DNMG150412 T5125 — Indexable turning insert for turning applications by Tungaloy

A DNMG150412 T5125 indexable turning insert developed for external and internal turning, especially suited to cast iron in interrupted cuts or less stable setups.

• CVD-coated carbide grade T5125
• Rhombic DNMG 15 geometry with 55° included angle
• Double-sided chipbreaker for flexible machining
• Cylindrical centre hole for secure clamping

Reliable cutting performance for cast iron and mixed conditions

The combination of a CVD-coated carbide substrate and the T5125 grade delivers a tougher cutting edge designed for interrupted cuts and unstable set-ups commonly encountered when turning cast iron. The coating provides abrasion resistance while the substrate maintains edge strength, resulting in consistent tool life and reduced risk of premature edge chipping. This balance of hardness and toughness supports productive machining cycles and helps to safeguard surface finish when conditions vary.

Secure fit and proven ISO compatibility for straightforward integration

Engineered to ISO geometry standards, the insert features a rhombic DNMG 150412 form with a cylindrical centre hole and a plate thickness of 4.76 mm, ensuring compatibility with standard holders when the form, relief angle, tolerance class, fastening method, size and thickness are matched. The 0° clearance angle and 1.2 mm nose radius are specified to aid in repeatable seat location and predictable cutting behaviour. Clear, standardised dimensions simplify tool selection and reduce the need for trial-and-error during setup.

Practical chip control and handling benefits that aid productivity

The double-sided chipbreaker offers two usable cutting edges per side, extending effective productivity before indexation is required. The insert’s geometry and chipbreaker design improve chip formation and evacuation in common turning operations, which can reduce cycle interruptions and improve machine uptime. Supplied in the ISO turning insert system, the component integrates into a set-up comprising a matching external holder or boring bar, a shim/clamping set and replacement screws, allowing for efficient maintenance and quick reassembly on the shopfloor.

FAQ

Is this insert suitable for interrupted cuts in cast iron?
Yes. The DNMG150412 T5125 insert is specifically graded (T5125) and CVD-coated for tougher performance in cast iron, particularly under interrupted cutting conditions.

How many usable cutting edges are available before indexing?
The insert features a double-sided chipbreaker, providing multiple usable edges; the exact count depends on the mounted orientation and chosen side during indexing.

Which holders are compatible with this geometry?
Compatibility depends on holder form, relief angle, tolerance class, fastening and size; the ISO DNMG 150412 geometry matches standard DNMG external holders and suitable boring bars.

What are the key dimensions to check when selecting a seat and clamp?
Check the insert size (15 mm), plate thickness (4.76 mm), corner radius (1.2 mm) and the presence of a cylindrical centre hole for secure clamping when selecting the seat and clamp.

Can the insert be used for finishing operations on cast iron?
The T5125 grade and chipbreaker optimise performance for robust cutting; for fine finishing requirements, consider the required surface finish and cutting parameters, as the insert is primarily designed for reliable cutting under variable conditions.
