inserts is originally intended for turning steel , steel alloys but it also performs when turning other alloys.

• Material: ISO grade carbide (tungsten):
  • For steel P10-30 (between wear resistance and shock resistance)(See ISO grade tables.)
  • CVD coating - thicker less precise layer coating
• Feed speed in mm/rev - 0.1-0.3
• Cut depth - 0.5mm - 3.0mm
• Cuting speed - 260 - 400m/min
• Turning insert feature:
  • Reliability and long endurance.
  • Recommended for all purposes and applications.

Tips and Tricks:

• For rough turning it is recommended  to use inserts with bigger nose radius (like R1.0), 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 R0.4), with that we reduce preasure on insert, increase cutting abilities, reduce vibration and we make better finishing surfaces.
