TCMT 16T308 AH8015 — Turning insert, PVD‑coated carbide by Tungaloy

A TCMT 16T308 AH8015 ISO triangular turning insert designed for external and internal turning of heat‑resistant alloys in ISO‑standard tool systems

• PVD-coated carbide AH8015 for heat resistance
• ISO triangular shape with 60° included angle
• Cylindrical hole with 40°–60° countersink
• Balanced wear resistance and edge stability

High‑temperature performance and coating benefits for reliable cutting

The PVD‑coated AH8015 grade combines wear resistance with edge stability to suit general machining of heat‑resistant alloys. The PVD coating reduces chemical wear at elevated temperatures and helps maintain sharpness over longer tool life, which increases process stability in demanding turning operations. For shops prioritising consistent component tolerances, this balanced grade offers a pragmatic trade‑off between toughness and hardness that supports repeatable surface finish and dimensional control.

Geometry and chip control that simplify setup and increase uptime

The triangular ISO 60° geometry with a 0.8 mm corner radius and 7° relief provides a predictable cutting edge for external and internal turning cycles. The one‑sided chipbreaker promotes controlled chip formation when machining alloys with variable machinability, while the cylindrical hole with single‑side countersink (40°–60°) enables rigid, repeatable clamping in compatible ISO holders. Clearances and tolerances are determined by insert form, attachment method and thickness; the 3.97 mm thickness contributes to stiffness, reducing vibration in medium‑duty turning tasks.

System integration and application guidance for efficient production

As part of the ISO indexable insert family, the insert integrates with standard external holders, boring bars and clamping sets to form a complete turning system. Selection of the chipbreaker and the AH8015 grade should be matched to workpiece material and cutting parameters: choose the noted grade for heat‑resistant alloys where a combination of flank wear resistance and edge stability is required. Indexable inserts such as this support fast re‑indexing, minimise tool change time and help maintain throughput in batch production. For applications with different material demands, consider alternative chipformers or grades within the ISO series to optimise life and surface finish.

FAQ

What materials is this insert suited for?
The TCMT 16T308 AH8015 insert is primarily specified for machining heat‑resistant alloys, where the AH8015 grade balances wear resistance and edge stability for reliable performance.

Can the insert be used for internal and external turning?
Yes; the triangular ISO geometry and the available holders make the insert suitable for both external and internal turning operations when mounted in compatible toolholders.

How does the PVD coating influence tool life?
The PVD coating on the AH8015 grade reduces chemical wear at elevated temperatures and helps maintain edge integrity, often extending effective tool life under high‑temperature cutting conditions.

What does the hole and countersink specification mean for clamping?
The cylindrical hole with a 40°–60° single‑side countersink provides positive seating and repeatable clamping in standard ISO indexable insert holders, ensuring rigidity and consistent positioning.

Is the 0.8 mm corner radius suitable for finishing operations?
A 0.8 mm corner radius offers a compromise between strength and the ability to achieve good surface finish; for fine finishing you may consider a smaller radius if available and compatible with the holder.
