TPMT 090204 GH730 ISO turning insert — triangular 60°, 0.4 mm radius — Tungaloy

The TPMT090204 is a triangular ISO turning insert designed for general external and internal turning operations, offering a compact geometry and a one-sided chipbreaker for predictable chip formation.

• ISO triangular insert, 60° geometry
• GH730 grade for wear resistance
• 0.4 mm corner radius for fine finishing
• Cylindrical hole with 40°–60° countersink

Consistent chip control from matched geometry and grade

The triangular, ISO‑standard shape combined with a dedicated chipbreaker ensures reproducible chip formation during both light finishing and moderate roughing cycles. The combination of a 60° cutting angle and an 11° clearance contributes to stable cutting forces and predictable tool life. These geometric choices reduce vibration and support consistent surface quality, while the single‑sided chipbreaker simplifies selection for standard turning tasks.

Grade selection that balances wear resistance and edge stability

The insert’s GH730 grade is engineered to deliver a compromise between hardness and toughness, which extends tool life under variable cutting conditions. As a tungsten carbide‑based product with an optimised microstructure, the grade sustains a sharp cutting edge and resists flank wear during continuous production runs, supporting higher productivity and fewer index changes.

Clear mounting features for reliable clamping

Mounting and clamping compatibility are defined by the insert’s form, tolerance class, fixing method and thickness. The plate features a cylindrical hole with a one‑sided countersink (40°–60°) that fits a wide range of ISO‑compatible toolholders, enabling fast and secure indexing. The presence of the hole and the standardised profile simplifies integration into existing tooling systems and reduces downtime during tool changes.

Small radius and thin section for refined surface finishes

With a 0.4 mm corner radius and a plate thickness of 2.38 mm, the insert supports fine finishing operations where surface integrity matters. The modest radius achieves a balance between edge strength and the ability to produce tight contour detail, while the slim section assists in limiting cutting forces on slender workpieces or when using extended holder overhangs.

Durable construction for stable production cycles

Produced from high‑quality tungsten carbide, the insert resists chipping and abrasive wear under normal turning conditions, contributing to longer intervals between indexing. The robust substrate and grade selection are aimed at reducing unexpected tool changes, allowing for more predictable planning of maintenance and tool inventory in the workshop.

Practical guidance for selecting the right configuration

For most standard turning tasks, choose holders that match the TPMT form and observe the specified clearance and tolerance classes; pairing the insert with the correct holder and clamp ensures optimal performance. For complex materials or specialised cycles, consult technical data sheets or ask Metav Werkzeuge for advice on geometry and grade combinations to match the application.

FAQ

What turning operations is this insert intended for?
The Tungaloy TPMT090204 GH730 insert is intended for external and internal turning, offering a balanced geometry for both finishing and moderate roughing.

How does the GH730 grade affect performance?
The GH730 grade provides a mix of wear resistance and edge stability, helping the insert maintain form and reduce flank wear during continuous machining.

Which holder features are required for safe clamping?
Clamping compatibility depends on form, clearance angle, tolerance class, fixing method, size and thickness; the insert’s cylindrical hole with countersink matches standard ISO holders.

What mounting details should be noted before ordering?
Note the plate thickness of 2.38 mm, the triangular form (size 09) and the cylindrical hole with a 40°–60° countersink when selecting clamping sets and replacement screws.

How many usable cutting edges does the triangular insert offer?
The triangular plate provides three indexable cutting edges, allowing economical rotation when a cutting edge becomes worn.
