T: Triangular geometry featuring a 60° corner angle that yields superb profiling and shoulder clearance.
N: Negative rake clearance angle (0°), reinforcing the cross-sectional mass to provide 6 distinct cutting edges per insert (3 top, 3 bottom).
M: Medium manufacturing tolerance class configuration.
G: Features a central countersunk cylinder hole for rigid top-clamp and pin locking mechanisms.
16: Nominal cutting edge length measuring 16.5 mm.
04: Robust insert body thickness measuring 4.76 mm.
04: A sharp 0.4 mm nose radius, which is perfect for delivering micro-finish surface textures and tight contour dimensions.
