TPMT 090202 T9225 triangle indexable insert — CVD-coated carbide, 11° clearance (Tungaloy)

TPMT090202 T9225 is an ISO‑compliant triangular insert designed for external and internal turning; a robust universal grade for medium to heavy steel machining.

• CVD-coated carbide for robust performance
• T9225 grade for medium to heavy steel machining
• 60° triangular form with 0.2 mm corner radius
• Central hole with cylindrical bore and countersink

Reliable cutting performance for variable engagement

The CVD-coated carbide substrate and the T9225 robust universal grade deliver a good balance of toughness and wear resistance, especially where cutting conditions vary or cuts are slightly interrupted. This composition reduces the risk of chipping under moderate impact while maintaining an economically attractive tool life. The result is more predictable tool change intervals and stable surface finish during continuous turning operations on steel workpieces.

Precision geometry to secure clamping and consistent chip formation

A defined 11° clearance and the 60° triangular form ensure reproducible contact with standard ISO triangular tool holders, while the 0.2 mm corner radius provides controlled edge strength for finishing and light roughing passes. The insert features a central hole with a cylindrical bore and a one‑sided countersink (40°–60°), enabling positive clamping and minimising insert movement under load. These geometric cues help to maintain cutting consistency across batches and simplify insert indexing.

System-level reliability for productive turning processes

As part of an ISO indexable insert system, the plate integrates with matching holders, underplates and screws to create a secure cutting assembly. The single‑sided chipbreaker is optimised for common steel machining tasks, supporting efficient chip control and evacuation. Selection of the correct holder and clamping torque is essential to exploit the grade’s advantages; the insert’s universal character keeps inventory lean while supporting a range of turning operations from finishing to heavier cuts.

FAQ

What workpieces is this insert best suited for?
The TPMT090202 T9225 insert is designed primarily for medium to heavy machining of steel; the T9225 grade provides toughness for variable engagement and interrupted cuts.

Which holder types are compatible with this triangular plate?
Compatibility depends on holder form, relief angle, tolerance class, clamping method, size and thickness; the TPMT090202 fits ISO triangular holders with matching mounting geometry.

How does the central hole and countersink affect clamping?
The central hole with cylindrical bore and one‑sided countersink (40°–60°) enables secure, repeatable clamping and helps to prevent insert rotation during turning operations.

Is the chipbreaker suitable for finishing passes?
The one‑sided chipbreaker is optimised for steel turning and supports both finishing and medium roughing when combined with appropriate feeds and speeds.

Can the same insert be used for internal and external turning?
Yes; the ISO triangular form and universal T9225 grade allow the insert to be used for both internal and external turning, subject to toolholder and machine setup.
