TNMG 160408 T9225 – TNMG160408 T9225 Tungaloy turning insert (CVD-coated carbide, 0.8 mm radius)

TNMG160408 T9225 is an ISO-standard triangular indexable insert designed for turning in varying engagement conditions and interrupted cuts

• CVD-coated carbide grade T9225
• Designed for medium to heavy steel machining
• ISO TNMG160408 triangular insert, 0° clearance
• Double-sided chipbreaker with cylindrical hole

Durable coating and material engineered for productivity

The combination of a CVD-coated surface and a carbide substrate in grade T9225 delivers a balance of wear resistance and toughness optimised for medium to heavy steel turning. The CVD process forms a hard, adherent layer that reduces flank wear and thermal degradation during sustained cuts, while the substrate beneath provides impact resistance where variable engagement or light interruptions occur. The insert’s 0.8 mm corner radius and 4.76 mm thickness contribute to edge strength and vibration dampening, which helps maintain consistent surface finish and reduces the need for frequent edge changes.

ISO compatibility and system-level advantages

As an ISO-standard insert, the TNMG160408 designation denotes a triangular geometry with a 60° included angle suitable for a wide range of turning holders. Compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness; matching the insert to the correct holder, shim and clamping set ensures secure mounting and accurate repeatability. The double-sided chipbreaker and cylindrical hole enable reliable indexing and clamping, allowing multiple usable cutting positions and straightforward rotation or replacement without special adapters. This system approach supports shorter setup times and higher process stability.

Applicability in production and cost-efficiency

Primarily intended for external and internal turning of steel components, the insert’s robust design supports productive machining strategies where tool life and consistent chip control matter. The T9225 grade is a universal, wear-resistant choice for workshops facing mixed batch sizes and varying cut conditions; when cutting parameters are optimised, the result is improved cycle times and fewer tool changes. For operations seeking process reliability, selecting a matching chipbreaker and the correct insert geometry can reduce downtime and contribute to predictable, repeatable output—benefits that translate into measurable production efficiency.
