TNMG220408 220408 T9225 turning insert — Tungaloy

A TNMG220408 T9225 indexable turning insert designed for medium to heavy steel turning, offering a robust universal grade and a triangular 60° geometry with a cylindrical hole for secure clamping.

• CVD-coated carbide for durability
• Universal T9225 grade for steel turning
• Double-sided chipbreaker for stability
• Triangular 60° form with cylindrical hole

Higher cutting reliability for steel turning operations

The insert is manufactured from CVD-coated carbide, a choice that balances wear resistance with toughness for heavy-duty conditions. The combination of the T9225 grade and the substrate material means stable cutting performance under varying engagement conditions, which reduces unexpected tool failures and machine downtime. For shops with mixed batches or interrupted cuts, this results in fewer insert changes and more predictable cycle times, improving overall process efficiency.

Consistent surface quality with optimised chip control

Equipped with a double-sided chipbreaker, the indexable plate promotes controlled chip formation and evacuation during both external and internal turning. The corner radius 0.8 mm contributes to stable cutting forces and a repeatable surface finish on steel components. Explaining briefly: chipbreakers modify the chip geometry so chips do not entangle or damage the workpiece, which is particularly beneficial when working with medium to heavy sections or when facing occasional interruptions in the cut.

Cost-effective indexing and secure clamping

The triangular, 60° geometry combined with a cylindrical hole allows for reliable seating in compatible tool holders and straightforward indexability—each insert offers multiple cutting edges for economical use. Compatibility with a holder depends on form, clearance angle, tolerance class, fastening and size; the insert’s 0° clearance and the standard ISO designation simplify selection for existing ISO-configured holders. As a result, workshops can maintain productivity with familiar clamping systems while benefiting from the insert’s robust performance.

Practical advantages for workshop planners and operators

This grade is engineered as a universal solution that performs across a broad range of steels, making inventory management simpler and reducing the number of specialised grades required. The insert’s double-sided nature and standardised ISO dimensions mean fewer reorders and quicker changeovers at the machine. For production teams, the clear technical specification supports predictable planning: known edge life, repeatable seating and reliable chip control enhance throughput and reduce scrap rates.

FAQ

What materials is this insert intended for?
The TNMG220408 T9225 insert is designed primarily for steel machining, with the T9225 grade optimised for medium to heavy steel turning.

How does the double-sided chipbreaker benefit production?
The double-sided chipbreaker on the Tungaloy TNMG220408 promotes controlled chip formation and safer evacuation, which reduces workpiece damage and improves surface consistency.

Is this insert compatible with ISO tool holders?
Yes; the TNMG220408 follows ISO indexable insert standards, but final compatibility requires matching the holder by form, clearance angle, tolerance class, fastening method and size.

How many cutting edges are available per insert?
As a double-sided triangular insert, the TNMG220408 provides multiple usable edges; indexing extends overall tool life and lowers per-edge cost.

Can this insert handle interrupted cuts?
The T9225 grade is formulated for robustness and increased toughness, making the insert suitable where light interruption or variable engagement occurs.
