TNMG 160408 T9225 ISO turning insert, CVD-coated carbide — Tungaloy

A TNMG 160408 T9225 indexable insert for ISO‑standard turning, engineered for medium to heavy steel machining and suited to both external and internal turning applications.

• CVD-coated carbide grade T9225
• For medium to heavy steel turning
• 60° triangular insert with 0.8 mm radius
• Double-sided chipbreaker with cylindrical hole

Consistent cutting performance for demanding steel operations

The T9225 grade is a CVD-coated carbide formulation designed to balance toughness and wear resistance, offering dependable performance under variable engagement conditions. In practice, this means fewer unexpected tool changes and a steadier machining process when facing interrupted cuts or fluctuating feeds. The coating supports abrasion resistance while the substrate maintains edge integrity, contributing to longer periods between indexing or replacement and thus improved overall productivity.

Predictable fit and quick setup across ISO tooling systems

Produced to ISO dimensions, the insert ensures compatibility with standard holders when matched for form, relief angle, tolerance class, fastening and thickness. The ISO conformity reduces setup uncertainty and enables predictable clamping behaviour, which translates to shorter machine downtime and consistent part quality. Selecting the correct holder geometry and clamping set minimises vibration and helps retain the insert’s cutting edge life under stable cutting conditions.

Geometry optimised for versatility and surface finish

The 60° triangular geometry with a 0.8 mm radius provides a practical compromise between strength and finish capability: the corner radius contributes to edge robustness for medium cuts while still permitting acceptable surface quality on finishing passes. The double-sided chipbreaker design extends usable edges per index and improves chip formation, aiding coolant flow and preventing material build-up. A cylindrical locating hole secures concentric clamping and supports repeatable positioning when indexing.

Practical application guidance for reliable results

Designed primarily for turning of steel components, this insert is best paired with a rigid holder, an appropriate shim or clamp set and the correct replacement screws to form the complete system. For stable setups and heavier cuts, choose tooling that minimises overhang and provides good vibration damping. Where interrupted cuts occur, the insert’s toughness and chipbreaker geometry help maintain process stability and reduce the risk of premature chipping or edge failure.

FAQ

What machining tasks is this insert suited for?
The TNMG 160408 T9225 indexable insert from Tungaloy is intended for external and internal turning, particularly for medium to heavy machining of steel where interrupted cuts or variable engagement demand increased toughness.

Which geometric features define the insert?
This insert has a 60° triangular shape with a 0.8 mm corner radius and a double-sided chipbreaker. The combination delivers a balance between edge strength and surface finish while allowing multiple indexings.

How does compatibility with toolholders work?
Compatibility depends on the ISO form, relief angle, tolerance class, fastening, size and thickness. The TNMG 160408 designation indicates ISO dimensions that fit standard external holders when the holder matches these parameters.

How many cutting edges are available per insert?
As a triangular, double-sided insert, the TNMG 160408 provides up to six usable cutting edges through indexing, which helps reduce tooling costs and changeover frequency.

What material and coating are used on this insert?
The insert is made of carbide with a CVD coating in the T9225 grade, engineered for robustness and stable chip formation in steel turning.
