DNMG 110402 T9225 turning insert by Tungaloy — CVD-coated carbide, rhombic 55° geometry

DNMG110402 T9225 is a rhombic, ISO-format turning insert engineered for external and internal turning operations where a robust universal grade is required

• CVD-coated carbide T9225 universal grade
• 55° rhombic shape for versatile clamping
• Double-sided chipbreaker for stable chips
• 0.2 mm corner radius for fine finishing

Longer tool life and predictable performance for medium to heavy steel turning

The CVD-coated carbide composition and the T9225 grade provide a deliberate balance between wear resistance and toughness, making this insert suitable for medium to heavy steel machining and transient engagement conditions. CVD (chemical vapour deposition) produces a hard, wear-resistant surface layer that reduces flank and crater wear, while the carbide substrate absorbs cutting shocks. The result is consistent tool life under mixed cutting conditions and reduced downtime through fewer insert changes.

Geometry that delivers repeatable accuracy and secure clamping

A 55° rhombic geometry combined with a 0° clearance angle and a cylindrical hole ensures reliable seat and repeatable register in compatible holders. The standardised ISO form and the specified dimensions — 11 mm size and 4.76 mm thickness — mean interchangeability across ISO-compatible systems. Compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness, so selecting the correct holder and clamping set keeps the cutting edge stable and the workpiece finish consistent.

Improved productivity through controlled chip formation

The double-sided chipbreaker and the inserted chip control features promote stable chip formation across varying depths of cut. Stable chips reduce the risk of re-cutting and protect the machined surface, which helps to shorten cycle times and lowers rework rates. Using this insert in an appropriate holder and with matching cutting conditions enables efficient material removal while maintaining surface quality.

System-level clarity and application guidance

This insert is supplied as part of an ISO turn­ing insert system: ISO-format insert, matching external holder or boring bar, shim/clamping set and spare screws. For turning and internal operations, choose the chipbreaker and grade that correspond to the workpiece material and machine stability. The 0.2 mm corner radius is suitable for fine finishing and semi-finishing; larger radii are recommended where higher strength at the nose is required. For interrupted cuts or unstable set-ups, the T9225 grade offers additional toughness to withstand shock loads.

FAQ

What materials is this insert suited for?
The DNMG110402 T9225 turning insert is designed primarily for steel machining, covering medium to heavy-duty turning where toughness and wear resistance are required.

Can the insert handle interrupted cuts?
Yes. The T9225 grade provides added toughness suitable for slightly interrupted cuts and changing engagement conditions.

How does the chipbreaker influence surface finish?
A properly matched double-sided chipbreaker promotes controlled chip evacuation, which helps to protect the machined surface and contributes to a consistent finish when combined with correct cutting parameters.

Which holder type is compatible with this insert?
Compatibility depends on form, clearance angle, tolerance class, fastening, size and thickness; the 55° rhombic form fits standard ISO holders designed for DNMG-style inserts.

Is this insert reversible or indexable?
The insert is double-sided and indexable, enabling multiple cutting edges per insert to improve economy and reduce tool change frequency.
