DNMG150404 T5125 — Turning indexable insert, CVD-coated carbide, 55° (Tungaloy)

The DNMG150404 T5125 is an ISO-format indexable turning insert designed for external and internal turning; its tougher CVD-coated grade is intended for cast iron and interrupted cuts.

• CVD-coated carbide grade T5125
• Rhombic insert with 55° cutting angle
• 0.4 mm corner radius for accurate contours
• Double-sided chipbreaker and cylindrical hole

Stable cutting performance for demanding turning tasks

The combination of a CVD-coated surface and a carbide substrate provides a balance between toughness and wear resistance that suits interrupted cuts and less rigid set-ups. The chosen grade, T5125, is formulated to tolerate impact during irregular engagement, which reduces unexpected tool failures and extends service intervals. In practice, this means more consistent component quality and fewer stoppages, contributing directly to process efficiency and predictable cycle times.

Secure seating and broad holder compatibility for reliable set-up

Compatibility with the toolholder is determined by form, clearance angle, tolerance class, fixation, size and thickness; the rhombic geometry and 55° lead angle ensure a stable contact point in both external and internal turning applications. The insert is furnished with a cylindrical hole, allowing positive clamping and simple locating in standard ISO external holders or boring bars. Clear specification of dimensions and tolerances simplifies holder selection and reduces set-up time, supporting repeatable production runs.

Practical chip control and finishing for improved surface quality

A double-sided chipbreaker paired with a 0.4 mm radius produces controllable chip formation and a consistent cutting edge for fine contours and finishing passes. The double-sided design effectively offers two usable edges per index, optimising tool use and lowering tooling cost per component. Where high surface quality and dimensional stability are required, selecting the appropriate chipbreaker and the T5125 grade helps to maintain edge integrity and minimise built-up edge during intermittent cutting.

Choose the Tungaloy DNMG150404 T5125 insert for applications that demand impact resistance and consistent chip control; contact Metav Werkzeuge for specification matching and procurement assistance.

FAQ

What materials is this insert best suited for?
The DNMG150404 T5125 insert is optimised for cast iron applications and performs well in interrupted cuts or less stable machining conditions due to its tougher T5125 CVD-coated carbide grade.

Which toolholders are compatible with this insert?
Compatibility is governed by form, clearance angle, tolerance class, fixation, size and thickness; the rhombic shape and cylindrical hole of the DNMG150404 permit use in standard ISO external holders and boring bars designed for 55° inserts.

Is the insert indexable and how many cutting edges are usable?
Yes — the insert is double-sided with a double-sided chipbreaker, offering two usable cutting edges per index, which enhances economy and reduces changeover frequency.

How does the 0.4 mm corner radius affect finish and strength?
A 0.4 mm radius provides a compromise between a fine contour for finishing and sufficient edge strength for interrupted or less stable turning operations, improving surface quality while maintaining reliable edge life.
