TNMG220408 AH120 TNMG 220408 indexable turning insert, PVD-coated carbide, 60°

TNMG220408 AH120 is a triangular, ISO‑standard indexable turning insert engineered for general external and internal turning where edge sharpness and process security are priorities.

• PVD-coated carbide AH120
• Double-sided chipbreaker
• Triangular 60° insert form
• 0.8 mm corner radius

Consistent cutting performance and measurable benefits

The combination of a PVD-coated surface with the AH120 grade delivers a balance of wear resistance and edge stability that benefits continuous production. As a carbide insert with a robust coating, the component reduces premature flank wear and helps maintain dimensional accuracy over longer tool intervals. The integrated double-sided chipbreaker supports predictable chip control, which in turn lowers rework rates and contributes to process efficiency. This technical composition makes the insert particularly suitable for operations that prioritise uptime and repeatable results.

Process security through design and ISO compatibility

Compatibility with holders is determined by form, clearance angle, tolerance class, fastening, size and thickness; the ISO‑standard geometry of this insert ensures interchangeability across compliant clamping systems. The neutral 0° clearance angle and the 60° included angle provide a stable cutting geometry that reduces vibration in finish and medium roughing passes. The specification calls for matching the insert to the correct holder, backing pads and screws to achieve the intended rigidity and repeatable clamping force, which supports predictable tool life and machining outcomes.

Practical handling, selection and application guidance

The triangular shape with a cylindrical hole and a plate thickness of 4.76 mm makes fitting straightforward into standard ISO toolholders; the 22 mm size and 0.8 mm corner radius are well suited to producing a balance between edge strength and detail in profiles. For different workpiece materials and cutting conditions, the choice of the AH120 chipbreaker and grade should match the material, machining strategy and machine stability. The insert is recommended for both external and internal turning operations where a sharp, fracture‑resistant edge is required; selection of holder rigidity and cutting parameters will translate the material properties into reliable shopfloor performance.

FAQ

Is this insert compatible with my ISO turning holder?
Compatibility depends on holder geometry; the TNMG220408 AH120 insert follows ISO dimensions, so matching form, clearance angle, tolerance class, fastening and thickness to the holder ensures correct fit and safe clamping.

Which materials is the grade AH120 suitable for?
The AH120 grade on the TNMG220408 is designed as a wear‑ and fracture‑resistant option for turning; the chipbreaker and grade selection should be aligned to the specific workpiece material and machining type for best results.

How should the chipbreaker be chosen for specific jobs?
Select the insert’s chipbreaker based on material, depth of cut and desired surface finish; the double‑sided chipbreaker of this insert offers a balanced solution for reliable swarf control in many turning applications.

What does the 0.8 mm corner radius mean for machining?
A 0.8 mm corner radius provides increased edge strength compared with finer radii, helping to withstand interrupted cuts and providing a good compromise between edge durability and the ability to machine tighter radii.

What is included when ordering this insert?
Orders for the TNMG220408 AH120 include the indexable insert itself; holders, backing pads and fastening screws are sold separately and must be selected according to the holder system and clamping method.
