DNMG150612 T9225 Tungaloy turning insert (CVD‑coated carbide, 55°)

DNMG150612 T9225 is an ISO‑standard indexable insert designed for external and internal turning in demanding steel applications, offering a balance of toughness and wear resistance for interrupted and variable engagement conditions.

• DNMG150612 rhombic, 55° geometry
• CVD‑coated carbide grade T9225
• Robust universal grade for medium–heavy Stahl
• Double‑sided chipbreaker with cylindrical hole

Consistent performance where toughness matters

The indexable insert provides a robust solution for turning operations that encounter varying engagement and occasional interruptions. The T9225 grade is a CVD‑coated carbide composition optimised for a wide range of Stahl machining tasks, combining wear resistance with increased fracture toughness. This balance reduces the likelihood of edge chipping under unstable cut conditions and supports longer tool life in production environments. The rhombic form and 55° approach angle enable stable cutting forces and predictable toolpath behaviour, which is critical for reproducible component quality.

Mounting compatibility and secure clamping for ISO setups

Compatibility with toolholders is governed by form, relief angle, tolerance class, fastening, size and thickness; the insert’s ISO designation simplifies selection for standard holders and boring bars. The central cylindrical hole and the plate thickness of 6.35 mm permit secure clamping and consistent seating, reducing micro‑movement that can degrade surface finish. Using the appropriate holder plus matching shim or clamp set ensures optimum contact and torque distribution, which in turn supports consistent cutting performance and tool life.

Why the grade and chipbreaker matter

The double‑sided chipbreaker is engineered to control chip formation across moderate to heavy cuts, improving evacuation and reducing recut risk. For operations in Stahl, the chip control and the 1.2 mm corner radius deliver a compromise between edge strength and finishing capability: small enough for detail yet large enough to withstand shock loads. The CVD coating adds thermal and abrasive resistance, allowing stable cutting at elevated speeds compared with uncoated variants, which can translate into improved productivity when cutting parameters are optimised.

Practical application and process benefits

In production and jobbing environments, this insert supports efficient machining cycles by reducing unexpected tool change events and by offering predictable wear progression. The standard ISO format and universal grade facilitate inventory management across multiple machines and workstations. Where repeatability and throughput are priorities, the insert’s combination of geometry, coating and grade enables tighter tolerances and consistent surface quality with fewer operator interventions, contributing to overall process reliability.

FAQ

What materials is this insert suitable for?
The DNMG150612 T9225 insert is intended primarily for machining Stahl, offering a universal performance profile for medium to heavy turning tasks.

How does the T9225 grade affect cutting performance?
Tungaloy’s T9225 is a CVD‑coated carbide grade that balances wear resistance and toughness, allowing stable cutting under variable engagement and lightly interrupted cuts.

Is the insert reversible or single‑use?
The plate is double‑sided with a chipbreaker on each cutting edge; rotating the insert extends effective edge life before disposal or regrinding.

Which holder types are compatible with this ISO insert?
Compatibility is based on form, relief angle, tolerance class, fastening method, size and thickness; standard DNMG‑compatible holders and suitable clamp sets are recommended for correct seating.

What role does the 1.2 mm corner radius play?
A 1.2 mm corner radius increases edge strength and improves resistance to chipping during heavier cuts while maintaining acceptable surface finish capability.
