CNMG120408PMG CA125P (TMK00475)

The CNMG120408PMG CA125P is a high-performance indexable turning insert designed for medium to heavy general turning of steel and cast iron. The CA125P CVD-coated carbide grade provides excellent wear resistance and thermal stability, while the PMG chipbreaker delivers reliable chip control at medium feeds and depths of cut. The distinctive dual-layer coating is clearly visible in the image — a black PVD top layer over a gold CVD base — combining the wear resistance of CVD with the toughness enhancement of the PVD overcoat.

Key Features

• Insert shape: C (80° diamond) — 2 cutting edges per insert
• Size: 12mm x 04mm thickness x 08 nose radius (0.8mm)
• Chipbreaker: PMG — positive medium geometry for general steel turning with good chip breaking at medium feeds
• Grade: CA125P (CVD + PVD dual-coated carbide) — high wear resistance with enhanced edge toughness for continuous and mildly interrupted cuts
• ISO application: P15–P35
• Edges: 2 cutting edges

Applications

External and internal turning, facing, and boring of carbon steel, alloy steel, and cast iron at medium cutting speeds and feeds. The 0.8mm nose radius improves surface finish and insert strength at higher feeds. Compatible with CNMG-style toolholders. Available in packs of 10.
