VNMG 160404-MM OS5835 Carbide Turning Insert

The VNMG 160404-MM OS5835 is a negative-rake carbide turning insert designed for precision finishing and semi-finishing applications on CNC and manual lathes. With its 35° rhombic geometry, it is ideal for profiling and machining areas with limited clearance. The 0.4 mm corner radius makes it highly suitable for applications where fine surface finishes and tight dimensional tolerances are required.

Manufactured in OS5835 grade, this insert uses a fine-grained carbide substrate with a PVD coating, offering strong versatility across multiple materials. It is particularly effective for machining steels, stainless steels, and general cast irons under medium cutting conditions. The MM chipbreaker ensures smooth chip evacuation, controlled cutting action, and improved surface quality, even in challenging materials.

The VNMG 160404-MM OS5835 fits common external turning holders, including MVJNR and SVJNR, designed for 35° rhombic inserts. It is widely used in general engineering, mold making, and automotive industries where consistent finishing quality and productivity are essential.
