DCGT070201 AH725 Tungaloy indexable turning insert — ISO rhombic, PVD‑coated carbide for turning

DCGT070201 AH725 Tungaloy is an ISO‑standard rhombic indexable insert designed for external and internal turning applications in workshop and production environments.

• ISO rhombic insert DCGT070201 AH725
• PVD‑coated carbide for steel and stainless steel
• 7° relief angle with 0.1 mm corner radius
• Central hole with cylindrical bore and countersink

Proven process reliability from PVD‑coated AH725

The PVD‑coated grade AH725 offers a balance between toughness and wear resistance that supports fluctuating workpiece materials and smaller tool assemblies. The coating improves surface hardness and heat resistance, which in turn enhances tool life and reduces the risk of built‑up edge when machining both steel and stainless steels. For production runs where material mixes or demanding part tolerances occur, this coated carbide solution provides more consistent cycle times and fewer tool changes, supporting a smoother workflow and predictable output.

Geometry engineered for accurate turning and repeatable finishes

The rhombic plate form with a nominal 55° included angle and a 7° relief angle yields a reliable cutting edge engagement and controlled chip flow. The 0.1 mm corner radius helps produce a defined edge profile while limiting cutting forces for thin‑walled or delicate components. Compatibility with toolholders is governed by form, clearance angle, tolerance class, fastening method, size and plate thickness; using an appropriately matched holder ensures that the insert’s geometry converts directly into repeatable dimensional accuracy and improved surface quality on turned parts.

System integration and application guidance for efficient use

The insert functions as part of an indexable system comprising the ISO‑form plate, a matching external holder or boring bar, a locator/locking set and replacement screws. The single‑sided chipbreaker design is intended to control chips during standard turning operations and to simplify regrinding or indexing procedures. The grade is particularly suitable where process security is paramount: it tolerates minor variations in feed and speed better than uncoated grades and is a practical choice for jobbers and production shops handling a mix of steel and stainless steels. For less experienced staff, the concept of an indexable insert means quick edge renewal by rotation rather than complex regrinding, reducing downtime between parts.

FAQ

What materials is this insert suitable for?
The DCGT070201 AH725 Tungaloy insert is designed for machining steel and stainless steels, offering stable chip formation across these materials.

How does the AH725 coating benefit production runs?
The AH725 PVD coating on the insert increases wear resistance and thermal stability, which extends edge life and supports consistent cycle times during longer or mixed‑material runs.

What does the 0.1 mm corner radius mean for part quality?
A 0.1 mm corner radius provides a fine, repeatable edge profile that improves surface finish while keeping cutting forces moderate, suitable for precision turning and thin‑walled components.

Is the insert compatible with all ISO DCGT holders?
Compatibility depends on holder form, clearance angle, tolerance class, fastening and plate thickness; the insert follows ISO geometry, so matching an ISO‑rated DCGT holder delivers correct seating and clamping.

How is the insert mounted and secured?
The plate is usually mounted with a suitable clamp/locating kit and screw; the central hole with a cylindrical bore and one‑sided countersink allows standard ISO‑style fastening for secure seating.
