TNMG 220408 T9205 indexable turning insert for Turning – Tungaloy

A TNMG220408 T9205 indexable insert engineered for productive external and internal turning of steel under stable cutting conditions.

• CVD-coated carbide grade T9205
• Designed for productive steel turning
• Double-sided chipbreaker for stability
• ISO TNMG 220408, 0.8 mm corner radius

Maximise cutting performance with a wear-resistant coating

The CVD-coated cemented carbide composition of this grade provides a clear advantage for workshops seeking consistent performance at higher cutting speeds. The T9205 formulation is tuned for abrasive resistance and stable edge life during medium- to high-speed turning of steel, translating into fewer indexings and longer periods between tool changes. For production environments, this means improved cycle times and reduced tooling overhead while maintaining dimensional consistency across batches.

Precise ISO geometry for predictable set-up and interchangeability

The insert follows the ISO TNMG 220408 geometry with a triangular form and a principal angle of 60°, supplying a standardised interface to established holder systems. With a plate thickness of 4.76 mm, a corner radius of 0.8 mm and a 0° clearance angle, the geometry ensures predictable cutting forces and stability when paired with a correctly matched external holder and clamping kit. Compatibility is determined by shape, clearance angle, tolerance class, fastening type, size and thickness, so selecting an ISO-compliant holder avoids unnecessary rework and shortens set-up times when changing inserts.

Improved chip control and surface quality under stable conditions

Equipped with a double-sided chipbreaker, this insert supports secure chip formation and evacuation during continuous turning operations. The chipbreaker design helps to maintain a controlled chip shape, reduce tendency to clogging and contribute to a consistent surface finish. In practice, choosing the appropriate chipbreaker and grade for the workpiece material and process stability substantially lowers the risk of built-up edge and promotes repeatable part quality on both external and internal turning tasks.

System-level benefits and economical process design

Used as part of a complete ISO insert system — comprising the insert, a compatible external holder or boring bar, a support piece/clamping set and spare screws — this grade promotes efficient production planning. The T9205 coating and substrate combination supports longer tool life and reliable edge integrity, which benefits batch processing and makes cost-per-part more competitive. The result is a balance of durability and machining productivity that suits job shops and production lines aiming for reproducible results with minimal process disturbance.

FAQ

Which materials is this insert optimised for?
The insert is specified as a wear-resistant T9205 grade and is optimised for productive turning of steel, benefitting from the CVD-coated carbide to withstand abrasive conditions typical in steel machining.

What are the key geometric characteristics of the insert?
The TNMG 220408 insert has a triangular form with a 60° principal angle, a corner radius of 0.8 mm, a plate thickness of 4.76 mm and a 0° clearance angle, providing standard ISO dimensions for predictable holder compatibility.

Can the insert be indexed or reversed during use?
Yes, the insert is double-sided and indexable; the double-sided chipbreaker allows reversal or indexing to a fresh cutting edge, extending usable life before replacement.

How does the CVD coating affect performance?
The CVD coating on the cemented carbide substrate enhances wear resistance and preserves the cutting edge at elevated cutting speeds, which supports longer tool life and stable performance in continuous turning operations.

Which holder types are suitable for this insert?
Holders compliant with ISO TNMG 220408 geometry and matching the insert’s shape, clearance angle, tolerance class, fastening and thickness are suitable; correct selection of an external holder or boring bar ensures stability and repeatable clamping.
