DCMT 11T308 AH905 indexable turning insert — Tungaloy

A DCMT11T308 AH905 ISO-standard indexable insert designed for reliable external and internal turning, offering a rhombic 55° geometry and a robust PVD-coated carbide grade.

• PVD-coated AH905 carbide for wear resistance
• 55° rhombic geometry for versatile turning
• 0.8 mm corner radius for precise edge strength
• Cylindrical hole with single-sided countersink

Extended tool life through modern coating and substrate

The combination of a PVD-coated surface and a wear-resistant carbide substrate ensures extended cutting performance under continuous turning cycles. The AH905 grade is engineered to provide a sharp cutting edge while resisting flank wear and micro-chipping; this results in more stable tool life and fewer insert changes during production. For operations where consistent surface finish and repeatable tool life matter, this insert reduces unplanned downtime and supports predictable machining windows.

Geometry and mounting that improve process stability

The rhombic 55° shape, 0.8 mm corner radius and a 7° clearance angle deliver a balance between strength and accessibility for varied turning profiles. The cylindrical hole with a one-sided countersink (40°–60°) provides secure, repeatable clamping in ISO-compatible holders, while the 3.97 mm plate thickness contributes to rigidity under cutting loads. These geometric choices make the insert suitable for finishing and medium turning where edge control and stable clamping are priorities.

System compatibility and application guidance for efficient integration

As an ISO-standard turning insert, compatibility with the toolholder depends on form, clearance, tolerance class, fastening method, size and thickness; the insert is intended for use with a matched external holder or boring bar, appropriate shim/clamp set and replacement screw. The single-sided chipbreaker supports controlled chip formation for many common steels and alloyed materials; selecting the correct chipbreaker and grade ensures optimal chip evacuation and surface quality. For complex material mixes or specialised cycle requirements, Metav Werkzeuge can advise on holder matching and process parameters to maximise productivity.

FAQ

What materials is the DCMT11T308 AH905 suitable for?
The DCMT11T308 AH905 insert is optimised for a wide range of steels and alloyed materials; the AH905 PVD-coated carbide provides good wear resistance and edge stability for general turning tasks.

How does the 0.8 mm corner radius influence cutting performance?
A 0.8 mm corner radius increases edge strength and improves surface finish stability during medium-depth cuts when using the DCMT11T308 AH905, reducing the risk of micro-chipping at the corner.

Is the insert compatible with ISO holders?
Compatibility is determined by form, clearance, tolerance class, fastening and thickness; the DCMT11T308 AH905 follows ISO standards and is intended for use in matched ISO holders with the appropriate shim and clamping set.
