TPMT130308-PSS T9225 – ISO turning insert for external and internal turning by Tungaloy

The TPMT130308-PSS T9225 is an ISO‑standard triangular indexable insert designed for turning operations where robustness and reliable chip control are required

• CVD-coated carbide for robust wear resistance
• Triangular 60° form with 0.8 mm corner radius
• 11° clearance angle for stable engagement

Consistent performance with a universal, robust grade

The main advantage of the supplied grade is its CVD-coated carbide construction, identified as T9225, which combines wear resistance with sufficient toughness. This makes the insert particularly suited to medium to heavy steel machining where cutting conditions can vary or include slight interruptions. The coated substrate reduces flank wear and helps maintain dimensional stability over longer tool life, translating into fewer tool changes and more predictable machining cycles.

Geometry engineered for process stability and surface quality

The triangular plate with a 60° included angle and a 0.8 mm corner radius provides a balance between strength and finish. The 11° clearance angle minimises rubbing and supports consistent chip flow when paired with the PSS chipbreaker, which is matched to the grade for effective chip control. Together, these features contribute to stable cutting forces, reduced vibration and improved surface integrity on shafts and bores during external and internal turning.

Practical compatibility and assembly guidance

This ISO plate is supplied in the TPMT130308 format and is designed for use with matching external holders or boring bars; compatibility depends on form, clearance angle, tolerance class, clamping and thickness. The insert includes a cylindrical hole with a single‑side countersink (40°–60°) to suit standard clamping sets and replacement screws. Selecting the appropriate chipbreaker and grade for the workpiece material and the chosen machining strategy ensures productive and repeatable performance.

FAQ

What materials is this insert intended for? The Tungaloy TPMT130308-PSS T9225 insert is a universal, robust grade intended primarily for medium to heavy steel machining where variable engagement or slightly interrupted cuts occur.

How does the PSS chipbreaker affect machining? The PSS chipbreaker on this ISO insert promotes controlled chip formation and evacuation; combined with the T9225 grade, it improves process stability and reduces the risk of built-up edge during turning.

What holder characteristics are required for compatibility? Compatibility is determined by the form, clearance angle, tolerance class, clamping method, size and thickness of the insert; matching the TPMT130308 format with a suitable external holder or boring bar and clamping kit is recommended.

Is this insert suitable for internal boring operations? Yes, the triangular TPMT130308-PSS insert is suitable for both external turning and internal boring when installed in an appropriate boring bar and clamped according to ISO specifications.

What are the key geometry values to consider for tool selection? Key values include the 60° included angle, 11° clearance angle and the 0.8 mm corner radius; these influence strength, surface finish and cutting engagement in turning applications.
