TPMN 220408 AH120 Indexable Turning Insert for Turning — Tungaloy

The TPMN220408 AH120 is an ISO-standard indexable insert designed for reliable external and internal turning where a sharp cutting edge and process security are required.

• PVD-coated carbide for wear resistance
• Sharp cutting edge for reliable chip formation
• ISO‑standard triangle insert, 22 mm across flats
• 11° relief angle with 0.8 mm corner radius

Consistent cutting performance for production turning

The TPMN220408 is manufactured to ISO dimensions, which ensures predictable seating and repeatable clamping in standard toolholders. The PVD-coated carbide grade AH120 delivers a balance between wear resistance and edge stability, reducing unexpected tool changes in high-volume turning. With a defined 11° relief angle, the insert maintains a clean shear geometry that supports consistent surface finish and lowers vibration risk during both external and internal operations.

Improved uptime through a wear-resistant grade

A PVD finish combined with a robust carbide substrate results in superior wear resistance and edge retention compared with uncoated grades; this directly translates into longer uninterrupted runs and fewer indexings. The cutting geometry supports stable chip formation without an integrated chipbreaker, so the choice of holder and cutting parameters becomes central to optimising chip control. For workshops seeking economic performance, the process security afforded by this grade helps reduce scrap and rework.

Straightforward integration into ISO tool systems

The triangular shape and 22 mm size match common ISO insert pockets; the 4.76 mm thickness and “no hole” configuration suit clamping systems that rely on precise seat contact and screw fixation. A 0.8 mm corner radius provides a robust cutting edge that tolerates moderate feed rates while preserving finishing capability. Compatibility is determined by insert form, relief, tolerance class, fixing method, size and thickness — replace or pair with the appropriate holder, underlay and clamping set for reliable results.

FAQ

What materials is this insert suitable for?
The TPMN220408 AH120 insert is a PVD-coated carbide grade engineered for general turning applications; suitability depends on the specific workpiece material and cutting data selection.

How does the AH120 grade improve production?
AH120 offers a wear-resistant, process-secure cutting edge that helps extend tool life and reduce unplanned interruptions during continuous turning operations.

Which toolholders are compatible with this insert?
Compatibility is determined by ISO form, relief angle, tolerance class, fixing method, size and thickness; select a holder that matches the ISO triangular insert pocket and clamping system.

Is a chipbreaker included with the insert?
This particular insert is supplied without a chipbreaker; chip control should be achieved via the holder geometry and cutting parameters.

Can the insert be used for both external and internal turning?
Yes, the design supports both external and internal turning when paired with the correct holder and process parameters.
