DNMG150408 T9225 DNMG Turning Insert — Tungaloy, rhombic 55° with 0.8 mm radius

DNMG150408 T9225 is an ISO‑standard rhombic turning insert designed for external and internal turning in demanding steel applications.

• ISO‑standard rhombic 55° geometry
• CVD‑coated carbide grade T9225
• 0.8 mm corner radius for robust edge
• Double‑sided chipbreaker with cylindrical hole

Productivity gains for medium to heavy steel turning

The proven CVD‑coated carbide grade T9225 provides a balance of toughness and wear resistance, making it suitable for medium to heavy steel machining and for operations involving light interruption. The coating enhances thermal stability and reduces flank wear, which translates into longer tool life and fewer indexings. As a result, cycle times are stabilised and machine uptime improves, delivering measurable gains in process efficiency without sacrificing surface quality.

Reliable fit and dimensional clarity with ISO geometry

The rhombic 55° geometry and ISO designation ensure predictable seating in standard holders; compatibility is governed by form, clearance angle, tolerance class, attachment method, size and thickness. With a 0° clearance angle, an inscribed circle of 15 mm and a plate thickness of 4.76 mm, this insert integrates into common tooling systems when the corresponding holder and clamping set match these dimensions. Clear reference to these attributes simplifies procurement and reduces setup time on the shop floor.

Edge strength and chip control for consistent finishes

A 0.8 mm corner radius provides a robust cutting edge that withstands varying engagement conditions and intermittent cuts, while the double‑sided chipbreaker aids in forming short, controllable chips for steel. Together these features contribute to improved surface integrity and repeatable part quality. The cylindrical hole assists reliable clamping and consistent seat positioning, which supports stable cutting conditions and reduces vibration-related tool wear.

Practical selection guidance and system components

When selecting grade and chipbreaker, pair the insert with a holder suited to the intended depth of cut and rigidity of the setup. For external and internal turning operations the system typically comprises the ISO turning insert, a matching external holder or boring bar, a support shim/clamping set and replacement screws. Choose the chipbreaker and the T9225 grade when process stability and a broad material range are priorities; alternative grades or finer radii are preferable where lighter cuts or finer surface finish are required.

FAQ

Is this insert compatible with all DNMG holders?
Compatibility depends on the holder design; the DNMG150408 T9225 insert fits holders that accept ISO‑standard rhombic DNMG inserts with matching 55° geometry, plate thickness and fastening method.

Which materials suit the T9225 grade best?
The Tungaloy T9225 grade is intended for medium to heavy steel machining and performs well under varying engagement conditions and light interruptions.

Can the insert be indexed to use both cutting edges?
Yes, the insert is double‑sided; the DNMG150408 format allows indexation to present a fresh edge when the active edge is worn.

How does the 0.8 mm corner radius affect cutting?
A 0.8 mm corner radius increases edge strength and improves resistance to mechanical shock, supporting stable cuts and better surface finish in robust turning operations.

What system components are required for correct mounting?
A compatible external holder or boring bar, a support shim/clamping set and matching screws are required to secure the DNMG150408 Tungaloy insert properly.
