DNMG150616 T9225 — DNMG indexable turning insert for medium-to-heavy steel machining by Tungaloy

DNMG150616 T9225 is an ISO-format indexable insert designed for external and internal turning, offering a balance of toughness and wear resistance for demanding steel operations.

• CVD-coated carbide T9225
• 55° rhombic geometry for versatile turning
• 1.6 mm corner radius for robust edge strength
• Double-sided chipbreaker with cylindrical hole

Reliable cutting performance for medium-to-heavy steel turning

The insert combines a CVD-coated carbide substrate with the T9225 grade to deliver consistent flank life under variable engagement conditions. The moderate toughness of the grade is engineered to absorb slight interruptions and inconsistent feeds without premature chipping, which translates into fewer unplanned insert changes and steadier cycle times. As an indexable insert, it supports cost-effective multi-edge use and reduces tool-change frequency, improving overall machining throughput.

Broad holder compatibility and straightforward machine integration

Manufactured to ISO dimensions, the rhombic format with a 55° included angle ensures compatibility with a wide range of DIN/ISO external holders and boring bars. Mounting stability is governed by form, clearance, tolerance class, fastening method, size and thickness; the cylindrical hole and standard thickness facilitate secure clamping and simple indexing. This predictability in fixture choice reduces setup time and supports repeatable part quality on both lathes and bar-feed systems.

Optimised grade and geometry for chip control and surface finish

The double-sided chipbreaker design helps form controllable chips across a variety of steel grades, minimising entanglement and improving evacuation in both continuous and slightly interrupted cuts. The 1.6 mm corner radius offers a compromise between edge strength and achievable surface finish, allowing moderately heavy cuts without sacrificing dimensional accuracy. The plate’s 6.35 mm thickness contributes to rigidity and vibration damping, which supports improved surface integrity and longer tool life.

Practical application notes and handling benefits

For turning operations, select a matching holder and chipbreaker variant that suits material, cut depth and machine stiffness; choosing the correct combination prolongs insert life and enhances process stability. The insert’s universal characteristics make it particularly suitable for production environments with mixed steels and variable part geometries. Careful attention to cutting data adapted to the T9225 grade will yield steady wear behaviour and predictable reconditioning intervals for production planning.

FAQ

What materials is this insert suitable for?
The DNMG150616 T9225 insert is specified for medium-to-heavy steel machining; the T9225 grade provides toughness and wear resistance suited to varying engagement conditions.

Does the insert fit standard ISO holders?
Yes, the insert follows ISO dimensions and the rhombic 55° geometry is compatible with standard external holders and boring bars designed for DNMG-format plates.

How does the chipbreaker influence performance?
The double-sided chipbreaker promotes consistent chip formation and evacuation, reducing the risk of chip build-up and supporting stable surface finish during turning operations.

What are the advantages of the 1.6 mm corner radius?
A 1.6 mm corner radius increases edge strength for heavier cuts while still allowing good surface quality, making it a practical choice for mixed production runs.

Is the insert reversible and indexable?
The plate is double-sided and indexable, enabling multiple cutting edges per insert which improves cost efficiency and reduces downtime for edge changes.
