VNMG Inserts
VNMG Inserts – Precision Carbide Inserts for Fine Turning
What Are VNMG Inserts?
VNMG inserts are 55° diamond-shaped, double-sided carbide inserts designed for high-precision turning, profiling, and finishing operations in CNC lathes. Their sharp nose geometry and negative rake angle make them ideal for achieving fine surface finishes, especially in applications with tight tolerances or complex contours.
VNMG stands for:
-
V – 55° Diamond shape (acute angle, ideal for profiling)
-
N – 0° relief angle (neutral rake)
-
M – Medium tolerance
-
G – Type of chipbreaker/clamping configuration
With 4 cutting tips per insert (2 per side), VNMG inserts are favored in industries like aerospace, automotive, and die manufacturing where finish quality is critical.

Frequently Asked Questions
VNMG inserts are primarily used for high-precision turning, profiling, and finishing in CNC lathes, especially in tight tolerance applications.
VNMG = V: 55° diamond shape, N: 0° relief angle, M: medium tolerance, G: chipbreaker/clamp configuration.
They can machine steel, stainless steel, aluminum, titanium, and other exotic alloys used in precision engineering.
Yes, VNMG inserts are ideal for finishing due to their acute angle and sharp cutting edge.
Each VNMG insert has 4 cutting edges (2 per side).
VNMG inserts are 55° and sharper, better for finishing; CNMG inserts are 80° and stronger, ideal for roughing.
Yes, their shape makes them excellent for both internal and external profiling and taper machining.
Yes, they are available with PVD and CVD coatings like TiN, TiAlN, and Al₂O₃ depending on material and application.
Common chipbreakers include MF, VP, PF for fine finishing, and MM for light roughing.
