CNMG120412 AH8015 Tungaloy turning insert — PVD-coated carbide, rhombic 80°

The CNMG120412 AH8015 Tungaloy turning insert is an ISO-standard rhombic indexable insert designed for external and internal turning in conventional and slightly demanding setups.

• ISO-standard rhombic shape 80°
• PVD-coated carbide grade AH8015
• 1.2 mm corner radius for robust cuts
• Double-sided with cylindrical hole

Consistent edge life through balanced grade and coating

The combination of a PVD-coated finish and carbide substrate in grade AH8015 produces a balanced performance between wear resistance and edge stability. This results in predictable tool life and fewer indexings during batch runs. For shops machining heat-resistant alloys, the composition of the grade helps to maintain a sharp cutting edge under elevated temperatures, which translates into longer uninterrupted cycles and lower tooling-related downtime.

Easy integration with standard turning systems

Built to ISO dimensions, the insert’s rhombic geometry with an 80° included angle and 0° clearance angle allows straightforward mounting in standard external holders and boring bars. Compatibility is governed by form, clearance angle, tolerance class, fastening method, size and thickness; recognising these parameters at the tooling stage simplifies holder selection and reduces setup time. The cylindrical hole ensures secure clamping and repeatable location when paired with the correct clamping kit.

Improved productivity via chip control and indexability

The double-sided design with an integrated chipbreaker optimises chip formation and evacuation in a variety of feed and speed ranges. Stable chip behaviour reduces the risk of surface damage and improves process security, especially during longer cuts. The 1.2 mm corner radius contributes to mechanical strength at the cutting edge, enabling more aggressive feed choices where appropriate without sacrificing surface integrity.

Application guidance and selection advice

Selected as a first choice for general machining of heat-resistant alloys, this insert performs well in both external and internal turning operations when paired with a suitable holder and cutting data. When uncertain about the best chipbreaker or feed rates for a specific alloy, consult technical data sheets and choose a chipbreaker and grade that match workpiece stability and required surface finish.

FAQ

What materials is this insert suited for?
The CNMG120412 AH8015 Tungaloy insert is designed primarily for the general machining of heat-resistant alloys, offering a balance of wear resistance and edge strength thanks to its AH8015 grade and PVD coating.

How does the double-sided design affect tool life?
A double-sided configuration extends usable life by allowing reversible indexing; the CNMG120412 AH8015 insert provides additional service life through its reversible geometry and robust corner radius.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; using an ISO-compatible external holder or boring bar that accepts CNMG inserts ensures correct clamping of the CNMG120412 AH8015 Tungaloy insert.

What is the benefit of the 1.2 mm corner radius?
The 1.2 mm corner radius increases edge strength, permitting higher feed rates and improved resistance to chipping during interrupted cuts when machining with the CNMG120412 AH8015 insert.

Is the insert suitable for internal turning and boring?
Yes; the ISO rhombic form and cylindrical hole make the insert applicable for both external and internal turning operations when used with the appropriate boring bar or internal holder.
