DCMT 11T308 AH725 – Indexable turning insert, PVD-coated carbide by Tungaloy

A DCMT 11T308 AH725 indexable insert designed for ISO-compliant external and internal turning, suited to Stahl and rostfreier Stahl machining.

• ISO-compatible DCMT geometry for secure clamping
• PVD-coated AH725 grade for broad Stahl applications
• Fracture-resistant chip control for process security

Consistent cutting performance with broad material coverage

The insert combines a PVD-coated surface with a cemented carbide substrate to deliver consistent tool life and stable cutting under variable conditions. The AH725 grade is specified as a universal, outbruchfeste (fracture-resistant) grade suitable for a wide range of Stahl and rostfreier Stahl; this means fewer tool changes when batches include mixed materials. The coating reduces built-up edge and improves wear resistance, which maintains dimensional stability over longer runs and supports higher productivity in serial turning operations.

Secure fit and system compatibility for predictable results

Designed to the ISO turning insert standard, the rhombic form with a 55° included angle and a 7° clearance angle ensures repeatable seat contact and reliable clamping in compatible holders. The geometry and tolerance class determine compatibility with external holders and boring bars; the system typically comprises the ISO insert, a matching holder or boring bar, a shim/clamp set and replacement screws. The insert’s rhombic shape and central hole with a single-sided countersink provide secure location and repeatable seating, which reduces setup time and improves process reproducibility.

Practical advantages in chip control and edge robustness

The one-sided chipbreaker and a corner radius of 0.8 mm balance strength and surface finish: the chipformer directs chips away from the cut while the radius increases edge resilience against fracture, particularly on interrupted cuts or unstable setups. This fracture-resistant behaviour makes the grade especially useful for smaller tooling and applications with high demands on process security. If further guidance is required on holder matching or optimal cutting parameters, technical assistance is available by e‑mail or phone to ensure the insert fits the specific turning task.

FAQ

What applications is this insert intended for?
The Tungaloy DCMT11T308 AH725 indexable turning insert is intended for external and internal turning and is especially suitable where mixed Stahl and rostfreier Stahl workpieces are encountered.

How does the AH725 grade affect performance?
The AH725 PVD-coated grade offers a balance of wear resistance and fracture resistance; in practice the AH725 grade helps maintain dimensional stability and reduces the need for frequent tool changes.

What does the one-sided chipbreaker do?
The one-sided chipbreaker shapes and controls chip flow to prevent entanglement and to ease chip evacuation, improving surface finish and reducing the risk of tool breakage in interrupted cuts.

Which holders are compatible with this insert?
Compatibility depends on insert form, clearance angle, tolerance class, clamping method, size and thickness; the rhombic DCMT geometry and central hole suit standard ISO holders and boring bars that accept 11-size inserts.

How does the corner radius influence results?
A 0.8 mm corner radius increases edge strength and improves surface quality on finishing passes; it is a compromise between durability and achievable finish.
