TPMT 110308 GH730 — ISO turning insert for general turning (Tungaloy)

TPMT 110308-PS GH730 is an ISO‑standard triangular indexable insert designed for a wide range of turning tasks, offering a balanced combination of wear resistance, toughness and edge stability.

• ISO triangular insert, 60° form
• GH730 cemented carbide grade
• PS chipbreaker for stable cutting
• 0.8 mm corner radius, with centre hole

Reliable productivity through grade and geometry

The TPMT110308-PS GH730 indexable insert combines an ISO‑standard triangular geometry with the GH730 cemented carbide grade and a PS chipbreaker to deliver consistent metal removal rates in routine turning. The design concentrates on repeatable performance: the 60° point angle and centre hole with a single‑side countersink provide positive mechanical clamping and precise seating in compatible holders. For production environments where predictable tool life and minimal set‑up time matter, this insert reduces downtime and supports steady cycle times.

Durability and cutting-edge stability for tougher cycles

The GH730 grade is selected to balance wear resistance and toughness, extending edge life without compromising reliability under varied cutting conditions. This results in fewer indexings and lower tool consumption over batches, improving cost‑efficiency. The PS chipbreaker is engineered to control chip formation for standard turning operations, promoting stable chip flow and reduced vibration. Together these features maintain surface quality and help meet dimensional tolerances more consistently.

Compatibility and handling made clear

Compatibility with a clamping system depends on the insert’s form, 11° relief, tolerance class, fixing method, size and 3.18 mm thickness. The TPMT shape code (ISO 110308) and the centre hole with cylindrical bore plus one‑sided countersink (40°–60°) are decisive for correct mounting. The 0.8 mm corner radius affects both strength of the cutting edge and achievable radii on finished parts; select the radius based on the required surface finish and cutting loads. When matching to a holder, confirm that the seat geometry and screw system correspond to the ISO specification to ensure secure fixation.

Practical use and workshop advantages

Designed for both external and internal turning, this insert is intended to be indexed or replaced rather than reconditioned; rapid replacement minimises machine downtime. The standardised ISO format simplifies inventory management and cross‑reference with compatible holders. Stored correctly and used with the appropriate cutting parameters, the insert consistently delivers good edge stability and predictable wear behaviour. The combination of an ISO form, cemented carbide composition and a controlled chipbreaker supports everyday workshop productivity while maintaining surface integrity.

FAQ

What applications is this insert intended for?
The TPMT110308-PS GH730 is designed for general turning applications, suitable for external and internal turning where an ISO triangular insert with PS chip control is appropriate.

How is compatibility with a holder determined?
Compatibility depends on the insert form, the 11° relief, tolerance class, fixing method, size and thickness; ensure the holder matches the ISO 110308 seat and the centre‑hole countersink arrangement.

What advantages does the GH730 grade provide?
The GH730 grade balances wear resistance, toughness and edge stability to extend tool life while maintaining cutting performance across typical turning conditions.

What does the PS chipbreaker do in practice?
The PS chipbreaker promotes controlled chip formation for stable evacuation during turning, reducing vibration and improving surface finish in many routine operations.

Is the insert regrindable?
These indexable inserts are designed for indexing or replacement; when the cutting edges are worn, replacement is the standard practice to restore full performance.
