TPMT110208-PSS AH6225 – TPMT 110208 AH6225 turning insert for stainless steel, PVD-coated (Tungaloy)

TPMT110208-PSS AH6225 is an ISO-standard triangular indexable insert engineered for external and internal turning of stainless steels, offering a sharp yet robust cutting edge and a PSS chipbreaker for consistent chip control.

• PVD-coated cemented carbide AH6225
• Optimised for stainless steels and variable conditions
• ISO-standard triangular insert, 11° clearance
• 0.8 mm corner radius for robust edge life

Predictable machining performance for stainless steels

The PVD-coated cemented carbide grade delivers a balance between edge sharpness and stability, designed specifically for processing stainless steel under changing cutting conditions. The combination of the AH6225 grade and the PSS chipbreaker reduces built-up edge and improves chip control, which leads to more consistent component geometry and surface finish during medium-duty turning. The triangular geometry with a 60° included angle provides three usable cutting corners per insert, improving cost efficiency in high-mix production environments.

Designed for reliable assembly and repeatable set-ups

As an ISO-standard insert, compatibility with holders is governed by shape, clearance angle, tolerance class, fastening and plate thickness—values supplied with the component aid rapid verification. The insert features an 11° clearance angle and a cylindrical hole with a one-sided countersink (40°–60°) for secure clamping and repeatable location. With a thickness of 2.38 mm and a standard size designation of 11, the component integrates seamlessly into established tooling systems, reducing set-up time and minimising alignment errors on the shop floor.

Longer edge life and consistent surface quality

The 0.8 mm corner radius increases edge strength without compromising form accuracy, supporting stable cutting at moderate feeds. The PVD layer on the substrate limits adhesive wear and improves thermal resistance, which reduces flank wear in interrupted cuts and under variable cutting conditions. The net effect is fewer insert changes, more stable cycle times and a lower scrap rate—advantages that directly support productivity and cost-efficiency in serial and small-batch turning tasks.

Practical application guidance for turning operations

Intended primarily for turning applications, the insert performs best when matched to a suitable external holder or boring bar and when the chipbreaker and grade are chosen according to the workpiece stability and machining strategy. The design is particularly effective for external and internal turning of stainless steel; choose a clamping system consistent with the insert’s hole and countersink geometry for optimum repeatability. For complex setups or non-standard material mixes, request cutting data from the tool supplier or evaluate trial cuts under production-like conditions.

FAQ

Which materials is this insert best suited for?
The AH6225 grade is formulated as a universal grade for stainless steel machining; the TPMT110208-PSS AH6225 insert performs well with a range of stainless alloys under medium machining conditions.

How does the PSS chipbreaker influence chip formation?
The PSS chipbreaker is designed to produce short, controllable chips when turning stainless steel, helping to prevent tangling and improving evacuation in both external and internal operations.

What are the primary dimensions to check for holder compatibility?
Key dimensions are the insert size (11 mm), thickness (2.38 mm), corner radius (0.8 mm) and the hole/countersink design; these determine fitment and clamping in standard ISO holders.

Can the insert be used for both external and internal turning?
Yes, the insert is intended for both external and internal turning; selection of an appropriate holder and stable set-up is recommended to achieve the best results.

Is regrinding or reconditioning an option for this grade?
Reconditioning depends on the geometry and coating; for guidance on regrinding practices for this AH6225 grade, follow the manufacturer’s specifications and test under controlled conditions.
