DNMG 150408 T9235 Wendeplatten - Tungaloy

The CVD-coated carbide T9235 combined with the rhombic DNMG geometry and 55° cutting angle delivers robust performance for turning operations in Stahl, especially under interrupted or unstable cutting conditions; order the DNMG150408 insert directly via Metav Werkzeuge or contact our consultants for holder compatibility.

DNMG 150408 T9235 Tungaloy insert — Turning, CVD-coated carbide, 55° rhombic

The DNMG150408 T9235 Tungaloy insert is an ISO-standard, rhombic indexable insert designed for external and internal turning, optimised for machining Stahl where interrupted cuts or reduced cutting speeds demand a tough grade and reliable chip control.

• CVD-coated carbide grade T9235
• Rhombic DNMG geometry, 55° cutting angle
• 0° clearance angle for stable turning
• Double-sided, cylindrical hole; 4.76 mm thickness

Delivering reliable results in demanding turning operations

The combination of a CVD-coated surface and a carbide substrate in grade T9235 is engineered for toughness rather than maximum speed, which makes the insert particularly suitable for interrupted cuts and unstable set-ups. The chemical vapour deposition layer increases wear resistance while preserving edge strength; this reduces the frequency of edge failure in mixed or challenging material batches. For operations where feed fluctuation or sporadic chip engagement occurs, the indexable insert provides a predictable service life, lowering the need for unscheduled tool changes and supporting more consistent production throughput.

Geometry and chip control that improve surface quality

The rhombic DNMG form with a 55° cutting angle and a 0.8 mm corner radius balances strength and finish. A larger corner radius increases edge robustness, helping to resist chipping during interrupted cuts, while the 55° relief promotes accessibility on external and internal profiles. The double-sided chipbreaker design with a cylindrical hole supports repeatable chip formation and straightforward indexing; by maintaining consistent chip separation and evacuation, vibration is reduced and surface quality is improved in many turning scenarios.

Economy through durability and predictable performance

Selecting a grade that prioritises toughness, such as T9235, leads to fewer insert replacements in the long run when machining Stahl under lower cutting speeds or unstable conditions. The CVD-coated carbide provides a balanced wear resistance that is cost-effective in applications where coatings designed for maximum speed would otherwise fail prematurely. Reduced downtime for tool changes and fewer rejects contribute to a more economical process without sacrificing the ability to handle occasional interruptions in the cut.

Compatibility and practical workshop guidance

Compatibility with toolholders is determined by insert form, clearance angle, tolerance class, fixation method, size and thickness. The DNMG designation and the ISO code 150408 indicate a 15 mm inscribed circle and a plate thickness of 4.76 mm, with a 0° clearance specification that must match the chosen holder geometry. Typical tool assembly comprises the insert, a matching external holder or boring bar, a support shim or clamping kit and the appropriate clamping screws. When replacing inserts, ensure that the holder accepts a rhombic DNMG plate with a cylindrical hole and that the tolerance class aligns with the intended cutting parameters for stable clamping and accurate seating.

FAQ

Is the DNMG150408 T9235 insert suitable for interrupted cuts?
The DNMG150408 T9235 Tungaloy insert is designed with a tough T9235 grade and CVD coating, making it well suited to interrupted cuts and unstable engagement conditions when machining Stahl.

Which materials are recommended for this insert?
This insert is optimised for machining Stahl; the CVD-coated carbide T9235 provides toughness and wear resistance for such applications rather than maximum-speed finishing on non-ferrous materials.

Can the insert be indexed to use both sides?
Yes, the DNMG150408 is double-sided; each indexing operation provides a fresh cutting edge, and the cylindrical hole assists secure and repeatable clamping (SKU: 6786015-Tungaloy).

What dimensions should be checked before fitting the insert?
Check the key dimensions: 15 mm inscribed circle, 4.76 mm plate thickness, 0.8 mm corner radius and the 55° geometry to ensure the chosen holder and shim match the DNMG150408 specification.

How should the chipbreaker and holder be selected?
Select a chipbreaker that fits the machining stability and feed range; the DNMG150408 with its double-sided chipbreaker is versatile, but holder compatibility depends on matching form, clearance angle, tolerance and fixation for reliable clamping.
