TNMG 220408 AH6235 turning insert – ISO‑standard triangular insert for turning by Tungaloy

A TNMG220408 AH6235 indexable insert designed for ISO‑standard turning operations, offering robust performance for stainless steel and interrupted cuts with a double‑sided chipbreaker and cylindrical hole for secure fastening.

• ISO‑standard triangular insert
• PVD‑coated carbide grade AH6235
• Suited for stainless steel and interrupted cuts
• Double‑sided chipbreaker for reliable control

Increased process reliability through material and coating

The combination of a PVD‑coated carbide substrate and the AH6235 grade delivers a balanced performance that emphasises tool life and edge stability. The coating reduces adhesive wear on the cutting edge while the substrate toughness prevents premature chipping during interrupted cuts. For turning operations on stainless steel, this results in fewer tool changes and more predictable cycle times, which supports higher machine utilisation and lower per‑part machining cost.

Secure cutting geometry for repeatable results

Engineered as an ISO‑standard triangular insert with a corner radius 0.8 mm and a 60° included angle, the geometry provides a compromise between edge strength and dimensional control. The 0° relief angle helps maintain cutting stability in radial engagement, while the cylindrical hole and standard mount compatibility ensure consistent seating in appropriate clamping systems. This repeatability is crucial when producing series components where tolerance adherence and surface quality are measured attributes.

Practical advantages from chip control and design

The insert’s double‑sided chipbreaker reduces chip length and improves chip evacuation in common turning tasks, lowering the risk of entanglement and surface damage. The triangular form allows two usable edges per side and multiple edge indexings, extending effective edge life before replacement. These design features combine to support uninterrupted production runs and simplified tool inventory management.

Compatibility, selection and application guidance

As an ISO‑nominal insert, compatibility with holders is determined by shape, relief angle, tolerance class, fastening method, size and thickness. Select a holder that matches the TNMG220408 designation and the intended depth of cut for optimal heat dissipation and rigidity. The grade is chosen for its resistance to edge breakdown in applications with elevated chipping risk, making it especially suitable for interrupted turning or batches with variable material quality.

FAQ

What materials is this insert suited for? The TNMG220408 AH6235 insert is designed primarily for stainless steel applications and for situations with interrupted cuts where increased chipping risk is present.

How does the AH6235 grade affect performance? AH6235 is a tougher, PVD‑coated carbide grade that improves resistance to edge breakdown and offers reliable wear behaviour in demanding turning operations.

Is the insert compatible with standard TNMG holders? Yes, the insert follows ISO‑standard TNMG dimensions; compatibility depends on matching holder form, relief angle, tolerance and fastening method.

How many usable cutting edges are available per insert? The triangular, double‑sided design provides multiple indexable edges, allowing several repositions before replacement and extending overall edge life.
