TPMT110208 AH6225 triangular ISO turning insert for external and internal turning — Tungaloy

The TPMT110208-PS AH6225 is an ISO triangular turning insert designed for external and internal turning operations, optimised for rostfreier Stahl and medium-duty applications.

• PVD-coated carbide for rostfreier Stahl
• 0.8 mm corner radius for robust cutting
• Cylindrical hole with 40°–60° countersink
• ISO triangular form, 11° clearance

Reliable performance for rostfreier Stahl and mixed conditions

An insert designed to balance a sharp cutting edge with robustness: the PVD-coated carbide grade AH6225 provides enhanced wear resistance while maintaining the edge geometry needed for rostfreier Stahl. The combination of a 0.8 mm corner radius and a controlled edge preparation reduces the risk of edge chipping during interrupted cuts and variable feed conditions, delivering stable cutting and predictable tool life. This translates into fewer tool changes, higher machine uptime and improved process repeatability on the shop floor.

Secure clamping and simple holder compatibility

The triangular plate with a cylindrical hole and one-sided countersink (40°–60°) ensures reliable clamping in standard ISO holders. Compatibility is governed by plate form, clearance angle, tolerance class, clamping and plate thickness — all critical for safe seating and repeatable positioning. The 11° clearance minimises rubbing at the flank, while the 2.38 mm plate thickness and 11 mm inscribed circle provide mechanical stability under axial and radial loads, making the insert suitable for both external and internal turning when paired with the appropriate holder and clamping set.

Grade AH6225: consistent chip control and edge life

The AH6225 grade is a PVD-coated solution developed as a universal option for rostfreier Stahl, offering a sharp but stable cutting edge for medium machining parameters. The PS chipbreaker is designed to produce controllable chips across a range of feeds and depths, reducing manual intervention and improving surface finish. For operators, this means more consistent component quality and a reduction in process variability when machining complex geometries or mixed-batch production.

Practical selection and process benefits

Selecting this ISO triangular insert reduces setup complexity: use the ISO designation to match holders, and choose chipbreaker and grade according to material and stability of the setup. The design supports efficient chip evacuation and repeatable seating, which together enhance cycle-time reliability. In applications where rostfreier Stahl is predominant, the balanced edge and coating system minimise built-up edge and thermal wear, helping to maintain tolerances and surface integrity over longer runs.

FAQ

What materials is this insert suited for? The TPMT110208-PS AH6225 is optimised for rostfreier Stahl and performs reliably across many medium-duty turning tasks on similar alloys.

Which chipbreaker is fitted and what does it do? This insert uses the PS chipbreaker, which promotes controlled chip formation across a range of feeds and depths, aiding surface finish and evacuation.

How is holder compatibility determined? Compatibility depends on plate form, clearance angle, tolerance class, clamping method, size and thickness; matching these parameters ensures correct seating of the insert.

What are the key dimensional values to check when replacing an insert? Important values include the inscribed circle (11 mm), plate thickness (2.38 mm), corner radius (0.8 mm), clearance angle (11°) and included angle (60°).

Can this insert be used for both external and internal turning? Yes, the design and dimensions make it suitable for both external and internal turning when used with an appropriate holder and clamping set.
