TPMT 090204 AH725 indexable turning insert by Tungaloy — PVD‑coated carbide, 60° triangle

The TPMT 090204 AH725 is an ISO‑standard indexable turning insert designed for external and internal turning, offering a universal, chipbreak‑resistant grade optimised for steel and stainless steel.

• ISO‑standard triangular insert
• PVD‑coated AH725 carbide grade
• One‑sided chipbreaker for controlled chips
• Cylindrical hole with 40°–60° countersink

Consistent process security for mixed‑material turning

The AH725 grade is a PVD‑coated carbide formulated for universality and reliable chip formation when machining both steel and stainless steel. The coating improves wear resistance under varying cutting conditions, which supports high process security in mixed‑material production runs. For operations that require stable cutting with smaller tools or frequent material changes, this grade reduces the risk of unexpected edge failure and helps maintain consistent cycle times.

Precision geometry for accurate seating and repeatability

Built to the ISO standard and supplied in a triangular shape with an included angle of 60°, the insert provides reproducible seating in standard holders. The combination of a 0.4 mm corner radius, 11° clearance angle and 2.38 mm thickness ensures a stable cutting edge and predictable deflection behaviour. These geometric parameters contribute directly to repeatable clamping, reduced vibration and improved surface finish—advantages that translate into fewer reworks and more consistent component quality.

Controlled chips and reduced setup time through compatible clamping

The one‑sided chipbreaker design delivers controlled chip flow for common turning tasks, while the cylindrical hole with a 40°–60° countersink supports secure fastening in compatible clamping systems. Holder compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness; therefore, pairing the insert with a matching external holder or boring bar and the correct backing/clamping set is essential for achieving the expected performance. A system approach—insert, holder, backing pad and spare screws—minimises downtime when changing tools.

Practical application guidance for turning operations

Intended for external and internal turning, the insert suits a wide range of tasks where reliability and manageable chip control are priorities. Select the appropriate chipbreaker and grade settings according to workpiece stability and material mix to maximise tool life and productivity. For smaller cutters and demanding process windows the AH725 grade offers a balance between wear resistance and fracture toughness that supports productive machining with consistent results.

FAQ

Is this insert suitable for stainless steel machining? Yes. The TPMT 090204 AH725 insert uses a PVD‑coated AH725 carbide grade designed for reliable performance on stainless steel as well as general steels, offering good chip control and wear resistance.

Which holders are compatible with this triangular insert? Compatibility depends on the holder’s form, clearance angle, tolerance class, fastening and size; the TPMT 090204 AH725 fits ISO‑standard triangular holders for 60° inserts and requires a clamping system that accepts a cylindrical hole with the specified countersink.

What does the 0.4 mm corner radius mean for machining? A 0.4 mm corner radius provides a balance between edge strength and detail: it improves edge robustness and surface finish while remaining suitable for moderate finishing and general turning operations.

Can the insert be used for both internal and external turning? Yes. The insert is specified for external and internal turning; selection of the proper chipbreaker and a suitable boring bar or external holder will determine the final process reliability.

What is included when ordering this article? The offer covers the indexable insert itself (TPMT 090204 AH725). For a complete system, select the appropriate external holder or boring bar, backing pad/clamping set and fasteners according to the holder interface.
