DNMA150408 T5125 indexable insert for turning — Tungaloy

A DNMA150408 T5125 indexable insert engineered for external and internal turning, optimised for interrupted cuts and less stable machining conditions.

• CVD-coated carbide grade T5125
• Rhombic shape, 15 mm size
• 0.8 mm corner radius
• Cylindrical hole with screw fixation

Consistent performance in interrupted cuts

The CVD-coated T5125 grade provides a tougher, more fracture-resistant surface that is particularly valuable when machining cast iron under interrupted cutting conditions. By choosing a grade designed for less stable setups, the insert reduces the risk of edge chipping and unplanned downtime. The result is improved process stability and a predictable tool life that supports efficient shop-floor scheduling. Technical customers will appreciate that the coating and substrate combination is selected to balance wear resistance with impact tolerance.

ISO compatibility and secure clamping reduce setup time

Manufactured to ISO dimensions, the insert is compatible where form, free angle, tolerance class, attachment method, size and thickness match the holder. The rhombic geometry with a 55° approach angle offers versatility for both facing and light profiling, while the cylindrical hole enables secure fixation with standard clamping systems. Clear adherence to ISO standards simplifies holder selection and reduces trial-and-error during tool changes, so machine setups are faster and repeatable.

Carbide substrate and geometry for dependable edge life

The substrate is a solid carbide body combined with a CVD coating, giving a balance of toughness and wear resistance. The 0.8 mm radius supports a robust cutting edge that helps absorb shocks typical of interrupted passes, while a plate thickness of 4.76 mm contributes to mechanical strength. With this geometry, the insert maintains cutting-edge integrity under variable conditions, translating into fewer indexings per component and lower tooling consumption over time.

Practical system advice to enhance productivity

For a full tooling system, pair the insert with a matched external holder or a suitable boring bar, plus an underlay/shim set and the correct clamping screws. Since the insert has no dedicated chipbreaker in its standard form, selecting a holder and process parameters that control chip evacuation is important when machining convoluted flanks or deep grooves. Typical applications include external and internal turning where interrupted cuts or limited rigidity are anticipated. The product supports a pragmatic approach to process planning: choose holder rigidity and cutting data to match the insert’s toughness and geometry for the best economy.

FAQ

What materials is this insert best suited for? This DNMA150408 T5125 indexable insert is optimised for cast iron and similar materials where interrupted cuts or limited setup rigidity occur; the T5125 grade emphasises toughness.

Can the insert be used for internal boring as well as external turning? Yes, the rhombic geometry and ISO dimensions of the DNMA150408 T5125 insert make it suitable for both external and internal turning when paired with the correct boring bar or holder.

How does the 0.8 mm corner radius affect the machining result? A 0.8 mm radius provides a strong cutting edge that reduces chipping risk in interrupted cuts and yields a balanced surface finish suitable for many turning operations.

Which holders are compatible with this ISO insert? Compatibility depends on holder form, relief angle, tolerance class, attachment method, size and thickness; use an ISO-compliant holder matching the DNMA150408 dimensions for secure clamping.

Is a chipbreaker included with this insert? The standard version is supplied without a dedicated chipbreaker; chip control should be managed via holder choice and cutting parameters for optimal evacuation.
