DNMA150404 T5115 indexable insert for turning by Tungaloy — rhombic 55°

DNMA150404 T5115 is an ISO‑compliant indexable turning insert designed for versatile external and internal turning, with a rhombic geometry suited to stable setups and a broad range of cast‑iron applications

• CVD-coated carbide grade T5115
• Rhombic form with 55° included angle
• 0° relief, 0.4 mm nose radius
• With cylindrical hole for screw clamping

Consistent wear behaviour and edge stability for cast iron

The CVD-coated carbide composition of the grade T5115 delivers an optimised balance between wear resistance and edge strength for cast‑iron machining. The coating reduces flank wear and thermal degradation during extended cuts, which results in fewer index changes and more predictable tool life. In practice, this means steadier cycle times and reduced downtime in series turning operations when the cutting parameters are set for the workpiece and machine stability.

Geometry and clamping that support repeatable quality

The rhombic insert geometry with a 55° included angle combined with a 0° relief and 4.76 mm thickness provides a robust cutting edge and straightforward clamping. The 0.4 mm nose radius helps produce a controlled surface finish while preserving edge integrity under variable cutting depths. The insert includes a cylindrical hole for positive screw clamping; when used with a correctly specified ISO holder, the system delivers repeatable seating and concentricity for predictable results.

Versatility in turning operations and clear application scope

Designed primarily for turning, the insert is supplied without a chipbreaker, making it suitable for operators who select chip control via seat geometry, cutting data or dedicated holder features. The universal character of the grade makes it appropriate for external and internal turning of cast iron where a balance of productivity and edge life is required. Stable fixturing and appropriate coolant or cutting conditions are recommended to exploit the full potential of the grade.

System approach for reliable implementation on the machine

Being part of an ISO-compliant range, the insert is intended to work as a system: an ISO indexable insert, a matching external holder or boring bar, backing/clamping set and replacement screws. Compatibility is determined by form, relief angle, tolerance class, fastening, size and thickness, so selecting a holder that matches the ISO DNMA150404 dimensions ensures secure assembly and consistent cutting geometry on every index change.

FAQ

What materials is this insert intended for?
The DNMA150404 T5115 insert from Tungaloy is a universal grade primarily intended for machining cast iron, offering a balanced combination of wear resistance and edge stability.

How is the insert clamped in the toolholder?
Clamping is via a screw through the cylindrical hole; the DNMA150404 indexable insert seats against the holder using the specified form, tolerance and thickness for secure fixation.

Is there a chipbreaker on this insert?
No, this variant is supplied without a chipbreaker, so chip control must be achieved through holder choice, cutting parameters or external chip‑control measures when using the T5115 grade.

Which dimensions are critical when selecting a matching holder?
Select a holder matching the ISO‑designation DNMA150404 in terms of form, relief angle (0°), thickness (4.76 mm) and inscribed circle (15 mm) to ensure correct seating and repeatable geometry.

Can this insert be used for internal turning?
Yes, the geometry and grade permit both external and internal turning; ensure the chosen boring bar or internal holder provides sufficient rigidity for the intended cutting parameters.
