CNMG 160608-OPM OS2325S Carbide Turning Insert

The CNMG 160608-OPM OS2325S is a negative-style carbide turning insert designed for semi-finishing and finishing operations. With its 80° diamond shape (C-type) and double-sided geometry, it provides two cutting edges per side for cost efficiency and durability.

Manufactured in OS2325S grade, this insert features a CVD-coated carbide substrate optimized for wear resistance and toughness. It is suitable for machining steels and stainless steels, performing reliably in continuous and light interrupted cuts. The OPM chipbreaker ensures smooth chip control at medium to low feed rates, reducing heat and improving surface quality.

The 160608 designation means the insert has a 16 mm inscribed circle, 6.35 mm thickness, and an 8 mm cutting edge length, making it suitable for medium turning operations. Commonly used in automotive, machinery, and general engineering, this insert offers a balance of tool life, cutting efficiency, and surface precision.
