CNMG 090402 AH6225 — Indexable turning insert for Drehen (Tungaloy)

CNMG 090402 AH6225 is an ISO‑standard, rhombic indexable turning insert designed for external and internal turning of stainless steels and similar materials.

• PVD-coated cemented carbide for stainless steel
• Sharp, stable cutting edge for medium turning
• Double-sided insert with cylindrical hole
• ISO-compliant geometry for standard holders

Consistent machining of stainless steels with a universal grade

The AH6225 grade is a PVD‑coated cemented‑carbide formulation developed for reliable performance when machining rostfreier Stahl. The coating reduces built‑up edge and improves wear resistance under varying cutting conditions, while the substrate provides a balance between toughness and hardness. For medium cutting operations the combination yields improved surface finish and predictable tool life, making this insert suitable for batch and series production where repeatability is essential.

ISO compatibility ensures simple integration into existing tool systems

The insert follows the ISO designation and geometry rules for CNMG‑type inserts, so compatibility with standard external holders and boring bars is determined by form, relief (0° rake angle), tolerance class, clamping method, size and thickness. The rhombic profile with an 80° included angle and cylindrical hole enables secure clamping and straightforward replacement, reducing setup time and simplifying inventory management across machines and toolrooms.

Productivity gains from double‑sided use and optimised edge design

Being double‑sided, the insert offers two effective cutting edges per index, halving the cost per usable edge compared with single‑edged alternatives. The small corner radius (0.2 mm) supports a compromise between edge strength and surface finish, permitting modest depths of cut with stable metal removal. The included chipbreaker geometry is designed to support controlled chip formation, which helps maintain cycle times and reduces the risk of interruption from poor chip evacuation in long or interrupted cuts.

Practical application advice for secure process results

Selection of the correct chipbreaker and grade is decisive: the AH6225 variety performs best in turning operations where a sharp but robust edge is required. Typical uses are external and internal turning of medium‑hard stainless steels and similar alloys. For interrupted cuts or poor workpiece support, choose a slightly larger corner radius or adjust cutting parameters to reduce shock loads. The insert’s PVD coating and carbide substrate work together to sustain edge stability under variable feeds and speeds, helping to avoid premature wear in mixed‑batch production.

FAQ

What applications suit this insert best?
The CNMG 090402 AH6225 insert is designed primarily for external and internal turning, especially for rostfreier Stahl and similar alloys where a sharp, stable edge at medium cutting conditions is required.

Is the insert reversible and how many usable edges are available?
Yes, the insert is double‑sided and provides two cutting edges per index, offering cost‑effective edge rotation and extended service life compared with single‑edged options.

How does the AH6225 grade improve process stability?
The AH6225 PVD coating reduces built‑up edge and enhances wear resistance, while the carbide substrate provides toughness; together they promote consistent cutting behaviour under variable conditions.

Which holder features are essential for correct fitment?
Proper fitment depends on the ISO geometry: correct holder form, clearance angle, tolerance class, clamping method, size and thickness ensure secure seating and repeatable cutting performance with this insert.

Can the insert handle interrupted cuts?
The grade provides a balance of sharpness and toughness, but for severe interruption a larger corner radius or adjusted cutting parameters is advisable to avoid edge chipping.
