VCMT 160404 AH8015 — ISO VCMT turning insert for general turning (Tungaloy)

VCMT160404‑TM AH8015 is an ISO‑format indexable turning insert optimised for general external and internal turning, designed to machine heat‑resistant alloys with a balanced combination of wear resistance and edge stability.

• PVD‑coated carbide AH8015 for heat‑resistant alloys
• TM chipbreaker for controlled chip formation
• ISO format VCMT 160404 for standard toolholders
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance for difficult alloys

The PVD‑coated carbide substrate in this grade delivers a durable cutting edge that is particularly suited to machining heat‑resistant alloys. The chosen microstructure of the AH8015 grade offers a compromise between wear resistance and edge toughness, which translates into longer intervals between indexings and a more predictable tool life. For routine and mixed‑batch turning operations, this balance reduces unplanned stops and supports steady production rates.

Predictable fit and repeatability in ISO tooling systems

As an ISO‑format rhombic insert with a 16 mm cutting‑edge length and a plate thickness of 4.76 mm, the insert is designed for straightforward integration into standard VCMT holders. Key geometric values such as the 0.4 mm corner radius, 7° clearance, and the primary 35° orientation ensure repeatable seating and cutting geometry when the holder, shim and clamp match the ISO parameters. The cylindrical hole with 40°–60° countersink provides secure clamping and reliable repeatability for both internal and external turning setups.

Improved process reliability through chip control and system design

The TM chipbreaker is engineered to produce short, controllable chips across a range of feeds and depths of cut, improving swarf evacuation and reducing the likelihood of built‑up edge. In practice, pairing this insert with a suitable holder, underlay/shim and correct clamping hardware forms a complete system that supports consistent surface finish and dimensional stability. The system approach—insert, holder, shim, clamp and spare screws—reduces setup time and contributes to lower overall cycle times while maintaining machining quality.

FAQ

What materials are suitable for this insert?
The VCMT160404‑TM AH8015 insert (Tungaloy indexable turning insert, SKU TUN6825803 / 6825803‑Tungaloy) is primarily intended for machining heat‑resistant alloys and offers a balance between wear resistance and edge stability for general turning work.

Which toolholders are compatible with this format?
Compatibility is determined by form, clearance, tolerance class, fastening, size and thickness; the VCMT 160404 format is compatible with standard VCMT holders that accept ISO‑designated rhombic inserts.

Which dimensions should be checked before procurement?
Verify the plate size (16 mm), plate thickness (4.76 mm), corner radius (0.4 mm), clearance angle (7°) and the ISO code (160404) to ensure correct fit and repeatability.

How does the TM chipbreaker affect machining?
The TM chipbreaker promotes short, controlled chip formation which aids swarf handling, contributes to a consistent surface finish and lowers the risk of built‑up edge in many turning operations.

Is AH8015 a universal grade for turning?
AH8015 is a versatile PVD‑coated carbide grade selected as a first choice for general machining of heat‑resistant alloys, offering a practical compromise between tool life and edge stability.
