DNMG150404 AH905 indexable turning insert (55° rhombic) – Tungaloy
The DNMG150404 AH905 is an ISO indexable turning insert for external and internal turning, engineered for applications that demand a sharp cutting edge and consistent process security.
- ISO rhombic insert, 55° cutting edge
- PVD-coated carbide grade AH905
- 0.4 mm corner radius for fine finishing
- Double-sided chipbreaker, with cylindrical hole
Longer tool life through optimised coating and grade
The combination of a PVD coating and the AH905 cemented carbide grade is designed to deliver wear- and fracture-resistant performance during turning operations. The coating reduces flank wear and improves surface finish stability, which in turn lowers tool consumption and increases time between indexings. These properties make the insert a cost-effective option for batch production and mixed-series machining where reproducible results are required.
Geometry that balances precision and versatility
The insert’s 55° geometry and rhombic form provide a versatile cutting angle for both light finishing and more demanding turning tasks. A 0.4 mm corner radius supports fine surface quality while the specified 0° clearance angle and a plate thickness of 4.76 mm ensure mechanical stability in the seat. The double-sided chipbreaker and the cylindrical hole facilitate secure clamping and simple indexing, so the cutting edge can be rotated to use all available edges before replacement.
Smooth integration into ISO tooling systems
Compatibility with holders and boring bars is ensured by standardised dimensions and tolerances: form, clearance angle, tolerance class, fixation, size and thickness determine fit. The typical system comprises an ISO indexable insert, a matching external holder or boring bar, a backing/clamping set and spare screws, all of which are widely available. This standardisation reduces set-up time and minimises stock complexity while maintaining repeatable clamping accuracy.
Practical applications and selection guidance
Designed primarily for turning, the insert suits both external and internal operations when a sharp cutting edge and process security are priorities. Selection of the most effective chipbreaker and grade should be based on the workpiece material and machining stability; the AH905 grade is tailored for stable chip formation and broad material coverage. If clarification is needed regarding compatibility with a specific holder or the optimal chipbreaker for a given alloy, technical data and application advice are available — contact details are provided below for further assistance.

FAQ
What turning tasks is this insert intended for?
The DNMG150404 AH905 indexable turning insert is intended for both external and internal turning where a sharp cutting edge and reliable chip control are required.
Which materials can be machined with this grade?
The AH905 PVD-coated cemented carbide is designed for broad material coverage and stable chip formation; selection of the specific chipbreaker should match the workpiece material and machining conditions.
How does the insert secure to a holder?
The insert uses a cylindrical hole and standard ISO dimensions; clamping and stability depend on matching the holder by form, clearance angle, tolerance class, fixation, size and thickness.
How many cutting edges are available per insert?
The DNMG150404 AH905 is double-sided with indexing on both sides, enabling multiple cutting edges to be used before replacement.
Is the insert suitable for fine finishing?
Yes, the 0.4 mm corner radius and PVD coating support fine surface finishes while maintaining edge life.
