TCMT 110204 AH6225 — Turning insert, PVD-coated carbide, Tungaloy

TCMT 110204 AH6225 is an ISO-designated triangular indexable insert for external and internal turning, engineered for reliable performance on stainless steels.

• TCMT110204 triangular insert, 7° clearance
• PVD-coated carbide grade AH6225
• One-sided chipbreaker, cylindrical hole with countersink
• Sharp yet stable edge for stainless steel

Consistent edge stability for medium turning operations

The PVD-coated carbide grade AH6225 provides a balance between sharpness and edge robustness, designed for variable machining conditions. This combination reduces built-up edge and supports steady tool life during cyclic and interrupted cuts. By prioritising a stable cutting geometry, the insert enables improved surface finish while maintaining acceptable wear rates, making it suitable for batch production where repeatable performance and predictable regrinding intervals are required. The coating enhances wear resistance and thermal stability, which translates into fewer unscheduled tool changes and better process reliability.

ISO compatibility and straightforward mounting reduce setup time

As an ISO turning insert in triangular form, the TCMT110204 fits established holder systems where form, clearance, tolerance class, fixing and thickness determine compatibility. The 7° clearance and 2.38 mm thickness are matched to common external and internal turning holders, and the presence of a cylindrical hole with a one-sided countersink (40°–60°) facilitates secure clamping and repeatable indexing. These characteristics simplify inventory management and reduce setup complexity across multiple lathes, supporting faster changeovers and consistent clamping accuracy in production environments.

Controlled chip formation and application suitability

The single-sided chipbreaker design focuses on predictable chip control when machining stainless steel, particularly under medium cutting conditions and varying stability. Proper selection of feed and depth of cut, together with this chipbreaker geometry, helps avoid long, stringy chips and supports uninterrupted operation. For a wide range of turning tasks—both external profiling and bore finishing—the insert’s configuration balances cutting efficiency and process safety, offering a pragmatic solution for workshop and production settings that prioritise throughput without compromising surface quality.

System clarity and practical benefits for workshop use

The TCMT110204 insert forms part of a standard system: an ISO indexable insert, a compatible external holder or boring bar, an appropriate shim/clamp set and replacement fastening screws. Compatibility depends on matching the insert form, clearance angle, tolerance class, fixing method, size and thickness. This clarity allows production planners and tooling engineers to integrate the insert into existing toolholders with minimal adaptation, supporting streamlined procurement and predictable tool consumption. Where medium-duty stainless-steel turning is required, this insert offers a pragmatic mix of performance and availability.

FAQ

Which materials is this insert best suited for?
The TCMT110204 AH6225 insert is optimised for stainless steel machining; the AH6225 grade and PVD coating deliver a balance of edge sharpness and wear resistance suitable for medium cutting conditions.

How does the PVD coating benefit tool life?
A PVD-coated carbide insert reduces abrasive wear and improves thermal resistance, which helps maintain a sharper cutting edge for longer during cyclic turning tasks with the TCMT110204 AH6225.

What does the hole and countersink geometry mean for clamping?
The cylindrical hole with a one-sided countersink (40°–60°) provides secure and repeatable clamping in ISO-compatible holders, ensuring stable positioning and reliable indexing of the insert.

For which turning operations is the insert recommended?
This triangular indexable insert is designed for both external and internal turning operations; the single-sided chipbreaker supports controlled chip formation in a variety of machining setups.

Is a 0.4 mm corner radius suitable for profile work?
A 0.4 mm corner radius offers a compromise between edge strength and the ability to maintain detail on profiles; it is appropriate for many finishing and medium-roughing tasks where controlled edge contact is required.
