DNMG150408 T515 — Tungaloy indexable insert for turning, CVD-coated carbide, 55°

The DNMG150408 T515 Tungaloy insert is an ISO-compliant, rhomboid indexable insert designed for efficient external and internal turning of cast iron components.

• CVD-coated carbide for long life
• Optimised for cast iron machining
• Double-sided chipbreaker design
• Rhomboid 55° geometry for versatile turning
• Cylindrical hole for secure clamping

Productivity gains through a wear-resistant cutting grade

The combination of a CVD-coated carbide substrate and the economic T515 grade is aimed at maximising tool life while maintaining stable cutting conditions when machining cast iron. This delivers measurable improvements in cycle time and downtime reduction, as the wear behaviour is controlled and predictable. The choice of a robust, coated cemented carbide helps to reduce the frequency of insert changes and supports higher average material removal rates without sacrificing surface quality.

Secure clamping and ISO compatibility for predictable set-up

Thanks to the ISO-compliant geometry and a cylindrical hole for fixation, the insert integrates cleanly into standard turning toolholders; compatibility depends on form, clearance angle, tolerance class, attachment method, size and thickness. The rhomboid shape with a 55° approach angle and a plate thickness of 4.76 mm ensures a stable seat and repeatable positioning, which is essential for batch production or serial workflows where consistent results are required.

Improved chip control and versatile cutting performance

The double-sided chipbreaker arrangement contributes to controlled chip formation across a range of cutting parameters, making the insert suitable for interrupted cuts or varied feed rates. The 0° clearance helps maintain positive contact in many turning set-ups, while the 0.8 mm corner radius provides a favourable balance between edge strength and achievable surface finish. These features combine to lower scrap rates and reduce secondary finishing on turned cast-iron parts.

System approach and practical application guidance

Designed as part of an ISO indexable insert system, the component functions within a set-up that includes the insert, a matching external holder or boring bar, a shim/clamping kit and replacement screws. For external and internal turning, select the chipbreaker and grade according to workpiece stability, interruption of cut and the desired cutting speed to exploit the economic potential of the T515 grade. The insert’s rhomboid format and central hole simplify indexing and replacement, supporting continuous machining with minimal set-up times.

FAQ

What materials is this insert recommended for?
The DNMG150408 T515 insert is optimised for machining cast iron; the CVD-coated carbide grade provides stable performance when turning iron-based workpieces.

How many cutting edges are available per insert?
The double-sided design offers two usable cutting edges per indexed position on the DNMG150408 T515 Tungaloy indexable insert, enabling economical edge utilisation.

Which holders are compatible with this insert?
Compatibility is determined by the holder’s form, clearance angle, tolerance class, attachment method, size and thickness; use holders rated for ISO rhomboid DNMG inserts to ensure correct seating.

What benefits does the CVD coating provide?
The CVD-coated carbide on this Tungaloy grade improves wear resistance and thermal stability, extending tool life and supporting consistent machining parameters on cast iron.

Is the insert suitable for interrupted cuts?
Yes, the chipbreaker geometry and robust carbide substrate of the DNMG150408 T515 support interrupted cutting conditions when the appropriate feed and speed are selected.
