Take advantage of the CVD-coated T515 grade and ISO-standard geometry to improve throughput when turning cast iron; the rhombic DNMA110404 form with a 0.4 mm nose radius delivers consistent surface quality and stable chip formation, while compatibility with ISO holders reduces setup time — order directly via Metav Werkzeuge or ask our consultants for application support.

DNMA110404 T515 indexable turning insert, ISO grade for cast iron — Tungaloy

A DNMA110404 T515 indexable turning insert designed for economical and productive machining of cast iron in ISO-standard turning systems.

• DNMA110404 insert, rhombic 55° geometry
• CVD-coated carbide grade T515 for cast iron
• 0.4 mm nose radius for precise finishing
• Standard ISO indexable insert, 4.76 mm thick

Reliable productivity for cast-iron turning

The DNMA110404 insert is manufactured in the T515 grade with a CVD-coated surface that enhances tool life during continuous and interrupted cuts in cast iron. The coating promotes stable chip formation and wear resistance, so cycle times remain predictable and tool changes are less frequent. By selecting a grade optimised for cast iron, process efficiency is improved: the cutting edge sustains higher cutting speeds while maintaining surface integrity, leading to lower unit costs per component and reduced machine downtime.

Precision geometry for consistent surface finish

A rhombic plate form with a 55° lead angle and 0.4 mm nose radius provides a balance between strength and finish capability. The small radius helps achieve fine surface quality on profiles and external features, while the 55° geometry supports versatile tool paths for both external and internal turning. The insert features a cylindrical hole for secure clamping and a plate thickness of 4.76 mm, which together ensure stable seating in ISO-compatible holders and repeatable cutting positions. These geometric choices translate into fewer scrap parts and more consistent batch results.

System compatibility and practical application guidance

This insert is part of an ISO-standard turning insert system and is intended for use with a matching external holder or boring bar, plus the appropriate shim/clamp set and replacement screws. Compatibility depends on form, relief angle, tolerance class, fastening method, size and thickness; therefore the insert is suited to a wide range of ISO holders when these parameters match. For best performance, pair the plate with a holder that provides sufficient rigidity and choose a chipbreaker or an alternative grade according to the specific stability and cutting-speed requirements of the job. Proper selection reduces vibration, improves tool life and delivers reproducible component geometries.

FAQ

Is this insert suitable for machining cast iron?
The DNMA110404 T515 insert is specified for economical machining of cast iron; the T515 grade and CVD coating are optimised for stable chip formation and durability in that material.

What does the DNMA110404 designation indicate?
The designation DNMA110404 refers to the insert geometry and dimensions (rhombic shape, size 11, thickness 4.76 mm, nose radius 0.4 mm) used in ISO-standard turning systems.

Can the insert be used in internal and external turning?
Yes, the insert is designed for both external and internal turning when paired with a suitable ISO holder or boring bar and the correct clamping components.

Does this insert include a chipbreaker?
This variant is supplied without an integrated chipbreaker; chip control should be managed by selecting an appropriate grade, cutting parameters or a different insert variant as required.

How is compatibility with a holder determined?
Compatibility depends on insert form, relief angle, tolerance class, fastening method, size and thickness; ensure the holder matches these parameters for secure seating and repeatable cutting.
