DNMG 150404 T515 Tungaloy indexable turning insert – CVD‑coated carbide for cast iron, 55° rhombic

DNMG150404 T515 is an ISO‑compatible indexable insert designed for external and internal turning in industrial machining applications, optimised for the economical machining of cast iron.

• CVD‑coated carbide grade T515
• Engineered for cast iron machining
• ISO DNMG 150404 rhombic 55° geometry
• Double‑sided insert with cylindrical hole
• 0.4 mm corner radius, 4.76 mm thickness

Predictable performance and lower machining costs

The CVD‑coated carbide designation T515 provides a balance of wear resistance and toughness that suits the economic removal of cast iron components. The coating reduces flank wear and extends usable edge life, which translates into fewer indexings and lower tooling expenditure per component. Consistent edge behaviour reduces unplanned downtime and helps maintain a steady production throughput, supporting measurable productivity improvements.

Geometry that supports versatile turning and secure clamping

The rhombic DNMG form with a 55° lead angle offers versatility for both external and internal operations, while the insert’s 0° relief and 0.4 mm corner radius deliver a defined cutting edge for medium‑finish turning. The double‑sided design and cylindrical locating hole provide two usable edges per side and reliable seating in compatible holders; compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness. This makes tool changes predictable and economical in assembly lines or toolrooms.

Improved chip control and surface quality

A double‑sided chipbreaker combined with the T515 grade facilitates stable chip formation when machining grey and nodular cast irons; the chipformer geometry reduces entanglement and assists coolant flow near the cutting zone. Stable chips and reduced built‑up edge contribute to a more consistent surface finish, lowering downstream processes such as manual deburring or polishing. For interrupted cuts, the grade’s toughness mitigates chipping when the machining setup provides sufficient rigidity.

System integration and shopfloor benefits

The insert is intended to be used as part of a system: indexable insert, compatible external holder or boring bar, shim/clamp set and replacement screws. This modular approach enables fast replacement, straightforward inventory control and predictable process behaviour across different machines. Clear part standardisation simplifies procurement and tooling strategies, supporting lean manufacturing goals and easier qualification for batch production.

FAQ

What materials is this insert suitable for machining?
The DNMG150404 T515 insert is formulated for the economical machining of cast iron; the T515 CVD‑coated carbide grade provides wear resistance and toughness for grey and nodular cast irons.

How many usable edges does the insert provide?
The rhombic DNMG geometry with double‑sided chipbreaker supplies multiple usable cutting edges; the design allows indexing to present a fresh edge when required.

Which holder types are compatible with this insert?
Compatibility depends on the holder’s form, clearance angle, tolerance class, fastening method, size and thickness; the insert is intended for ISO‑compatible turning holders and boring bars.

Is the insert suitable for interrupted cuts?
Yes—when the machining setup offers sufficient stability, the T515 grade’s toughness supports interrupted cutting, reducing the risk of edge chipping.

What advantages does the T515 CVD coating bring?
The CVD coating on the T515 grade enhances wear resistance and heat protection, extending edge life and promoting consistent surface finish in cast iron turning operations.
