CNMG090404 AH120 Tungaloy turning insert — PVD-coated carbide, 0.4 mm radius

The CNMG090404 AH120 Tungaloy insert is an ISO-compliant rhombic turning insert designed for external and internal turning where a sharp cutting edge and high process reliability are required.

• PVD-coated carbide grade AH120
• 0.4 mm corner radius for accurate profiles
• Rhombic CNMG shape, 80° cutting geometry

Consistent cutting performance for stable production

The combination of a PVD-coated carbide grade and the CNMG geometry delivers stable wear behaviour and reduced risk of chipping during standard turning tasks. The coated hardmetal layer of the AH120 grade is optimised for wear and fracture resistance, which supports longer tool life and fewer interruptions. The ISO-standard form ensures predictable seating in compatible holders; compatibility depends on form, relief angle, tolerance class, fastening method, size and plate thickness, and the insert is intended to be used together with a suitable external holder, shim/clamp set and replacement screws.

Accurate profiles and dependable surface quality

A 0.4 mm corner radius produces precise contouring and improved surface finish while balancing cutting forces; for fine finishing or light profiling, this radius provides the necessary geometry without sacrificing edge stability. The insert’s double-sided chipbreaker contributes to consistent chip formation across a range of feeds and depths, easing chip evacuation and protecting the cutting edge. The cylindrical mounting hole and a plate thickness of 4.76 mm increase rigidity at the cutting point, which reduces vibration and helps achieve repeatable dimensional accuracy.

Practical integration and application advice

The insert is suitable for general turning applications and can be applied to both external and internal operations when combined with the correct holder and workpiece setup. Selection of the chipbreaker and grade should match the workpiece material, machining type and setup stability—choosing the AH120 grade and a matching chipbreaker will be advantageous when both a sharp edge and process security are required. For situations with variable workpiece materials or limited clamping stiffness, preference for a slightly lighter cutting engagement and closely matched holder geometry will improve performance and extend service intervals.

FAQ

What work does this insert suit best?
The CNMG090404 AH120 Tungaloy insert is intended for external and internal turning where a sharp cutting edge and reliable process control are required.

Which materials can be machined with this grade?
The AH120 PVD-coated carbide grade is designed for broad application and provides good wear and fracture resistance for a wide range of steels and alloyed materials when correctly matched with the chipbreaker and cutting parameters.

How is the insert mounted?
The insert uses a cylindrical mounting hole; secure seating with the corresponding external holder, shim/clamp set and replacement screws is required for stable operation.

How does the 0.4 mm corner radius affect finishing?
A 0.4 mm radius offers a balance between edge strength and surface finish, enabling accurate profiles while maintaining sufficient edge stability for many turning tasks.

Is the insert indexable or single-use?
This CNMG geometry is double-sided and indexable; both sides can be used until the cutting edges reach their wear limit.
