TCMT090204 T9225 ISO triangular turning insert — CVD‑coated carbide by Tungaloy

The TCMT090204 T9225 is an ISO‑standard triangular turning insert engineered for medium‑to‑heavy steel turning where variable engagement and slight interruptions demand increased toughness and consistent chip control.

• ISO triangular insert TCMT 09 size, 7° relief
• CVD‑coated carbide grade T9225 for medium–heavy steel
• 0.4 mm corner radius for reliable edge strength
• Cylindrical hole with countersink for secure clamping

Built for consistent metal removal and extended edge life

The combination of a CVD‑coated surface and a robust carbide substrate provides a resilient cutting edge that balances wear resistance with toughness. The T9225 grade is formulated for medium‑to‑heavy steel machining and is particularly suitable where changing entry conditions or slightly interrupted cuts occur; this supports stable chip formation and predictable tool life under mixed conditions. As an ISO‑compliant indexable solution, the insert supports efficient production workflows by allowing quick indexing and replacement, reducing machine downtime and improving process repeatability.

Secure clamping and efficient indexing for stable performance

The triangular geometry offers three usable cutting edges per insert, improving economy per edge while maintaining good rigidity. The insert thickness of 2.38 mm, the 7° relief angle and the 60° included angle give clear guidance for compatible clamping and holder selection. The central feature — a cylindrical hole with a one‑sided countersink (40°–60°) — enables reliable seating and torque transmission in standard clamping systems. These mechanical details translate into stable clamping, reduced risk of rotation under load and consistent cutting geometries that help achieve repeatable surface quality.

Practical selection advice to match process requirements

Selection should follow the ISO system logic: holder compatibility is determined by insert form, relief angle, tolerance class, fastening method, size and thickness. Choose a matching chipbreaker and the T9225 grade for applications where toughness is required across a wide range of steels; select a finer radius or different geometry if a smoother finish or lighter cuts are the priority. The insert is supplied as part of an ISO system — insert, suitable outer holder or boring bar, shim/clamping set and replacement screws — which simplifies ordering and integration into existing toolsets. For application guidance or material‑specific recommendations, technical consultation is available to ensure the most economical and productive configuration.

FAQ

Is this insert suitable for interrupted cutting in steel?
Yes. The T9225 grade and the TCMT090204 geometry are designed for medium‑to‑heavy steel turning where occasional interruptions or variable engagement require higher toughness.

Which toolholders are compatible with this insert?
Compatibility follows ISO standards: form, relief angle (7°), tolerance class, fastening method, size (09) and thickness (2.38 mm) determine suitable outer holders and boring bars for the insert.

How many cutting edges are available per insert?
The triangular TCMT indexable insert provides three cutting edges, allowing efficient indexing and cost‑effective use of each insert.

What does the central hole and countersink provide?
The cylindrical hole with a one‑sided countersink (40°–60°) ensures secure seating and reliable clamping torque transfer, improving stability during heavy cuts and reducing the risk of insert rotation.

For which materials is the grade T9225 recommended?
T9225 is a robust, universal CVD‑coated carbide grade suited to a wide range of steels, particularly for medium‑to‑heavy machining tasks and operations with changing entry conditions.
