DNMG150404 AH8015 — ISO rhombic turning insert, Tungaloy, PVD‑coated carbide

DNMG150404 AH8015 is an ISO rhombic insert engineered for general turning of heat‑resistant alloys and similar demanding materials.

• PVD‑coated carbide grade AH8015
• 55° rhombic geometry for versatile turning
• 0.4 mm corner radius for fine surface finish
• Double-sided chipbreaker for reliable chip control
• Cylindrical centre hole for secure clamping

Consistent performance on heat‑resistant alloys

The PVD‑coated carbide grade AH8015 combines wear resistance with edge stability to extend cutting life when machining heat‑resistant alloys. This balancing act reduces the need for frequent index changes and maintains dimensional accuracy over longer runs. The coating helps limit built‑up edge and increases resistance to thermal load, which translates into fewer interruptions and more predictable productivity in continuous or batch turning operations.

Easy integration into ISO holder systems

The ISO rhombic designation and standardised geometry mean the insert fits common ISO holders when the holder's form, clearance, tolerance class, fastening method, size and thickness are matched. The 55° cutting angle and 0° clearance enable versatile approach angles for both external and internal turning tasks. The cylindrical centre hole and standard fastening ensure secure clamping and repeatable seating, reducing the risk of vibration and chatter for a stable process.

Improved surface finish and controlled chips

A 0.4 mm corner radius delivers a fine surface finish and helps avoid edge chipping in finishing passes, while the double-sided chipbreaker offers consistent chip formation across both indexable edges. For operations that prioritise surface integrity over heavy stock removal, the combination of a small radius and PVD coating minimises surface defects and built‑up edge, resulting in better component appearance and reduced rework.

Practical guidance for turning applications

Designed for external and internal turning, the insert is best used with a matching chipbreaker and grade chosen according to material, cutting conditions and machine rigidity. In practice, select the AH8015 grade when facing heat‑resistant or tougher alloy work; choose a larger radius or different chipbreaker when higher feed or roughing is required. For tailored recommendations on feeds, speeds and holder selection, technical consultation is available to ensure the cutting solution delivers measurable productivity and repeatable quality.

FAQ

What materials is this insert suitable for?
The DNMG150404 AH8015 Tungaloy insert is intended primarily for heat‑resistant alloys and offers a balanced combination of wear resistance and edge stability for general‑purpose machining.

How is the insert secured in the holder?
The insert features a cylindrical centre hole and standard ISO seat geometry; secure clamping is achieved using the corresponding ISO holder, ensuring repeatable seating and stable cutting.

What surface quality can be expected with a 0.4 mm corner radius?
A 0.4 mm corner radius produces a fine surface finish in finishing passes while maintaining edge strength; for heavier stock removal a larger radius or a different chipbreaker may be preferable.

How many indexable edges does the insert provide?
The rhombic DNMG insert is double‑sided with a chipbreaker on each usable edge, allowing for multiple indexing cycles before replacement.
