DNMA 150612 T5125 — Turning insert (rhombic, 55°) by Tungaloy

A DNMA 150612 T5125 indexable turning insert designed for ISO‑format turning applications, optimised for interrupted cuts and less stable machining conditions.

• ISO‑compatible rhombic turning insert
• CVD‑coated carbide grade T5125
• 55° geometry with 1.2 mm corner radius
• Suitable for interrupted cuts in cast iron

Stable cutting in interrupted turning for cast iron

The insert delivers predictable edge life thanks to its CVD‑coated carbide composition and the tougher T5125 grade. This combination reduces the risk of premature chipping during interrupted cuts, which makes the tool particularly useful where stability is limited or vibration occurs. The design focuses on maintaining a reliable cutting edge rather than maximising speed, so process reliability is improved and rework is reduced.

Geometry that eases setup and improves accuracy

With a 55° rhombic geometry and a 1.2 mm corner radius, the insert provides a balance between strength and detail on external and internal profiles. The 0° clearance angle and a plate thickness of 6.35 mm support rigid mounting and predictable cutting engagement. These defined dimensions enable faster tool selection and repeatable setup when swapping inserts across compatible ISO holders.

Clear guidance on system compatibility and clamping

The insert follows ISO conventions, so compatibility is determined by holder form, clearance angle, tolerance class, clamping method, size and thickness. The centre cylindrical hole allows secure fastening in many standard clamping systems. When selecting a holder, match the insert’s rhombic form and 15 mm size to the toolholder seat and check the tolerance class to ensure accurate repeatability during index changes.

Practical advantages for production workflows

The absence of an integrated chipbreaker indicates the insert is intended for applications where chip control is achieved by cutting conditions or a suitable holder design. Choosing this grade reduces the likelihood of edge failure in interrupted operations, which supports longer tool life in mixed‑batch production and lowers process interruptions. The insert is best combined with a suitable holder and clamping set to exploit the material coverage and mechanical resilience of the carbide grade.

FAQ

What materials is this insert suitable for? The DNMA 150612 T5125 insert is formulated as a tougher CVD‑coated carbide grade and is particularly recommended for cast iron under interrupted cutting conditions; other materials may be machined depending on cutting data and holder.

How does the 55° geometry affect cutting performance? A 55° rhombic geometry provides a compromise between robustness and access to profile details; the geometry of the DNMA insert helps maintain edge strength while enabling precise external and internal turning.

Is a chipbreaker included with this insert? This insert is supplied without a chipbreaker, so chip control should be achieved by the chosen cutting parameters, the holder geometry or through a matching chip control solution.

Which holders are compatible with this ISO insert? Compatibility depends on holder form, clearance angle, tolerance class, clamping method, size and thickness; the DNMA 150612 format requires a rhombic seat for secure mounting and correct cutting angle.

What is the advantage of the T5125 grade? The T5125 grade combines a tougher substrate with CVD coating to enhance resistance to chipping in interrupted cuts and under less rigid machining conditions, improving process stability and reducing downtime.
