TNMG 220412 T9225 turning indexable insert — Tungaloy, CVD‑coated carbide, 60°

TNMG220412 T9225 is an ISO‑standard triangular indexable insert designed for external and internal turning applications where a robust universal grade is required for medium to heavy steel machining

• CVD‑coated carbide grade T9225
• Universal for medium to heavy steel cutting
• Double‑sided chipbreaker, reversible insert
• 22 mm triangular insert with 1.2 mm radius

Consistent cutting performance for mixed conditions

The combination of a CVD‑coated carbide substrate and the T9225 grade delivers reliable toughness under changing engagement and slightly interrupted cut scenarios. This indexable insert is engineered to maintain a stable cutting edge, which reduces unexpected tool changes and supports predictable cycle times. The robust composition promotes stable chip formation and improves edge protection during moderate interruptions, yielding fewer rejects and more consistent surface quality.

ISO compatibility that simplifies tooling selection

Designed as an ISO‑standard insert, compatibility with holders is defined by form, relief angle, tolerance class, fastening method, size and thickness. The system approach — insert, matching outside holder or boring bar, backing/clamping set and replacement screws — enables straightforward swaps in production without requalifying the toolholder. Selecting the correct double‑sided chipbreaker and grade ensures the geometry matches the workpiece and the chosen machining strategy, helping to reduce setup time and increase throughput.

Geometry that balances strength and finish

The triangular shape with a 60° included angle and a 1.2 mm corner radius offers a balance between robustness and surface finish. With a plate thickness of 4.76 mm and a 0° clearance angle, the insert provides rigidity for deeper cuts while retaining the ability to produce acceptable finishes in medium‑ to heavy‑duty turning. The cylindrical hole and double‑sided format allow reversible mounting, extending usable life per insert and simplifying inventory management for high‑mix production environments.

Material and application advantages for reliable productivity

As a robust universal grade aimed at steel applications, the grade supports a wide range of turning tasks without frequent grade swaps. This versatility helps to lower tooling complexity in workshops processing varied steels. The insert’s construction is oriented toward stable performance rather than niche high‑speed extremes, which makes it a practical choice when process security, predictable tool life and repeatable component quality are priorities.

FAQ

What workpiece materials is this insert intended for?
The TNMG220412 T9225 indexable insert from Tungaloy is formulated as a robust universal grade particularly suited to medium to heavy steel turning operations.

How does the insert mount to a toolholder?
Compatibility is defined by the ISO form and the insert’s dimensions; the TNMG220412 fits holders that accept triangular ISO inserts with a cylindrical hole and the specified size, thickness and tolerance class.

Which geometrical features influence cutting behaviour?
The 60° included angle, 1.2 mm corner radius and 0° clearance combine to offer strength for heavier cuts while maintaining a surface finish suitable for many turning tasks.

Is the grade suitable for interrupted cuts?
Yes. The CVD‑coated carbide grade T9225 is designed with added toughness for variable engagement and light interruptions, providing more stable edge life under such conditions.
