TPMT110204 GH730 — Tungaloy indexable turning insert (ISO 110204) for turning

The TPMT110204 GH730 is an ISO‑spec triangular indexable insert engineered for external and internal turning, offering a balanced blend of wear resistance and edge stability.

• ISO 110204 triangular insert design
• GH730 grade for enhanced wear resistance
• 0.4 mm corner radius for fine profiling
• Cylindrical hole with countersink for secure clamping

Consistent cutting performance for production turning

The insert is manufactured from cemented carbide and specified in the GH730 grade to combine wear resistance with sufficient toughness for stable cutting edges. As an ISO series item, it supports consistent replacement cycles and predictable tool life, which helps maintain process stability and reduces downtime. The combination of the grade and geometry supports efficient material removal rates while preserving surface finish quality, contributing to improved throughput in repetitive turning operations.

Compatibility and straightforward tool integration

Designed to fit ISO‑specified toolholders, compatibility is determined by form, clearance angle, tolerance class, clamping style, size and thickness. The insert features a cylindrical hole with a one‑sided countersink (40°–60°) to ensure secure clamping and simple mounting into matching holders. The 2.38 mm thickness and triangular shape with a standard 11 mm size enable integration into common external and internal turning tool assemblies used in industry, simplifying stock management and tool change procedures.

Optimised chip control and extended edge life

The single‑sided chipbreaker and the GH730 formulation are selected to manage chips effectively while preserving the cutting edge under varying cutting conditions. The single‑sided chipbreaker supports predictable chip formation, reducing the risk of built‑up edge and improving surface quality. The 0.4 mm corner radius offers a compromise between edge strength and detailability, ideal for finishing passes and light profiling where a defined radius improves component integrity.

Practical handling and recommended applications

With a 11° clearance angle and a 60° wedge angle, the insert suits general turning tasks that require a stable seating and defined cutting geometry. The system approach — insert, matched external holder or boring bar, support pad/clamping set and replacement screws — ensures reproducible clamping forces and repeatable performance. Selection of chipbreaker and grade should be matched to the workpiece material and the rigidity of the setup; smaller radii favour finer contours, while the GH730 grade favours longer edge life under semi‑finishing to finishing conditions.

FAQ

What materials is this insert suited for?
The GH730 grade and the cemented carbide substrate make the TPMT110204 GH730 suitable for a broad range of turning tasks where wear resistance and edge stability are required; the final selection depends on the workpiece material and machining parameters.

How is the insert clamped in the holder?
The insert uses a cylindrical hole with a one‑sided countersink to allow secure clamping in appropriately designed ISO holders and support pads, ensuring repeatable seating and clamping forces for the TPMT110204 GH730.

What does the 0.4 mm corner radius mean for finishing?
A 0.4 mm corner radius increases edge strength while still permitting fine surface profiling, making the insert appropriate for finishing passes where a defined contour is needed.

Can the chipbreaker be used for heavy roughing?
The single‑sided chipbreaker is optimised for controlled chip formation; while suitable for many turning operations, the machining strategy for heavy roughing should consider insert grade, machine rigidity and clamping stability before selecting this insert for high‑stock removal.

How to ensure compatibility with existing toolholders?
Compatibility is determined by insert form, clearance angle, tolerance class, clamping arrangement, size and thickness; match these parameters with holder specifications to confirm fit for the TPMT110204 GH730.
