DCMT11T308 AH905 ISO turning insert for turning — Tungaloy

DCMT11T308 AH905 is an ISO-design turning insert developed for external and internal turning operations, offering a stable cutting edge and high process security.

• PVD-coated carbide grade AH905
• Single-sided chipbreaker for stable chips
• Rhomboid insert with 55° cutting angle
• 0.8 mm corner radius for precise engagement

Reliable performance for productive turning

The PVD-coated carbide grade AH905 delivers consistent wear resistance and a refined cutting edge suited to a wide range of turning tasks. Designed for ISO compatibility, this insert supports predictable cycle times and reduced tool changes, which helps to lower non-productive time. The combination of a sharp cutting geometry and a single-sided chipbreaker promotes controlled chip formation during both external and internal turning, improving surface finish and reducing the likelihood of edge chipping. These technical properties translate directly into higher throughput and improved process stability on the shop floor.

Durable grade and coating for longer tool life

The advanced AH905 substrate and PVD coating provide a balance between toughness and wear resistance, making the insert appropriate where a sharp edge and process security are required. The coated hardmetal substrate resists flank wear while maintaining edge integrity, which is particularly beneficial when facing interrupted cuts or variable component batches. As a result, maintenance intervals can be extended and tool management simplified, supporting cost-effective production and consistent component quality without compromising machining performance.

Practical compatibility and easy integration with holders

As an ISO-format rhomboid insert, the geometry and fixation features ensure straightforward replacement in compatible holders; compatibility depends on form, clearance angle, tolerance class, fastening, size and thickness. The rhomboid shape with a 55° cutting angle and a 0.8 mm radius allows precise engagement in a wide variety of turning setups. The insert’s 3.97 mm thickness and the cylindrical hole with a single-sided countersink (40°–60°) ensure secure clamping and repeatable seating. These characteristics make selection and stock management simpler in production environments that rely on standardised tooling systems.

Application guidance for better outcomes

Select the single-sided chipbreaker and the AH905 grade when a sharp cutting edge and robust process reliability are priorities; this combination is particularly effective for general-purpose turning across a range of steels and cast materials. For optimal results, match the insert geometry and chipbreaker style to the workpiece material and the rigidity of the setup. When in doubt, consult machining data sheets and consider small trial cuts to fine-tune cutting parameters — this approach reduces scrap and shortens time to stable production.

FAQ

What materials is this insert suitable for?
The DCMT11T308 AH905 insert is designed as a versatile turning grade; the AH905 PVD-coated carbide offers good wear resistance and process security for common steels and mixed production runs.

How does the single-sided chipbreaker affect machining?
A single-sided chipbreaker on this insert promotes consistent chip control and reduces the risk of entanglement, improving surface finish and stable cutting forces during turning.

Which holders are compatible with this ISO insert?
Compatibility requires a matching ISO rhomboid pocket and consideration of form, clearance angle, tolerance class, fastening, size and thickness; the insert’s dimensions (11 mm size, 3.97 mm thickness) and hole configuration support standard ISO holders.

What is the benefit of the 0.8 mm corner radius?
The 0.8 mm corner radius provides a compromise between edge strength and profile fidelity, offering precise engagement and reduced risk of edge chipping compared with very small radii.
