DCMT 070204 AH725 turning indexable insert for Drehen by Tungaloy — PVD-coated carbide, 7° clearance

DCMT 070204 AH725 is an ISO‑standard rhombic turning insert designed for external and internal turning operations where process security and material versatility are required

• PVD-coated cemented carbide AH725
• Universal grade for Stahl and rostfreier Stahl
• Rhombic ISO insert, 55° cutting angle
• One-sided chipbreaker, cylindrical hole with countersink

Consistent process security through PVD coating and AH725 grade

The AH725 grade combines a PVD-coated surface with a tough carbide substrate to reduce flank wear and improve edge stability. This results in greater reliability when machining mixed batches of Stahl and rostfreier Stahl, especially in setups where tool change frequency and part variety demand a universally resistant grade. The coating also helps to maintain consistent cutting performance under fluctuating cutting conditions, which supports predictable productivity.

Geometry that delivers accuracy with small‑radius features

With a 55° cutting angle and a 0.4 mm radius, the rhombic DCMT070204 geometry provides the balance between edge strength and form accuracy needed for detail work and finishing passes. The 2.38 mm plate thickness contributes to stable seating in the toolholder, while the ISO 07 size offers a compact profile for confined setups. Together, these geometric attributes reduce vibration and support repeatable dimensional results on turned components.

Secure clamping and straightforward integration into ISO systems

The insert is supplied with hole and a cylindrical hole + one‑side countersink (40°–60°) which enables positive clamping and easy indexing in a wide range of external holders and boring bars. As an ISO‑specified plate, compatibility with the holder is determined by form, clearance angle, tolerance class, fixation method, size and thickness — a modular system approach that simplifies tool inventory and reduces downtime when replacing worn inserts.

Choose AH725 where stability and versatility matter

This universal, chip‑resistant grade is particularly suitable for smaller tools and applications demanding high process security rather than extreme metal removal rates. Paired with an appropriate chipbreaker chosen for the workpiece and machining stability, the insert supports consistent surface quality and reduced risk of edge breakouts. Selecting this grade helps to streamline production when component materials vary within a batch.

FAQ

What materials is this insert suitable for?
The DCMT 070204 AH725 insert from Tungaloy is intended for a broad range of Stahl and rostfreier Stahl applications owing to its universal, chip‑resistant AH725 grade.

How does the hole and countersink affect clamping?
The cylindrical hole with a one‑side countersink (40°–60°) ensures secure seating and positive clamping in standard ISO toolholders, reducing the risk of insert movement during turning.

Which chipbreaker should be chosen for finishing cuts?
For finishing operations, select a chipbreaker with a gentler profile matched to the stability of the setup; the one‑sided chipbreaker on this insert supports controlled chip formation for improved surface quality.

Is this insert compatible with all DCMT holders?
Compatibility depends on holder design — form, clearance angle, tolerance class, fixation method, size and thickness must match the insert; verify holder specifications against the ISO DCMT070204 dimensions.

Can the grade handle interrupted cuts or unstable setups?
The AH725 PVD‑coated carbide is engineered for process security and improved edge stability, making it more tolerant of variable conditions than uncoated grades, though extreme interruptions still require suitable machining parameters.
