TNMG220408 T9225 — Indexable turning insert, CVD-coated carbide, Tungaloy

A TNMG220408 T9225 indexable insert designed for external and internal turning, offering reliable toughness for interrupted cuts and changing engagement conditions.

• CVD-coated carbide T9225 for tough cuts
• ISO TNMG220408 60° triangular form
• Double-sided chipbreaker for chip control
• 0.8 mm corner radius for versatile finishing

Stable machining under variable steel conditions

The insert’s CVD-coated carbide grade T9225 is formulated for robust, universal performance in medium to heavy steel turning, delivering improved toughness where interrupted cuts or variable engagement occur. The coating enhances wear resistance while the substrate maintains edge strength, which together reduce the frequency of tool changes and support a more predictable production rhythm. Compatibility with toolholders follows ISO standards, so replacement is straightforward when holders match the insert’s form, relief angle, tolerance class, fastening method, size and thickness.

Predictable chip control for efficient turning cycles

Equipped with a double-sided chipbreaker and a 0.8 mm corner radius, the insert ensures controlled chip formation and stable surface finishes in many turning operations. The chipbreaker geometry moderates chip flow for both external and internal turning, aiding swarf evacuation and reducing rework. For workshop planners, this means fewer interruptions and a smoother process chain, particularly when machining steels that demand a balance between edge toughness and cutting-edge stability.

Quick integration with ISO tooling systems

The TNMG220408 triangular form and 60° seating angle follow ISO conventions, which streamlines toolset-up and inventory management. The insert’s cylindrical hole and standard thickness of 4.76 mm permit simple clamping in compatible external holders or boring bars, while the standardised dimensions facilitate swift tool changes and consistent fixture behaviour. Operators and process engineers benefit from predictable assembly and inspection procedures, translating into shorter downtime during tool swaps.

Application-focused design for reliable workshop use

Designed as part of an ISO turning insert system, the component matches typical turning requirements: external and internal turning, variable cut stability and moderate interrupted cutting. The CVD-coated grade T9225 offers a broad workpiece material coverage for steel applications and supports effective surface quality with fewer regrinds. Where holders and clamping systems are correctly specified for form, relief angle and tolerance, the insert delivers repeatable results and contributes to overall process efficiency.

FAQ

What materials are suitable for this insert?
The TNMG220408 T9225 is intended primarily for steel machining and is a robust universal grade for medium to heavy steel turning, offering good performance under variable engagement.

Can the insert be used for both external and internal turning?
Yes. The triangular TNMG geometry and double-sided chipbreaker make the insert suitable for both external and internal turning operations.

How does the chipbreaker improve productivity?
The double-sided chipbreaker on the insert promotes controlled chip formation and evacuation, reducing interruptions and improving surface quality during continuous or slightly interrupted cuts.

Is this insert compatible with ISO tooling systems?
The insert follows ISO TNMG dimensions and mounts with a standard cylindrical hole; compatibility depends on matching the holder’s form, relief angle, tolerance class, fastening, size and thickness.

How many usable edges does the insert offer?
The triangular form provides multiple indexed cutting edges; the grade and double-sided chipbreaker support repeated indexing for extended tool life.
