CNMG090408 AH6225 Tungaloy indexable turning insert — PVD-coated carbide, 80° rhombic

The CNMG090408 AH6225 is an ISO-standard turning insert designed for external and internal turning, optimised for medium machining of stainless steels and mixed production conditions.

• PVD-coated carbide grade AH6225
• Optimised for stainless steels
• 80° rhombic geometry, 0° relief
• Double-sided chipbreaker, with hole

Consistent cutting performance for stainless steels

The insert delivers stable cutting thanks to its PVD-coated carbide composition and the AH6225 grade, which is designed for a sharp yet robust cutting edge. In practice, this means consistent surface quality and predictable tool life under variable batch conditions. The rhombic 80° geometry supports both axial and radial engagement, while the 0° relief reduces vibration in steady turning operations. The result is a dependable solution for shops that require repeatable results on stainless steels, with clear process advantages over uncoated alternatives.

Secure tool clamping and straightforward tool matching

Compatibility with holders depends on form, relief angle, tolerance class, fastening, size and thickness; the insert’s cylindrical hole and standard ISO dimensions simplify selection of the correct toolholder and clamping kit. The double-sided configuration permits economical indexing, and the central hole enables positive location and secure fixation. For production lines that must change inserts quickly, this design reduces downtime and ensures reproducible positioning, which supports high process reliability and fewer setup deviations.

Versatile grade for mixed production and improved chip control

The universal AH6225 grade is balanced for medium cutting conditions and varying materials, providing an advantageous mix of wear resistance and edge toughness. The integrated chipbreaker promotes controlled chip formation across different feeds and depths of cut, lowering the risk of chip entanglement and improving surface finish. For operations that alternate between small-batch prototypes and serial runs, the insert offers a pragmatic compromise between economy and performance, extending effective machining windows before regrinding or replacement is needed.
