DNMG150408 T505 – Indexable turning insert for turning applications by Tungaloy

A DNMG150408 T505 indexable turning insert designed for economical and productive machining of cast iron components.

• DNMG150408 ISO rhombic insert, 55° cutting angle
• CVD-coated carbide T505 for cast iron machining
• Double-sided chipbreaker, economical indexing
• Cylindrical hole for secure clamp mounting

Productive cast-iron turning with a grade built for economy

The CVD-coated carbide grade T505 is engineered for the efficient machining of cast iron, combining wear resistance with consistent cutting performance. As an indexable turning insert, it provides multiple usable edges so tool changeover is fast and waste is reduced; this supports continuous production runs and lowers per-part machining costs. The substrate and coating pairing ensures stable chip formation under typical interrupted and continuous turning conditions, translating directly into more predictable tool life and fewer unplanned stoppages.

Compatibility and secure mounting for reliable process set-up

Compatibility depends on form, relief angle, tolerance class, fixation and size; the rhombic ISO DNMG150408 shape with a cylindrical hole fits common DIN-compatible holders when matched to the correct tolerance and clamping system. The insert’s 0° relief angle and 55° lead angle help define cutting geometry for finishing and medium-depth roughing tasks. A 0.8 mm corner radius balances edge strength and surface finish, making the insert suitable for both general turning and operations where a controlled corner is required.

Process benefits: chip control, indexing and handling

The double-sided chipbreaker is designed to promote predictable chip breaking on grey and nodular cast irons, improving machine cleanliness and operator safety. Being double-sided affords two usable cutting edges per orientation, which enhances economy by extending productive life before indexing or replacement. The secure clamping enabled by the cylindrical hole and standard screw fixation reduces the risk of insert movement under load, thereby maintaining dimensional accuracy and repeatability of machined parts.

Choosing the right application and getting the most from the insert

Select the appropriate chipbreaker and grade relative to workpiece stability, cutting speed and interruption severity; the T505 composition is particularly suited to cast-iron applications but requires correct holder geometry to deliver the promised results. For mixed production where different materials are encountered, verify compatibility with the chosen holder and consider reserve stocks of inserts to avoid production delays. Clear documentation of holder type, clamp style and tolerance class will speed up correct selection and reduce the risk of mismatch.

FAQ

What materials is this insert intended for?
The Tungaloy DNMG150408 T505 insert is specified for economical machining of cast iron; the T505 grade with CVD coating is optimised for chip formation and tool life on such materials.

How is the insert secured in the holder?
The insert features a cylindrical hole and is clamped using standard screws; when paired with the correct DIN-compatible holder and clamping kit the DNMG150408 ensures secure positioning and repeatable accuracy.

How many usable edges are available per insert?
This rhombic, double-sided insert provides multiple usable cutting edges; the double-sided chipbreaker allows rotation to fresh edges, extending productive life before replacement.

Which cutting geometry considerations are important for the DNMG150408?
Key geometry data are the 55° cutting angle and 0° relief angle combined with a 0.8 mm corner radius; these parameters influence cutting forces, surface finish and edge strength during turning operations.

Is the DNMG150408 T505 suitable for interrupted cuts?
Yes, the T505 composition and chipbreaker design are selected to cope with interrupted and continuous cuts typical in cast-iron turning, though holder rigidity and cutting parameters must be adapted to the specific operation.
