DNMG150412 AH8015 Tungaloy insert — ISO rhombic turning insert, PVD-coated carbide, 55° lead angle

DNMG150412 AH8015 Tungaloy insert is an ISO-standard rhombic indexable insert designed for general turning, offering a balanced mix of wear resistance and edge stability for demanding materials.

• ISO-standard rhombic 55° cutting geometry
• PVD-coated AH8015 carbide grade
• Double-sided chipbreaker for chip control
• 1.2 mm corner radius for robust cutting

Predictable tool life through a balanced PVD-coated grade

The AH8015 designation denotes a PVD-coated carbide grade engineered for the general machining of heat-resistant alloys, where a compromise between wear resistance and edge stability is essential. This balanced composition reduces flank wear under cyclic thermal loads and extends productive cutting intervals, which translates into fewer tool changes and more consistent batch-to-batch results. The insert’s coating also supports reliable surface finish across longer tool life.

Stable cutting forces and access from the rhombic 55° geometry

A rhombic 55° geometry gives the insert a favourable compromise between cutting-force distribution and access to shoulder and profile areas. The 1.2 mm corner radius helps to absorb intermittent loads, improving stability where fixture rigidity is limited. The 4.76 mm plate thickness combined with a 0° clearance angle ensures secure seating in the toolholder; the cylindrical locating hole provides positive positioning and repeatability when clamped in compatible holders.

Consistent chip control and straightforward system integration

The double-sided chipbreaker is designed to form short, controllable chips across a range of cutting parameters. Good chip control reduces re-cutting and avoids edge damage, particularly when machining tougher alloys. As an ISO indexable insert, the component forms part of a system that requires a matching external holder or boring bar, plus a shim/clamping set and replacement screws; choosing the correct holder form, rake and tolerance class is decisive for optimum performance.

Practical handling and application guidance for machining shops

Being double-sided and ISO-standard makes the insert economical in inventory management and quick to replace, reducing downtime during tool changes. For best results, select the chipbreaker and grade according to the workpiece material, cutting style and machine stability; the AH8015 grade is a first choice for many heat-resistant materials.

FAQ

Is this insert suitable for external and internal turning? Yes. The DNMG150412 AH8015 Tungaloy insert is designed for both external and internal turning applications when used with a compatible holder and correct clamping.

Which materials are best machined with the AH8015 grade? AH8015 is a PVD-coated carbide grade optimised for heat-resistant alloys and general-purpose machining where a balance of wear resistance and edge stability is required.

How does the 55° geometry affect cutting behaviour? A 55° lead angle reduces radial cutting forces and improves access to shoulders and profiles, which enhances stability and surface finish when machining interrupted cuts.

What does the double-sided chipbreaker mean in practice? The double-sided chipbreaker provides consistent chip formation on usable faces, supporting safer chip control and extending the effective life of the cutting edges when set up correctly.

What components are needed to use this ISO insert? Assembly requires a compatible external holder or boring bar, an appropriate shim/clamping set and the correct replacement screws; exact holder compatibility depends on form, rake, tolerance class, fastening and thickness.
