TNMG220416 T9225 TNMG turning insert, CVD‑coated carbide, 60° triangle (Tungaloy)

The TNMG220416 T9225 is an ISO‑standard triangular turning insert designed for external and internal turning of steel, offering a universal, robust grade for variable cutting conditions.

• TNMG220416 geometry for ISO turning
• CVD-coated carbide grade T9225 for robustness
• Double-sided chipbreaker for versatile cutting
• 1.6 mm corner radius for stable engagement

Durable grade and coating for demanding steel work

The insert combines a CVD‑coated surface with a carbide substrate and the T9225 specification to deliver enhanced wear resistance and greater toughness under variable engagement conditions. This engineered pairing reduces flank wear during prolonged runs and favours process stability when machining medium‑to‑heavy steel; the coating improves thermal stability and lowers adhesive wear in wet and dry turning alike. For production environments where cutting conditions change or where slight interruptions occur, the composition of the grade is intended to extend effective tool life while maintaining dimensional quality.

Geometry and chip control that stabilise cutting performance

The triangular plate with a 60° cutting angle and a 1.6 mm corner radius provides a balance between strength and accessibility, enabling secure entry and reduced vibration on heavier cuts. The double‑sided chipbreaker actively manages chip flow and cutting forces, which aids in maintaining consistent surface finish and reduces the risk of re‑cutting. A cylindrical hole ensures secure clamping in compatible holders, while the plate thickness (4.76 mm) and 22 mm size contribute to stable clamping and repeatable positioning. These geometric decisions translate into fewer interruptions for re‑indexing and improved uptime on the machining centre.

Practical system guidance and application notes

This insert is intended for use within an ISO turning system consisting of an appropriate external holder or boring bar, a shim or clamping set and replacement fastening screws. Holder compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness; selecting the correct chipbreaker and matching the T9225 grade to workpiece stability is essential for optimised productivity. Typical use covers both external and internal turning operations on steel where a combination of strength and fracture resistance is required. For customers seeking process security and repeatable results, the insert’s design supports predictable tool change intervals and consistent part quality.

FAQ

Which holders are compatible with this TNMG variant?
Compatibility depends on the holder form, clearance angle, tolerance class, fastening method, size and thickness; the TNMG220416 T9225 fits ISO‑standard holders designed for TNMG inserts when those parameters match.

What materials can be machined with this insert?
The T9225 grade is formulated for medium‑to‑heavy steel machining and performs well where toughness is required under varying engagement or slightly interrupted cuts.

Is the insert suitable for interrupted cutting?
Yes, the combination of the T9225 grade and the triangular geometry with a 1.6 mm corner radius improves resistance to impact and supports interrupted cutting scenarios.

How does the chipbreaker affect cutting?
The double‑sided chipbreaker directs chips and controls cutting forces, which helps maintain surface finish and reduces the likelihood of chip re‑entanglement on the workpiece.

What components form the complete turning system for this insert?
A complete system typically comprises the insert, a matching external holder or boring bar, a shim/clamping set and the appropriate replacement screws for secure fastening.
