CNMG120404 AH8015 Tungaloy turning insert — ISO CNMG, 80° rhombic

The CNMG120404 AH8015 Tungaloy is an ISO rhombic turning insert designed for general machining and turning of heat‑resistant alloys, offering reliable edge life and consistent chip control.

• PVD-coated carbide AH8015 for heat-resistant alloys
• 80° rhombic CNMG form with 0.4 mm nose radius
• Double-sided chipbreaker for versatile turning
• Cylindrical hole and 4.76 mm plate thickness

Consistent performance where heat resistance matters

The combination of a PVD-coated surface and a cemented carbide substrate in grade AH8015 provides a robust balance between wear resistance and cutting edge stability. That balance is particularly valuable when machining nickel‑based and other heat‑resistant alloys, where temperatures at the cutting edge can accelerate wear. In practice, the coated grade reduces flank wear and helps maintain a steady cutting profile, so fewer insert changes are required and component tolerances remain consistent. The design is optimised for productive turning operations while preserving surface finish quality.

Designed geometry for secure mounting and reliable chip control

The ISO CNMG form, with its 80° cutting angle and 0.4 mm nose radius, gives a useful compromise between strength and precision for both external and internal turning. The rhombic geometry and the cylindrical locating hole ensure repeatable seating in compatible holders; compatibility is determined by form, relief angle, tolerance class, fastening, size and thickness. The double‑sided chipbreaker supports predictable chip formation across a range of cutting conditions, improving productivity and reducing downtime related to chip handling.

Practical benefits for workshop productivity

Using this insert in a properly matched holder and clamping set helps to achieve steady cuts and prolonged tool life. The 4.76 mm plate thickness adds rigidity in interrupted cuts or heavier depths of cut, while the neutral 0° clearance angle is suitable for a variety of turning tasks when combined with the right holder geometry. Selection of grade AH8015 is a first choice for general machining of heat‑resistant materials because it balances wear resistance with edge toughness, which supports both stable cutting and reproducible results across serial production.

Application guidance and material suitability

Typical applications include external and internal turning where heat resistance and edge stability are required. The insert works well for components produced from heat‑resistant alloys; it can be paired with suitable holders and clamping sets as part of an ISO‑based system. When choosing parameters, favour moderate feeds with cutting speeds adapted to the workpiece alloy and cooling strategy; the PVD coating helps where elevated temperatures occur. For complex setups, verify holder compatibility and clamping torque to ensure consistent repeatability.

FAQ

How suitable is this insert for heat‑resistant alloys?
The CNMG120404 AH8015 Tungaloy insert is specifically graded (AH8015, PVD-coated) for general machining of heat‑resistant alloys and offers a compromise of wear resistance and edge stability suited to such materials.

Can this insert be used for both external and internal turning?
Yes, the rhombic CNMG form and double‑sided chipbreaker make the insert appropriate for both external and internal turning operations when used with a compatible holder.

What determines compatibility with a toolholder?
Compatibility depends on the insert form, clearance angle, tolerance class, fastening method, size and thickness; checking these parameters against the chosen holder ensures correct seating and repeatable results.

Is the insert reversible or single-use per edge?
The CNMG geometry is double-sided, allowing the use of multiple cutting edges before replacement; correct indexing extends productive life per insert.

What additional components are needed for a complete cutting system?
A compatible external holder or boring bar, a backing/support pad or clamping set, and replacement screws are typical components of the system when fitting ISO turning inserts.
