DNMG150408 T5125 turning insert — CVD-coated carbide, 0.8 mm radius, for turning · Tungaloy

The DNMG150408 T5125 is an ISO-standard turning insert designed for external and internal turning, optimised for cast iron machining and interrupted cuts, with a rhombic form and a cylindrical hole for secure mounting.

• CVD-coated carbide grade T5125
• Optimised for cast iron machining
• Double-sided chipbreaker for stability
• Rhombic ISO insert 15 mm, 0.8 mm radius

Consistent performance under interrupted cuts and unstable setups

The CVD-coated carbide grade T5125 is formulated as a tougher CVD-coated carbide to resist chipping during intermittent engagement and less rigid setups. That makes it well suited to applications with workpiece irregularities or interrupted cuts in cast iron. The result is longer tool life and fewer unplanned indexings, which supports continuous machining and reduces downtime.

Stable cutting geometry for surface quality and repeatability

A double-sided chipbreaker combined with a 0.8 mm corner radius and rhombic shape provides a predictable chip flow and reduced vibration when turning. The 4.76 mm thickness and 0° rake angle contribute to a rigid cutting edge that produces a consistent surface finish and dimensional repeatability across batches. For operations where stability and finish matter, this geometry reduces the need for secondary operations.

Easy integration into ISO tooling systems and clear handling benefits

As an ISO turning insert, compatibility with holders depends on form, relief angle, tolerance class, fastening method, size and thickness; the cylindrical-hole design and standard dimensions simplify selection of matching external holders or boring bars. Typical system components include a compatible holder, a shim or clamping set, and replacement screws. This standardisation shortens setup time and helps maintain process reliability when changing inserts or retooling production.

FAQ

What materials is this insert best suited for?
The DNMG150408 T5125 insert is optimised for cast iron and performs reliably in interrupted cuts thanks to the tougher T5125 carbide grade.

Can the insert be used for external and internal turning?
Yes, the rhombic form and ISO standard make the insert suitable for both external and internal turning operations when paired with a compatible holder.

How does the chipbreaker affect machining?
The double-sided chipbreaker on this insert ensures controlled chip formation and improved stability, which helps maintain surface quality and reduce chatter.

What does the 0.8 mm radius mean for cutting results?
A 0.8 mm corner radius provides a balance between edge strength and the achievable surface finish; it is robust enough for interrupted cuts while still delivering acceptable finish in many turning tasks.
