VNMG 160402 AH120 – VNMG turning insert, PVD-coated carbide, TSF chipbreaker (Tungaloy)

A VNMG160402-TSF AH120 indexable turning insert designed for ISO-standard external and internal turning operations with a rhombic form and cylindrical hole

• ISO-standard rhombic insert 16 mm
• PVD-coated carbide grade AH120
• TSF chipbreaker for stable chips
• 0.2 mm corner radius, 35° geometry

Reliable geometry for repeatable turning results

The rhombic ISO shape and 35° geometry deliver a predictable cutting direction and consistent engagement in both external and internal turning. The combination of a 0.2 mm corner radius and a neutral 0° clearance angle suits light to medium cuts where a sharp cutting edge is required without sacrificing process stability. Such geometry helps to maintain a steady contact zone between insert and workpiece, reducing vibration and improving dimensional consistency during serial production.

Coating and grade: what AH120 brings to the process

The PVD-coated carbide substrate in grade AH120 is formulated for wear resistance and resistance to chipping under interrupted cuts. The PVD layer enhances surface hardness and reduces adhesion of built-up edge on many workpiece materials, while the underlying carbide provides toughness. For operations that require a sharp edge and reliable tool life, this grade offers a balanced performance that supports productivity and reduces unplanned tool changes.

TSF chipbreaker and chip control explained

The TSF chipbreaker is engineered to promote short, controllable chips in a range of cutting conditions. Proper chip control safeguards the workpiece surface and protects tool holders from entanglement or damage, especially in longer turning cycles. In practice, the chipformer design reduces manual intervention and cleaning time, supporting smoother machine throughput and safer production environments.

Compatibility and selection criteria for holders

Compatibility depends on insert form, clearance angle, tolerance class, fastening method, size and thickness. The VNMG designation and ISO series indicate the standardised interface; the rhombic plate with a cylindrical hole fits compatible clamping systems and boring bars designed for inserts of this geometry. When selecting a holder, verify that the insert pocket matches the ISO 160402 profile and that clamping screws and underlays correspond to the insert thickness and hole style to ensure stable seating and repeatable results.

Practical advantages for workshop workflows

Using an indexable insert with a sharp PVD-coated edge reduces regrinding and resharpening effort compared with brazed tools, enabling faster tool changes and predictable replacement intervals. The wear- and chip-resistant properties of the AH120 grade contribute to longer continuous runs and fewer process interruptions. For manufacturers seeking a balance of edge sharpness and process security, this insert supports productive turning across a broad range of components.

FAQ

Which materials can be machined with this insert?
The VNMG160402-TSF AH120 insert from Tungaloy is intended for turning a broad range of materials; the AH120 grade offers wear resistance and chipping protection suitable for many steels and alloyed materials.

How does the TSF chipbreaker assist in production?
The TSF chipbreaker on the VNMG160402-TSF insert shapes chips into short, controllable segments, improving chip evacuation and reducing the risk of entanglement during long turning cycles.

What does the 0.2 mm corner radius affect in practice?
A 0.2 mm corner radius balances edge strength and surface finish; it supports a sharp edge for fine turning while providing enough edge support to resist premature chipping in interrupted cuts.

Is the insert compatible with standard ISO holders?
Yes; the VNMG160402-TSF follows ISO standard designation and is compatible with holders and boring bars that accept rhombic inserts with the corresponding ISO 160402 profile, hole style and clamping arrangement.

What distinguishes the AH120 grade from other carbide grades?
The AH120 PVD-coated carbide grade emphasises wear resistance and edge toughness for turning operations where a sharp cutting edge and process reliability are required, helping to extend tool life in serial production.
