Insert TNMM 160308 P25

TNMM 160308 turning inserts in grade P25 are cutting tools designed for metal machining, ideal for turning steel and similar materials. Grade P25 is one of the classic choices for general steel machining, combining good wear resistance and hardness.

Grade P25:

Category: Grade P25 belongs to the ISO P category, specifically designed for steel machining.

Base Material:

Cemented Carbide: Provides strength and durability against cutting forces.

Coating: Typically includes multi-layer CVD (Chemical Vapor Deposition) or PVD (Physical Vapor Deposition) coatings.

Types of Machining:

Suitable for semi-finishing and finishing operations.

Designed for moderate speeds and medium feed conditions.

Recommended Cutting Parameters:

Cutting Speed (Vc): 200–400 m/min, depending on the type of steel and the tool's condition.

Feed Rate (f): 0.1–0.3 mm/rev for semi-finishing and finishing.

Depth of Cut (ap): 1–4 mm, depending on the application.
