DNMG150408 T9225 Turning Insert — Tungaloy (CVD‑coated carbide, 55° rhombic)

A DNMG150408 T9225 indexable turning insert designed for medium to heavy steel turning, offering ISO‑compliant rhombic geometry and a robust universal grade for interrupted or variable cuts.

• CVD‑coated carbide for robust performance
• Universal T9225 grade for medium–heavy steel
• Rhombic DNMG geometry, 55° approach angle
• 0.8 mm corner radius with cylindrical hole

Durable cutting performance for mixed steel applications

The combination of CVD‑coated carbide and the T9225 grade delivers a balance of hardness and toughness suited to medium‑to‑heavy steel turning. The coating enhances wear resistance while the substrate provides the necessary toughness for mildly interrupted cuts. This results in more consistent tool life and stable cutting forces, which translates into fewer index changes and improved process reliability. The design reduces risk of edge chipping under variable engagement, supporting predictable cycle times and a steady surface finish.

Secure fit and geometry that supports productivity

Rhombic DNMG geometry with a 55° approach angle provides a versatile cutting orientation for external and internal turning. The insert’s 0° (negative) relief contributes to a stronger cutting edge and increased depth‑of‑cut capability when paired with a suitably rigid holder. Compatibility with toolholders is determined by form, clearance angle, tolerance class, attachment method, size and thickness; the ISO‑standard designation ensures straightforward selection of matched holders, shims and clamping sets. The cylindrical hole and standard thickness make mechanical seating reliable and repeatable, reducing set‑up time and improving concentricity.

Operational benefits, handling and economy

A double‑sided chipbreaker extends the usable life per insert by enabling two cutting edges per index, cutting inventory costs and downtime. The insert’s ISO standard format supports fast replacement and simple stock management across production lines. When integrated into a complete system — insert, compatible external holder or boring bar, shim/clamp set and replacement screws — handling is simplified and tool assembly becomes predictable. The net effect is improved throughput and a lower cost per component in batch and continuous manufacturing.

FAQ

Which materials is this insert best suited for?
The Tungaloy DNMG150408 T9225 insert is optimised for medium‑to‑heavy steel machining, offering robustness for slightly interrupted cuts and varying engagement conditions.

What does the 55° rhombic geometry mean for cutting?
A 55° approach provides a versatile cutting angle that balances cutting force direction and surface finish; the rhombic geometry is widely compatible with ISO holders and supports both external and internal turning.

Is the insert reversible and does it include chip control features?
Yes, the insert is double‑sided with a chipbreaker on each usable face, allowing two cutting edges per index and improved chip control during turning operations.

How is holder compatibility determined?
Compatibility depends on plate form, relief angle, tolerance class, attachment method, size and thickness; using ISO‑standard holders and the correct shim/clamp set ensures secure seating and repeatable results.

What components form a complete cutting system for this insert?
A full system typically comprises the indexable insert, a matching external holder or boring bar, a shim/clamp set and replacement screws to guarantee clamping integrity and ease of maintenance.
