DNMG150408 GT9530 ISO indexable turning insert for turning — Tungaloy

The DNMG150408 GT9530 is an ISO‑normed indexable turning insert designed for external and internal turning, providing a wear‑resistant coated cermet grade optimised for finishing and light universal cuts.

• Coated cermet grade GT9530 for finishing
• ISO DNMG 150408 rhombic insert, 55° cutting angle
• 0° rake and cylindrical mounting hole for stability
• 0.8 mm nose radius for consistent surface finish

Precision finishing and extended tool life for steel turning

The GT9530 coated cermet combines a fine ceramic matrix with a metallic binder to deliver excellent wear resistance and a superior surface finish when machining steel. In stable machining conditions the material composition reduces flank wear and helps achieve consistent part quality over longer tool life, which in turn lowers running costs and reduces unplanned stoppages. This makes the grade particularly suitable where a high‑quality finish and predictable performance are priorities.

Secure seating and predictable cutting geometry save setup time

Delivered in the ISO DNMG form, the insert’s rhombic geometry and 55° cutting angle ensure predictable engagement with the workpiece. The cylindrical hole and the specified plate thickness (4.76 mm) provide accurate centring and repeatable clamping in compatible external holders and boring bars; compatibility depends on holder form, clearance angle, tolerance class, fastening and size. The 0° rake gives a neutral cutting action that improves stability during finishing cuts and is especially beneficial when rigidity of the tool setup is the limiting factor.

Reproducible chip control and economical edge utilisation

The double‑sided chipbreaker design offers controlled chip formation and the option to present a fresh cutting edge after indexing, supporting continuous production and predictable change intervals. Combined with the 0.8 mm nose radius, this results in uniform surface quality and reduces the need for secondary finishing. The coated cermet grade is aimed at light universal to finishing operations in steel where stable conditions prevail; selecting the matching chipbreaker and holder according to workpiece material and process stability will maximise productivity.

Clear application scope and selection guidance

Designed primarily for turning of steel, the insert is suitable for both external and internal operations where a good surface finish and longer life under steady cutting conditions are required. When defining a machining strategy, pair the insert with a matching external holder or boring bar and a suitable clamp set and screws to complete the system. For mixed‑operation shops, consider toolholder rigidity and process stability first; the GT9530 grade rewards stable setups by delivering consistent results and less frequent edge changes.

FAQ

Which materials is this insert intended for?
The DNMG150408 GT9530 is specified mainly for machining steel, providing good surface finish and extended life in stable turning conditions.

Is the insert indexable and how does the chipbreaker help?
The insert features a double‑sided chipbreaker, allowing reindexing to present additional cutting edges and delivering reproducible chip control for finishing operations.

How does the cylindrical hole benefit the setup?
A cylindrical mounting hole aids precise centring and secure clamping in compatible holders, improving repeatability and reducing setup variation.

What holder type is required for this DNMG insert?
Compatible external holders or boring bars must match the ISO DNMG form, clearance angle, tolerance class, fastening method, size and thickness to ensure correct seating and cutting geometry.

For which turning operations is this grade most suitable?
The GT9530 grade is optimised for finishing and light universal turning in steel, where a balance of surface quality and tool life is required.
