Product Description
CNMG 160412 PM Carbide Insert for Steel Machining
The CNMG 160412 PM carbide insert is a widely used turning insert designed for medium machining (PM) of steel and alloy steel. With its double-sided 80° diamond shape and negative rake geometry, it offers excellent edge strength and process stability in both roughing and semi-finishing operations.
The PM chipbreaker is optimized for stable chip control across a wide cutting range, making it suitable for continuous and slightly interrupted cuts. It provides smooth chip evacuation while maintaining consistent surface quality.
Thanks to its ISO CNMG 160412 geometry, this insert is compatible with standard CNC turning toolholders and supports multiple cutting edges per insert, improving tool economy and reducing tooling cost per part.
