• CVD-coated carbide, grade T5125
• Rhombic form with 55° included angle
• 0.4 mm corner radius for stable cuts

Reliable edge performance for interrupted turning

The combination of a CVD-coated carbide substrate and the specifically developed T5125 grade provides a tougher coating concept that favours resilience under varying cutting forces. As a result, the insert maintains a consistent cutting edge where interruptions and unstable setups occur, reducing the risk of premature chipping. This design choice prioritises process security and longer tool life, which translates directly into fewer index changes and improved productivity on batch or mixed-series turning operations.

Clear compatibility requirements and mounting guidance

Compatibility with a toolholder depends on geometric match: the insert form, 55° included angle, relief geometry, tolerance class, fastening method, size and thickness must correspond. The inserted part features a cylindrical hole to assist accurate seating and clamping. When selecting a holder or boring bar, ensure that seat profiles and clamping screws match the ISO seat and tolerance ranges; correct clamping prevents micro-movement that would otherwise shorten edge life and impair repeatability in serial production.

Material and coating explained for practical decisions

The insert’s carbide body with a CVD-coated top layer is optimised for machining cast iron, where consistent chip breakage and wear resistance are critical. The T5125 grade is a tougher variant intended to absorb impact loads typical of interrupted cuts and less rigid setups. Note that this particular insert is supplied without a chipbreaker, so cutting parameters should be set with chip evacuation in mind; selecting a compatible holder or external chip control measures will support safe and efficient operation.

Handling, recommended parameters and benefits at a glance

With a 0.4 mm corner radius and 4.76 mm thickness, the insert offers a balance between edge strength and achievable surface finish. The rhombic geometry suits both external and internal turning where a 55° approach is advantageous for profile work. For best results in roughing interrupted sections of cast iron, favour moderate feeds and stable cutting depths; this preserves the edge and leverages the insert’s toughness. Proper selection of clamping torque and verification of seat contact will sustain reliable repeatability.

FAQ

What materials is this insert best suited for?
The DNMA150404 T5125 indexable insert is primarily intended for machining cast iron; the T5125 grade provides toughness suited to interrupted cuts and less rigid set-ups.

Is the geometry compatible with ISO holders?
Yes. The insert follows ISO turning insert conventions, and compatibility depends on matching form, relief angle, tolerance, fastening, size and thickness to the chosen holder.

What does the T5125 designation indicate?
T5125 denotes a CVD-coated carbide grade engineered for tougher applications, delivering improved impact resistance and stable wear behaviour in cast iron turning.

Are chipbreakers included with this insert?
This variant is supplied without a chipbreaker, so chip control must be achieved via holder selection, cutting parameters or external measures when required.
