DNMG150408 GT9530 Tungaloy indexable turning insert for turning (55° rhombic)

A DNMG150408 GT9530 indexable insert engineered for finishing and light universal turning of steel, designed for stable setups and extended tool life

• Coated cermet grade GT9530 for wear resistance
• 55° rhombic geometry for stable cutting
• 0.8 mm nose radius for fine surface finish
• Double-sided insert with cylindrical hole for secure clamping

Longer tool life and improved surface quality for finishing

The coated cermet composition of this indexable insert is optimised for wear-resistant finishing and light universal turning of steel where surface integrity and tool life are priorities. The selected grade, GT9530, balances toughness and abrasion resistance to maintain a consistent cutting edge in stable conditions, reducing the frequency of tool changes. By choosing a cermet-based grade rather than a conventional carbide for finishing cuts, shops can reliably achieve improved part finish and extended edge stability without sacrificing process efficiency.

Stable geometry and secure clamping reduce vibration and scrap

With an ISO-conformant rhombic form and a 55° lead angle, the insert provides a predictable cutting direction that benefits both external and internal turning operations. The double-sided design and cylindrical hole arrangement permit safe indexing and quick orientation changes, while the 0.8 mm nose radius supports consistent profile control and surface quality. Compatibility with a matching holder is determined by form, clearance angle, tolerance class, fastening, size and thickness, ensuring a secure fit and minimised chatter when paired with the correct tooling system.

Practical workflow advantages that support productivity

The insert is intended as part of a complete system — an ISO insert, a suitable external holder or boring bar, a backing/clamping kit and replacement screws — so that spindle time is maximised and set-up is repeatable. The integrated chipbreaker design suits finishing to light roughing tasks depending on material and machine stability, which simplifies tool assortment decisions.

FAQ

What materials is this insert suitable for?
The DNMG150408 GT9530 insert is a coated cermet grade intended primarily for finishing to light universal turning of steel, providing improved surface quality and longer life under stable machining conditions.

Is the insert indexable on both sides?
Yes. The DNMG150408 GT9530 Tungaloy indexable insert (SKU 6998074-Tungaloy) is double-sided, allowing rotation to a fresh cutting edge and helping to extend the usable life of each insert.

Which holder type is required for this insert?
Compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness; the insert fits standard ISO holders designed for DNMG150408 geometry and 4.76 mm thickness.

What surface finish can be achieved with this insert?
Thanks to the 0.8 mm nose radius and the GT9530 coated cermet grade, the insert supports fine surface finishes when used in finishing operations with stable tool setups.

Can this insert be used for internal turning?
Yes. The geometry and chipbreaker design make it suitable for both external and internal turning applications when matched with an appropriate boring bar and stable conditions.
