TPMT090204 AH6225 Tungaloy insert — ISO triangular turning insert for turning

TPMT090204 AH6225 Tungaloy insert designed as an ISO-standard triangular turning insert for external and internal turning of stainless steels, offering a sharp yet stable cutting edge for medium machining conditions

• ISO triangular insert, 60° cutting angle
• PVD-coated carbide AH6225 for stainless steels
• 11° clearance and 0.4 mm corner radius
• Cylindrical hole with single-sided countersink

Engineered for consistent metal removal and predictable tool life

The PVD-coated AH6225 grade provides a well-balanced combination of edge sharpness and stability, specifically formulated for stainless steels under varying cutting conditions. As an ISO-series insert, its geometry and tolerance range deliver predictable seating and repeatable performance when paired with a compatible holder. The proven substrate and coating support stable chip formation and reduced flank wear during medium cutting operations, which in turn helps to maintain component quality and minimise unscheduled tool changes.

Precision geometry and secure clamping reduce vibration and improve surface finish

A triangular plate with a 60° cutting angle and a 0.4 mm corner radius gives a good compromise between strength and finish. The 11° clearance angle and a plate thickness of 2.38 mm ensure stable support in the pocket, while the cylindrical hole with a single-sided countersink (40°–60°) provides reliable mechanical clamping and repeatable positioning. These geometric details, combined with a one-sided chipbreaker, contribute to steady cutting forces, improved surface quality and reduced tendency for chatter in both external and internal turning tasks.

Proven coating and grade for productive machining and process security

The combination of a PVD coating on a hardmetal substrate yields extended edge life and consistent wear behaviour, especially when machining rostfreie Stähle. The AH6225 grade is a universal choice for a variety of stainless steel alloys, designed to keep a sharp cutting edge while resisting abrasion and built-up edge under changing conditions. Selecting the correct chipbreaker and matching the insert to the workpiece stability and feed strategy enables cost-effective production with fewer tool changes and predictable component tolerances. The ISO-system approach also simplifies inventory management and reduces setup risk.

Practical system considerations and compatibility guidance

Compatibility with the clamping system is defined by the insert form, clearance angle, tolerance class, fixation method, size and thickness; the cutting system typically comprises the ISO insert, a matching external holder or boring bar, a shim/underplate and clamping screws. When integrating this insert into a process, ensure the holder pocket accepts an ISO triangular plate with the specified 090204 designation and that the selected clamping screws and shims match the insert's hole and countersink geometry. Proper seating and clamp torque are decisive for achieving repeatable cutting performance and safe operation.

FAQ

Which materials is this insert best suited for? This TPMT090204 AH6225 Tungaloy insert is primarily specified for machining stainless steels, offering a balance of edge sharpness and wear resistance suitable for medium cutting operations.

How does the AH6225 grade behave under variable cutting conditions? The AH6225 grade on the TPMT090204 insert maintains a sharp, stable cutting edge and supports consistent chip formation across changing temperatures and feeds, improving process reliability.

What pocket and clamping features are required for correct seating? A pocket that accepts ISO triangular inserts with the 090204 designation and a cylindrical hole with single-sided countersink is required; the TPMT090204 must be clamped securely to ensure repeatable positioning.

Can this insert be used for both external and internal turning? Yes — the triangular geometry and the one-sided chipbreaker make the TPMT090204 AH6225 insert suitable for both external and internal turning, provided the holder and stability conditions match the machining task.

What edge preparation is offered and which corner radius suits semi-finish work? The TPMT090204 is supplied with a 0.4 mm corner radius, which is appropriate for semi-finishing and provides a compromise between edge strength and surface quality.
