Take advantage of the combination of a PVD-coated AH725 grade, a robust 0.8 mm corner radius and ISO compatibility for consistent turning results and high process security; order the DCMT070208 AH725 indexable insert directly via Metav Werkzeuge or ask the consultants if additional guidance is needed.

DCMT 070208 AH725 indexable turning insert — ISO rhombic, PVD-coated carbide (Tungaloy)

The DCMT070208 AH725 indexable insert is a rhombic, ISO‑standard turning insert designed for external and internal turning where stable chip formation and process reliability are required.

• PVD-coated AH725 universal grade
• 0.8 mm corner radius for robust edges
• 7° clearance with 55° rhombic geometry
• One-sided chipbreaker with countersunk hole

Consistent cutting performance for mixed steels

The insert’s PVD-coated AH725 substrate combines wear resistance with toughness to deliver stable cutting forces across varied workpiece materials, including plain steel and rostfreier Stahl. The coating reduces built-up edge and extends effective tool life, while the 0.8 mm corner radius supports edge strength during interrupted cuts. This results in fewer index changes and more predictable cycle times, which is especially valuable for small‑to‑medium batch production and mixed‑material machining.

Reliable chip control and improved process security

A dedicated one-sided chipbreaker and the rhombic 55° geometry promote predictable chip formation and evacuation. The cylindrical hole with a one-sided countersink (40°–60°) ensures secure clamping and repeatable seat location, reducing micro‑vibration and improving surface finish. Together these features raise process security, meaning fewer stoppages for rework and a steadier output quality when turning components.

Clear compatibility and mounting guidance for fast setup

Compliance with ISO standards simplifies matching the insert to a suitable external holder or boring bar: form, relief (7° clearance), tolerance class, fastening type, size and thickness determine compatibility. The insert’s 2.38 mm thickness and the ISO designation allow rapid selection of a compatible holder, while the standardised hole and countersink geometry enable consistent torque and clamping stability during operation.

Materials, coating and application explained

Made from carbide with a PVD finish identified as AH725, the grade is tuned for universal, breakout‑resistant performance on steel and rostfreier Stahl, making it suitable where workpiece materials change or where smaller tooling requires robust edge behaviour. The combination of substrate and coating emphasises long tool life without sacrificing toughness; for high‑feed or heavy interrupted cuts, selecting a matching holder with adequate rigidity will amplify the grade’s benefits.

FAQ

What applications suit this insert best?
The DCMT070208 AH725 indexable insert is designed primarily for external and internal turning where reliable chip control and process security are required; it performs well on steel and rostfreier Stahl.

How does the AH725 grade affect tool life?
The AH725 PVD coating on the carbide substrate increases wear resistance and reduces built-up edge, so the DCMT070208 AH725 insert typically delivers longer in‑service life under varied turning conditions.

Which holders are compatible with this ISO insert?
Compatibility is determined by the insert’s form, clearance angle, tolerance class, fastening type, size (07) and thickness (2.38 mm); select an ISO‑matched external holder or boring bar that accepts DCMT‑style rhombic inserts.

Is the insert suitable for interrupted cuts and mixed materials?
Yes; the 0.8 mm corner radius and breakout‑resistant AH725 grade make the insert robust for interrupted cuts and versatile across mixed materials.

What clamping features ensure repeatable mounting?
The cylindrical hole with one‑sided countersink (40°–60°) ensures secure and repeatable seating when used with the appropriate clamping set and screw.
