TCMT 110308 AH6225 Turning insert (ISO) by Tungaloy — PVD-coated carbide, 60° triangle

A TCMT110308 AH6225 indexable turning insert intended for external and internal turning, optimised for stainless steels and medium machining conditions

• ISO TCMT 110308 geometry
• PVD-coated carbide substrate
• Suited for stainless steels machining
• Triangular insert with 60° included angle

Reliable performance for stainless-steel turning

The PVD-coated carbide grade AH6225 combines a sharp yet durable cutting edge with resistance to work-hardening typical of stainless steels. This results in a steadier cutting action and reduced tendency to built-up edge, which supports higher process stability in interrupted or variable cutting conditions. The insert’s configuration contributes to predictable tool life and a reproducible surface finish, helping to lower unplanned downtime and improve batch repeatability.

ISO conformity and simple integration into existing tool systems

As an ISO indexable insert in the TCMT110308 format, the part is compatible with holders and boring bars that match its form, 7° clearance and tolerance class. The system build — an ISO insert combined with a suitable external holder or boring bar, plus a matching shim/clamp set and spare screws — simplifies inventory management and shortens changeover times. Clear identification by ISO designation enables rapid selection for both external and internal turning tasks.

Coating, edge geometry and what they mean in practice

The PVD coating enhances wear resistance while maintaining a sharp cutting edge suitable for medium-depth cuts; this supports consistent chip formation even under fluctuating cutting parameters. The 0.8 mm corner radius balances edge strength and surface integrity, making the insert versatile between light finishing and more robust turning passes. The single-sided chipbreaker controls chips effectively in many stainless-steel grades, reducing the need for special chip-handling measures.

Practical benefits for workshop productivity

Using a standardised triangular insert with a 60° included angle and 3.18 mm thickness reduces the number of special tools required on the shop floor and supports quicker set-up routines. The design choices — from the central hole with cylindrical bore and single-sided countersink to the PVD-treated substrate — aim to deliver reproducible clamping and consistent performance across batches. Overall, the combination of geometry and grade supports efficient, repeatable production flows and easier stock-keeping for maintenance teams.

FAQ

What materials is this insert suitable for?
The TCMT110308 AH6225 turning insert from Tungaloy (SKU 6903332-Tungaloy) is optimised for stainless steels, offering good chip control and wear resistance in medium machining.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; the TCMT110308 format follows ISO standards to ensure broad compatibility with matching external holders and boring bars.

How does the PVD coating affect tool life and finish?
The PVD-coated carbide substrate on the Tungaloy AH6225 grade improves wear resistance while maintaining a sharp cutting edge, which supports consistent surface finish and longer life in variable stainless-steel turning.

What is the purpose of the central hole and countersink?
The cylindrical hole with a single-sided countersink (40°–60°) provides secure and repeatable clamping, increasing stability under load and simplifying indexable insert replacement in standard clamping systems.

Which operations is the insert designed for?
This triangular, 60° indexable insert is intended for both external and internal turning operations in medium machining regimes, especially where stable chip formation and reproducible results are required.
