CNMG 120404 AH8015 ISO turning insert for turning — Tungaloy

The CNMG120404 AH8015 is an ISO-standard rhombic turning insert designed for external and internal turning of heat-resistant alloys and general turning tasks.

• ISO CNMG 120404 rhombic insert
• PVD-coated AH8015 carbide grade
• Double-sided with cylindrical locating hole
• 80° geometry, 0° clearance angle

Longer tool life on heat-resistant alloys through balanced grade design

The AH8015 grade is a PVD-coated carbide composition engineered as a first choice for the general machining of heat-resistant alloys. The coating enhances wear resistance while the substrate preserves cutting-edge stability, so the insert delivers a reliable service life under higher temperatures. This results in fewer tool changes and steadier cycle times, supporting measurable productivity gains in serial production. The combination of coating and substrate enables a compromise between abrasion resistance and edge toughness, reducing unexpected edge chipping during interrupted cuts.

Predictable fit and secure clamping for fast tool changes

Manufactured to ISO dimensions and tolerance classes, the rhombic shape and the cylindrical locating hole ensure consistent seating in standard CNMG holders. The 80° cutting geometry and a 0° clearance angle make the insert suitable for a wide range of turning setups, while the 4.76 mm plate thickness and 12 mm inscribed size give mechanical stability in heavier cuts. These standardised interfaces simplify tool management: inserts are interchangeable across compatible holders, setup times are reduced, and repeatability between shifts is improved. The accurate geometry aids clamping reliability and predictable tool offsets in CNC programmes.

Better chip control and surface quality with optimised geometry

This double-sided insert features a double-sided chipbreaker and a 0.4 mm corner radius, designed to moderate chip formation and support consistent surface finish in many steels and alloys. The chipbreaker channels and edge preparation guide metal flow away from the cut, decreasing rework and the need for manual chip clearing. For workshops, this translates into lower machine downtime and improved safety at the turret. Select the chipbreaker and grade according to material, machining type and rigidity to obtain the best compromise between feed rate, cutting speed and finish.

FAQ

What materials is this insert best suited for?
The CNMG120404 AH8015 insert is optimised for heat-resistant alloys and general-purpose turning; the AH8015 grade balances wear resistance and edge stability for such materials.

Can this insert be used in any CNMG holder?
Compatibility depends on holder form, clearance angle, tolerance class, clamping method, size and thickness; the CNMG120404 designation follows ISO dimensions to ensure fit with standard CNMG holders when those criteria match.

How does the chipbreaker affect machining performance?
The double-sided chipbreaker controls metal flow and reduces long, stringy chips, improving surface finish and reducing downtime for chip clearing during turning operations.

Is the coating type suitable for high-temperature applications?
The PVD coating on the AH8015 grade increases wear resistance at elevated temperatures, making the insert a suitable option for machining heat-resistant alloys under appropriate cutting conditions.

What is the benefit of the 0.4 mm corner radius?
A 0.4 mm corner radius offers a compromise between edge strength and surface finish, helping to resist chipping while producing an acceptable external finish in most general turning tasks.
