DNMG 150408 T5125 Wendeplatten - Tungaloy

The combination of a CVD-coated carbide T5125 grade, ISO DNMG150408 geometry and a 0° clearance delivers reliable performance for external and internal turning, especially in interrupted cuts on cast iron; order the DNMG150408 T5125 Tungaloy insert directly via Metav Werkzeuge or ask our consultants if needed.

DNMG150408 T5125 turning insert — Tungaloy (CVD-coated carbide, 0° clearance)

The DNMG150408 T5125 Tungaloy insert is an ISO-standard, rhombic, double-sided indexable insert designed for turning applications, optimised for cast iron and interrupted cutting conditions.

• ISO DNMG150408 geometry, rhombic insert
• CVD-coated carbide, grade T5125
• 0° clearance angle, 0.8 mm corner radius
• Double-sided with cylindrical hole for secure clamping

Increased machining reliability through a tough CVD-coated grade

The CVD-coated carbide of the T5125 grade provides a tougher cutting edge that copes better with interrupted cuts and less stable setups. This material combination improves edge stability and reduces the risk of chipping when machining cast iron or similar materials, which in turn supports longer tool life and fewer part reworks. The cartridge-style wear behaviour typical of CVD coatings also makes performance more predictable, allowing planners to estimate tool-change intervals more reliably and optimise production flow.

Consistent clamping and repeatability for accurate turning

A secure clamping system is essential for repeatable results; the double-sided design with a cylindrical hole gives stable locating and fast indexability while maintaining the correct seat geometry. The ISO-standard form means compatibility with a wide range of external holders and boring bars, where fit depends on form, clearance, tolerance class, fixation method, size and thickness. The 0° clearance and 0.8 mm corner radius contribute to controlled chip formation and a consistent machined profile, reducing setup iteration and improving first-pass quality.

Application fit and economical advantages in series production

The rhombic indexable insert with a 4.76 mm thickness and 15 mm inscribed circle is suitable for both external and internal turning when paired with an appropriate holder and chipbreaker. Choosing the double-sided chipbreaker and the T5125 grade matches the insert to workpiece stability and the required surface finish, yielding lower cost per edge through multiple reuses and reduced downtime. Where interrupted cuts or unstable clamping are expected, this combination often leads to fewer rejects and a shorter payback period on tooling investment.

FAQ

Which materials is this insert best suited for?
The DNMG150408 T5125 insert from Tungaloy is optimised for cast iron applications and performs particularly well in interrupted cuts or less stable machining conditions, thanks to the tougher T5125 grade.

What does the T5125 designation indicate?
T5125 denotes a CVD-coated carbide grade engineered for toughness and reliable edge stability; in practice, the T5125 grade balances wear resistance with chipping resistance when machining cast iron.

How does the insert secure to the holder?
The insert features a cylindrical hole and an ISO-compliant seat that enable secure clamping and straightforward indexing when mounted in compatible external holders or boring bars.

What influence does the 0.8 mm corner radius have?
The 0.8 mm corner radius provides a compromise between edge strength and surface finish, offering increased robustness compared with very small radii while still delivering a controlled surface profile on turned parts.

Is the insert reversible and economical for batch work?
Yes; the double-sided design allows multiple indexings before disposal, which extends usable life per insert and reduces tooling cost per component in serial production.
