DNMG150608 T5125 turning insert for turning by Tungaloy

The DNMG150608 T5125 is an ISO-standard rhombic turning insert designed for external and internal turning of cast iron, offering robust edge strength for interrupted cuts.

• CVD-coated carbide for higher toughness
• Optimised for cast iron and interrupted cuts
• Rhombic 15 mm form with 6.35 mm thickness
• Cylindrical hole and double-sided chipbreaker

Reliable cutting performance with a tougher grade

The T5125 grade is a CVD-coated carbide formulation developed for increased toughness in demanding cast-iron applications. Thanks to its balanced substrate and coating combination, the grade reduces edge chipping during interrupted machining and when working with less rigid set-ups. This results in more consistent tool life, fewer unplanned indexings and improved process stability, which together support higher productivity on parts that require frequent engagement and disengagement of the cutting edge.

Clear geometry and ISO compatibility to simplify tooling choices

The insert follows ISO dimensions and the rhombic form provides a versatile 55° cutting angle suitable for diverse turning tasks. With a nominal size of 15 mm and a plate thickness of 6.35 mm, the geometry ensures mechanical stability in typical external and internal turning operations. The insert features a 0.8 mm corner radius that balances edge strength and surface finish. Compatibility with a holder depends on form, clearance angle, tolerance class, fastening method, size and thickness — matching these parameters enables reliable clamping and repeatable results.

Integration into a complete turning system

This ISO insert is designed to work as part of a system comprising a suitable external holder or boring bar, a shim/clamp set and replacement screws. The insert’s cylindrical hole and double-sided chipbreaker support straightforward mounting and economical use of both cutting edges. Selecting the correct chipbreaker and the T5125 grade according to workpiece material and stability will optimise chip control and surface integrity, reducing secondary operations and increasing throughput on cast-iron components.

Better throughput and predictable results in daily machining

Using a purpose-engineered grade and standardised geometry enables predictable tool change intervals and stable chip formation. The combination of CVD-coated carbide toughness and an ISO-compliant insert form helps to avoid sudden edge failure and supports consistent surface quality. For operations where reliability and repeatability matter, this approach lowers scrap rates and contributes to efficient, cost-effective production over longer runs.
