Frequently asked questions
Why use VNMG instead of DNMG?
VNMG has a 35° point (vs DNMG 55°) — the sharpest standard turning insert. Used for steep back-profile angles, deep grooves along shaft faces, and narrow-shoulder finishing where DNMG cannot reach. Downside: very fragile point, low feed, finishing only.
Common VNMG sizes?
VNMG160404 (general finishing, 20-25 mm shank) is the most common. VNMG160408 for slightly heavier finish cuts. 0.4 mm nose is the normal finishing choice; 0.8 mm is used for profiles with some roughing combined.
What toolholder matches a VNMG?
MVJNR (95° lead, right-hand) and MVVNN (negative vertical clamp, special profiles). Lead angle matters because VNMG profiles into tight corners — the wrong angle bumps the holder body against the workpiece.
Can I use a VNMG for general turning?
Not recommended. The 35° point is made for profile access, not general stock removal. Using a VNMG for general shaft turning wastes the insert (low feed, low depth of cut) and it chips faster than DNMG or CNMG would.
Best feed rate for VNMG finishing?
0.05-0.10 mm/rev for a 0.4 mm nose VNMG, at 180-240 m/min on steel. Below 0.05 mm/rev the insert rubs without cutting; above 0.10 the thin point overloads and chips.
