DNMG 150404 T9215 – ISO turning insert for turning by Tungaloy

A DNMG150404 T9215 indexable insert designed for medium steel external and internal turning, combining high wear resistance with fracture toughness for continuous to slightly interrupted cuts

• CVD-coated carbide T9215 for steel machining
• Rhombic 55° geometry for versatile turning
• 0.4 mm corner radius for precise profiles
• Double-sided with cylindrical hole for secure clamping

Consistent tool life through optimised coating and grade

The combination of a CVD coating with a T9215 grade carbide substrate provides a balanced mix of wear resistance and fracture toughness, which supports longer tool life in medium steel turning. For machining operations that alternate between continuous and slightly interrupted cuts, the coating reduces flank wear and the substrate maintains edge stability, resulting in fewer indexings and more productive machining cycles. This technical composition translates into measurable process reliability and lower tooling consumption over time.

Geometry and edge preparation that improve part quality

The rhombic 55° geometry and 0.4 mm corner radius enable controlled chip formation and precise profile reproduction on the workpiece. The 55° lead angle reduces cutting force peaks while preserving surface finish; the small corner radius is suited to fine turning and profile work where dimensional accuracy matters. These geometric choices reduce vibration risk and contribute to a repeatable surface quality, making the insert suitable for components with tight tolerances.

Secure clamping and compatibility with ISO holders

Featuring a cylindrical hole and double-sided design, the insert offers reliable seating and economical indexability. The ISO designation ensures compatibility with standard holders when form, clearance angle, tolerance class, screw fastening, size and thickness are matched. Use with a correctly specified external holder or boring bar ensures clamping stability, reduced run-out and uniform cutting conditions, which together minimise the likelihood of unexpected edge failure.

Practical advantages for workshop efficiency

The insert is engineered for efficient tool management: being double-sided halves part costs per usable edge, while the T9215 composition supports high productivity in batch and single-piece flows alike. Reduced flank wear and stable chip control lower rework rates and help maintain cycle time targets. For workshops aiming to balance throughput and component quality, this grade supports predictable tool-change intervals and straightforward inventory handling.

Choosing the right machining parameters and insert pairing

Selecting suitable feeds, speeds and a matching chipbreaker is key to exploiting the insert’s properties. The T9215 grade performs best in medium steels; pairing with a compatible chipbreaker and a stable toolholder yields optimised chip evacuation and surface finish. When application specifics are unclear, consult tooling data sheets or the technical team to determine cutting parameters that match material, operation type and machine capability.

FAQ

Which materials is this insert best suited for?
The DNMG150404 T9215 insert is optimised for medium steel machining; the CVD-coated carbide composition offers a balance of wear resistance and toughness tailored to such materials.

Can the insert handle interrupted cuts?
Yes, the T9215 grade combines fracture resistance with wear performance, making the insert suitable for continuous to slightly interrupted cutting conditions.

How does the rhombic geometry affect cutting?
The 55° rhombic geometry reduces cutting forces and improves access to external and internal contours, supporting stable cutting and consistent surface finish when used with the correct holder.

Is the DNMG150404 compatible with standard ISO holders?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; when matched, the insert seats securely in standard ISO external or boring holders.

What are the inventory and clamping advantages of this design?
Being double-sided with a cylindrical hole, the insert provides economical indexing and secure clamping, reducing per-edge cost and supporting reliable seat engagement in the toolholder.
