DNMG 150408 T9225 – Turning insert for medium-to-heavy steel machining (Tungaloy)

The DNMG150408 T9225 insert is a CVD-coated, carbide indexable insert designed for robust external and internal turning applications.

ISO DNMG rhombic format for wide compatibility
CVD-coated T9225 grade for robust steel turning
Double-sided chipbreaker for reliable chip control
0° clearance angle with cylindrical hole mounting

Consistent performance under variable cutting conditions

The combination of a CVD-coated surface and the T9225 carbide composition delivers a balanced hardness-to-toughness ratio suited to varied engagement conditions. This makes the insert particularly effective where interrupted cuts or fluctuating feed demands occur. The coating reduces flank wear and improves tool life, while the substrate retains impact resistance; together these factors promote predictable process stability and fewer unscheduled tool changes.

Fast, repeatable clamping and minimal setup time

The ISO rhombic geometry and standardised attachment features ensure that the insert seats reliably in compatible holders. The presence of a cylindrical hole and the specified thickness (4.76 mm) facilitate repeatable mounting and safe torque transmission with standard clamping kits. Reduced setup time and straightforward replacement lead to increased machine uptime and quicker return to production after tool changes.

Improved chip control and surface integrity

A double-sided chipbreaker integrated into the insert geometry supports consistent chip formation across a range of cutting parameters. This improves evacuation in both external and internal turning and reduces the risk of re-cutting chips. The rhombic shape, combined with a 0° clearance angle, provides an advantageous edge strength that helps achieve reliable dimensional accuracy and surface finish on medium-to-heavy steel components.

Clear selection criteria for reliable outcomes

For external or internal turning, select the chipbreaker and grade to match material, cut depth and machine rigidity; the DNMG150408 insert is aimed at medium-to-heavy steel machining where robustness and repeatable performance are priorities. Choose a matching ISO-compliant holder that accounts for form, tolerance class, size and thickness to ensure optimal compatibility and safe operation. For uncertain applications, technical specification checks are recommended before final selection.

FAQ

What materials is this insert suitable for?
The DNMG150408 T9225 insert is formulated for medium-to-heavy steel machining; the T9225 grade offers toughness for interrupted cuts and variable engagement.

How does the T9225 grade affect tool life?
The CVD-coated T9225 grade combines wear resistance with toughness, which extends effective tool life under common turning loads while maintaining stable chip formation.

Is the insert reversible or single-use per edge?
The rhombic DNMG format is double-sided with a double-sided chipbreaker, allowing use of multiple cutting edges to maximise productivity.

What holder characteristics are required for compatibility?
Compatibility depends on the insert form, clearance angle (0°), tolerance class, fastening method, size and thickness; a matching ISO DNMG holder or appropriate boring bar is required.

Can this insert be used for finishing and roughing?
Yes, with appropriate selection of chipbreaker and cutting parameters the insert supports both finishing and heavier roughing operations in steel.
