DCMT 070204 AH6225 indexable turning insert for turning by Tungaloy — PVD‑coated carbide, 55°

The DCMT070204 AH6225 is an ISO rhombic indexable turning insert designed for external and internal turning, optimised for medium‑duty operations and variable cutting conditions.

• PVD‑coated carbide for edge stability
• Universal grade for rostfreier Stahl
• 55° geometry for reliable engagement
• 0.4 mm corner radius for versatile finishes

Consistent medium‑machining performance that reduces cycle time

The PVD‑coated carbide grade AH6225 delivers a sharp yet robust cutting edge, engineered for changing conditions commonly found in medium turning operations. The coating improves wear resistance and thermal stability, which prolongs tool life and maintains dimensional accuracy over longer runs. For production environments seeking stable performance without frequent insert changes, this indexable solution offers an efficient balance between cutting speed and tool life, helping to lower per‑part machining costs.

Secure fit and compatibility for straightforward tool setup

The insert follows ISO standards and a rhombic plate geometry, so holder compatibility is determined by form, relief angle, tolerance class, fastening method, size and thickness. The 55° main angle and 7° relief angle ensure predictable cutting forces and simple seat alignment. The insert features a cylindrical hole with a single‑sided countersink (40°–60°) for secure clamping and accurate repeatability, reducing set‑up time and increasing process reliability across batch changes.

Chip control and surface quality tuned for rostfreier Stahl

A single‑sided chipbreaker combined with the 0.4 mm corner radius provides controlled chip formation and consistent surface finish in medium operations. The geometry supports smooth chip evacuation, lowering the risk of built‑up edge and improving surface integrity on rostfreier Stahl. For users less familiar with insert geometry, the corner radius influences both strength and finish: a 0.4 mm radius is a compromise that supports both robustness and good finishes without excessive cutting forces.

Practical selection advice and maintenance tips

When selecting a holder, match form and size to the insert dimensions to ensure correct rake and clearance angles; incorrect mating can negate the benefits of the PVD‑coated grade. Store spare inserts in a dry, organised system and inspect inserts visually for edge chipping before re‑use. For fluctuating production demands, the universal nature of this grade allows one insert type to be applied across several rostfreier Stahl families, simplifying inventory while maintaining process performance.

FAQ

What materials is this insert best suited for?
The DCMT070204 AH6225 insert is a universal grade optimised for rostfreier Stahl and provides balanced performance for medium turning operations.

How does the PVD coating benefit machining?
The PVD‑coated carbide in the AH6225 grade increases wear resistance and thermal stability, which helps maintain edge life and consistent part quality when using the DCMT070204 insert.

Which holders are compatible with this insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; ensure holders accept an ISO rhombic size 07 plate with 2.38 mm thickness.

What surface finish can be expected with a 0.4 mm corner radius?
A 0.4 mm corner radius on this insert balances edge strength and finish, enabling good surface quality during medium machining without excessive cutting forces.

Is the insert suitable for both internal and external turning?
Yes, the DCMT070204 AH6225 is designed for both external and internal turning applications when paired with a suitable holder and machining parameters.
