DCMT 11T308 AH725 Tungaloy turning insert — PVD-coated carbide, 55° rhombic geometry

DCMT11T308 AH725 is an ISO-standard rhombic turning insert designed for external and internal turning, offering a universal, breakage-resistant grade optimised for steel and rostfreier Stahl applications.

• ISO rhombic insert, 55° cutting geometry
• PVD-coated carbide grade AH725
• Single-sided chipbreaker for stable chips
• 0.8 mm corner radius for profile control

Consistent performance across varied steels

The PVD-coated carbide AH725 grade delivers a robust balance between wear resistance and toughness, making it well suited to mixed-production environments. The insert DCMT11T308 combines a 55° cutting geometry with a 0.8 mm corner radius, which together reduce edge chipping and encourage stable machining forces. For operations with frequent material changes, this grade helps maintain cycle times and reduces unplanned tool changes through improved process reliability.

Precision geometry for accurate turning results

An ISO rhombic shape with a 55° lead angle provides predictable cutting engagement and favourable chip flow, while the 0.8 mm corner radius supports repeatable profile accuracy on turned features. The moderate relief angle and standardised dimensions enable straightforward programming and predictable toolpath behaviour. When form accuracy is critical, the insert’s geometry aids consistent surface finish and dimensional control without extensive setting adjustments.

Controlled chip formation and secure clamping

The single-sided chipbreaker is designed to manage chip shape for common turning tasks, helping to avoid long, entangling swarf and supporting uninterrupted production. The plate’s hole configuration — a cylindrical hole with a single-sided countersink (40°–60°) — ensures reliable clamping with suitable holders. Compatibility depends on holder shape, clearance angle and tolerance class; selecting the correct seat and clamp prevents vibration and preserves tool life.

System view: integration and practical use

Consider the insert as part of a system: correct pairing with a matched external holder or boring bar, a suitable underlay/clamping kit and replacement screws secures performance. Smaller tooling setups and applications demanding elevated process security particularly benefit from the universal, breakage-resistant nature of this grade. For typical workflows such as facing, external turning and light internal profiling, the insert offers a pragmatic mix of durability and versatility.

FAQ

What materials is this insert best suited for?
The DCMT11T308 AH725 insert is optimised for steel and rostfreier Stahl, offering universal performance across a broad range of steels thanks to the AH725 PVD-coated carbide grade.

Is the insert suitable for internal turning operations?
Yes; the rhombic 55° geometry and the single-sided chipbreaker make it suitable for both external and internal turning, provided a compatible boring bar or holder is used.

How does the AH725 grade affect tool life and reliability?
AH725 is designed as a breakage-resistant, universal grade that balances wear resistance and toughness, enhancing tool life and maintaining process reliability under variable conditions.

What must be checked to ensure proper clamping?
Verify holder seat form, clearance angle and tolerance class; the insert’s cylindrical hole with a one-sided countersink requires a matching clamping arrangement to avoid movement and ensure secure fixation.

Can this insert be used for small toolholders and high-security processes?
Yes; the universal, breakage-resistant properties of the grade make it particularly suitable for smaller tooling setups and applications where process security is a priority.
