Take advantage of the combination of CVD-coated carbide toughness, rhombic DNMG geometry and a 1.2 mm corner radius for stable, cost-effective medium-to-heavy steel turning; consult Metav Werkzeuge for compatibility with existing holders or order directly via Metav Werkzeuge if stock is required.

DNMG150412 T9225 — Indexable turning insert, rhombic 55° (Tungaloy)

A DNMG150412 T9225 indexable insert engineered for ISO-compliant external and internal turning in medium-to-heavy steel applications.

• CVD-coated carbide grade T9225
• Robust universal grade for steel machining
• Rhombic DNMG geometry, 55° lead angle
• Double-sided insert with cylindrical hole

High-performance cutting for reliable production

The DNMG150412 T9225 insert combines a CVD-coated carbide substrate with a robust universal grade that is optimised for medium-to-heavy steel turning where variable engagement conditions demand extra toughness. This construction supports stable chip formation and reduces the frequency of tool changes, leading to measurable time savings on repetitive operations. The grade’s balance of hardness and toughness helps maintain cutting edge integrity under light interruptions, making it suitable for batch and mixed-production environments where consistent results are required.

Geometry and compatibility for predictable results

The rhombic geometry with a 55° lead angle and a corner radius of 1.2 mm provides a versatile cutting profile that improves tool life and surface finish when matched to the correct holder. The insert’s 0° relief angle and 4.76 mm plate thickness contribute to rigidity; being double-sided with a cylindrical hole increases economic return per insert. Compatibility with ISO indexable holders is determined by form, relief angle, tolerance class, clamping and size, so matching the insert’s specifications to the machine holder ensures repeatable, precise engagement and reduces vibration during turning.

Practical selection and machining guidance

Select the T9225 chipbreaker and grade according to workpiece material, cutting parameters and machine stability; the double-sided design supports cost-efficiency by offering two usable edges per index. For mixed or interrupted cuts, this grade’s toughness reduces the risk of premature edge failure while still delivering effective wear resistance. When adapting cutting data, prioritise modest increases in feed over speed to preserve edge life, and confirm holder compatibility to exploit the insert’s ISO-conformity and achieve consistent surface quality.

FAQ

What materials is this insert best suited for?
The DNMG150412 T9225 insert is formulated for medium-to-heavy steel machining; the T9225 CVD-coated carbide offers toughness and wear resistance appropriate for variable engagement conditions.

How does the 55° lead angle influence cutting behaviour?
A 55° lead angle on the rhombic insert reduces radial cutting forces and improves chip flow, helping the DNMG150412 T9225 deliver better surface finish and extended edge life under many turning conditions.

Is the insert reversible and how many cutting edges are available?
This is a double-sided insert with indexing capability, so each insert provides multiple usable edges, supporting improved cost-efficiency per cutting edge for serial production.

Which holder characteristics must be checked for compatibility?
Compatibility depends on holder form, relief angle, tolerance class, clamping method, size and thickness; ensure the holder matches the DNMG150412 dimensions and the ISO interface to guarantee secure clamping and repeatable results.

What are the plate thickness and corner radius of this insert?
The insert has a plate thickness of 4.76 mm and a corner radius of 1.2 mm, values that contribute to rigidity and a balanced cutting profile for general steel turning.
