DNMG 150412 T505 turning indexable insert by Tungaloy

The DNMG150412 T505 Tungaloy insert is an ISO‑standard, rhombic indexable insert developed for economical and stable turning of cast iron, offering reliable chip control and consistent tool life in production environments.

• CVD-coated T505 grade for economical machining
• Suited for cast iron turning operations
• Rhombic DNMG geometry, 55° cutting angle
• Double-sided chipbreaker, 1.2 mm corner radius

Consistent machining performance for cast iron turning

The combination of a CVD-coated surface and a wear‑resistant carbide substrate in the T505 grade delivers measurable endurance when machining cast iron, reducing insert changes and downtime. The rhombic geometry with a 55° included angle provides a stable cutting edge that resists vibration in less rigid set‑ups, while the double‑sided chipbreaker improves chip form and evacuation. This results in steadier surface finish and extended tool life, which supports predictable cycle times and reduced process variability.

Secure seating and compatibility ensure reliable production cycles

The ISO‑format design of the insert ensures compatibility with standard DNMG holders when matched by form, tolerance class, fastening method, size and thickness. The cylindrical hole and nominal thickness of 4.76 mm allow secure clamping and accurate repeatability across index changes, supporting uninterrupted production. Clear specification and standardisation simplify tooling logistics: replacement inserts maintain the same datum points, which reduces set‑up time and preserves machining parameters from one index to the next.

Productivity gains through optimised chip control and geometry

With a 1.2 mm corner radius and a tailored chipbreaker geometry, this insert is tuned for interrupted and continuous cuts commonly encountered in turning cast iron components. The chip former minimises re‑cutting and helps to prevent chip entanglement on long parts, enhancing operator safety and machine uptime. When paired with appropriate cutting parameters, the insert’s T505 formulation delivers a favourable cost‑per‑component ratio by balancing wear resistance with economical edge life.

Practical guidance for integration into the shop floor

Select a matching DNMG‑type external holder with suitable rigidity and clamping torque to exploit the insert’s strengths. For roughing passes where higher material removal is required, opt for slightly reduced cutting speeds and increased feed to maintain chip control; for finishing, the combination of CVD coating and rhombic geometry supports improved surface quality. The insert’s ISO conformity simplifies matching across toolholders and makes stocking and rotation straightforward for production‑oriented workshops.

FAQ

What materials is this insert best suited to machine?
The DNMG150412 T505 insert is formulated for cast iron machining; the T505 CVD coating and carbide substrate are balanced to provide economical performance on grey and nodular cast irons.

Which holders are compatible with this insert?
Compatibility depends on holder form, tolerance class, clamping method, size and thickness; ISO‑compliant DNMG external holders designed for a 15 mm inscribed circle and 4.76 mm thickness are appropriate for the DNMG150412 T505 insert.

How does the chipbreaker design affect cutting results?
The double‑sided chipbreaker promotes controlled chip formation and evacuation, reducing re‑cutting and improving surface finish during both continuous and interrupted turning operations.

How many usable cutting edges are available per insert?
As a double‑sided DNMG insert, it provides multiple indexable edges; the exact number of edges depends on the insert geometry and indexing routine specified by the toolplan.

Is the insert suitable for interrupted cuts?
Yes — the combination of the T505 grade and the rhombic geometry gives good edge stability for interrupted turning, provided the holder and set‑up offer sufficient rigidity.
