CNMG 120416 AH6225 – Turning indexable insert by Tungaloy

CNMG 120416 AH6225 is an ISO‑standard rhombic turning insert designed for medium machining tasks and universal use with rostfreie Stähle.

• PVD‑coated carbide grade AH6225
• 80° rhombic insert with 1.6 mm corner radius
• Double-sided chipbreaker, cylindrical hole
• ISO‑standard CNMG120416 for turning

Consistent cutting performance for medium turning

The CNMG120416 AH6225 indexable insert combines a PVD coating with a wear‑resistant cemented carbide substrate to provide consistent edge strength under changing conditions. The AH6225 grade is formulated as a universal option for rostfreie Stähle, offering a balance between sharpness and robustness; this means reliable engagement when switching between interrupted cuts and continuous finishes. Using a universal grade reduces tool changeovers and simplifies stock management, so production runs remain steady and predictable.

Precision geometry that improves process stability

A defined 80° rhombic form with a 1.6 mm corner radius ensures predictable tool behaviour and contributes to dimensional stability on external and internal turning. The insert’s geometry, combined with the double-sided chipbreaker, promotes controlled chip formation and helps maintain a consistent surface quality. Where surface finish is critical, the combination of stable edge geometry and the PVD layer reduces the risk of built‑up edge and fluctuation in part tolerances, supporting higher first‑pass yields and less rework.

Seamless integration with ISO holders and clamping systems

Compatibility with toolholders is determined by form, clearance angle, tolerance class, attachment method, size and thickness; the CNMG format follows ISO conventions to ease selection of matching external holders or boring bars. The presence of a cylindrical hole and standard thickness simplifies secure clamping and repeatable seating, reducing setup time. Choosing inserts that match holder specifications minimises vibration and improves tool life, making the workflow more efficient and less prone to stoppages.

Practical advantages for mixed‑material shops

For workshops processing a range of rostfreie Stähle and mixed batches, this insert delivers predictable wear behaviour and straightforward grade assignment. The reversible, double‑sided design doubles effective cutting edge life per insert and contributes to lower tooling cost per component. In short production runs or mixed production environments, the universal nature of the grade and the chip control features support quick changeovers and steady productivity without sacrificing surface integrity.

FAQ

What materials is this insert intended for?
The CNMG 120416 AH6225 turning insert by Tungaloy is specified as a universal grade for rostfreie Stähle and performs well in medium turning operations across varied stainless steel compositions.

Is the insert reversible and how does that affect economy?
Yes, the CNMG format is double‑sided; using both edges of the indexable insert effectively doubles the number of available cutting edges and reduces tooling cost per part.

How is holder compatibility ensured for this ISO insert?
Compatibility is ensured by matching the CNMG form, clearance/freiwinkel, tolerance class, attachment and plate thickness to the holder; the ISO designation CNMG120416 aids straightforward selection of the correct external holder or boring bar.

Does the PVD coating improve wear resistance on rostfreie Stähle?
The PVD coating on the cemented carbide substrate enhances abrasion resistance and helps maintain a sharper cutting edge under the thermal and adhesive conditions typical of rostfreie Stähle.
