TPMT090204 T9225 TPMT turning insert for turning by Tungaloy — CVD-coated carbide, 60° triangular shape

TPMT090204 T9225 is a robust ISO-format indexable insert designed for external and internal turning in medium to heavy steel applications, offering secure clamping via a central hole with a one-sided countersink.

• TPMT090204 60° triangular geometry
• CVD-coated cemented carbide T9225 grade
• One-sided chipbreaker for reliable chip control
• Central hole with 40°–60° countersink

Proven productivity in medium to heavy steel turning

The CVD-coated cemented carbide grade T9225 delivers a balanced combination of wear resistance and toughness that suits variable cutting conditions and light interruptions. The coating enhances flank and crater life, so machining runs remain productive over longer sequences. With the 0.4 mm nose radius and robust substrate, the insert supports both finishing and semi-roughing passes while keeping tooling costs under control through consistent edge life and predictable wear behaviour.

Stable chip control and edge reliability for intermittent cuts

The one-sided chipbreaker geometry is optimised for effective chip evacuation and to reduce built-up edge formation during tougher cuts. Paired with the 60° triangular shape, the insert provides multiple indexing positions, increasing usable edges per insert and lowering per-part tooling cost. The combination of geometry and substrate toughness makes this insert suitable where varying engagement or light interruptions occur, maintaining surface quality and dimensional stability.

Clear compatibility and secure clamping for workshop use

Supplied in the ISO format, the insert’s fit to a holder is defined by its form, 11° relief angle, tolerance class, fastening method, size and thickness. The centre hole is cylindrical with a one-sided countersink (40°–60°), allowing secure clamping with standard screws and locating pads. This configuration simplifies holder selection and ensures repeatable seating, which supports consistent cutting conditions across multiple insert changes and reduces setup variation.

Practical specifications that streamline tool planning

Key dimensions such as 2.38 mm thickness, size 09, and the 60° corner angle allow straightforward integration into standard external holders and boring bars. The insert’s ISO designation and consistent manufacturing tolerances make tool management simpler: spare inserts can be stocked with confidence and rotated as required to maximise value. Technical clarity on these parameters supports predictable process planning and efficient inventory control.

FAQ

What materials is this insert suitable for?
The TPMT090204 T9225 turning insert is developed for medium to heavy steel machining where toughness and wear resistance are required; the T9225 grade balances both properties for robust performance.

How does the central hole affect clamping?
The central cylindrical hole with a one-sided countersink (40°–60°) on the TPMT090204 enables secure seating in standard holders and ensures repeatable clamping for stable turning operations.

How many usable edges does the triangular insert provide?
The 60° triangular shape offers multiple indexing positions; each corner can be indexed to present a fresh cutting edge, maximising the number of usable edges per insert.

Is the insert suitable for interrupted cuts?
Yes. The CVD-coated T9225 grade and the insert’s geometry provide enhanced toughness and chip control, making it appropriate for slightly interrupted or variable engagement conditions.

Which holder types are compatible with this ISO insert?
Compatibility is determined by the insert form, relief angle, tolerance class, fastening and size; the TPMT090204 fits standard external holders and boring bars designed for ISO triangular inserts.
