TCMT16T304 T9225 ISO triangular turning insert by Tungaloy — 60° geometry, CVD-coated grade

TCMT16T304 T9225 is an ISO‑standard triangular indexable insert designed for external and internal turning, optimised for medium to heavy steel machining where toughness and stable chip formation are required

• ISO triangular insert, 60° geometry
• CVD-coated carbide grade T9225
• 0.4 mm corner radius for robust profiles
• Compatible with standard ISO turning holders

Proven cutting performance for heavy-duty steel turning

The CVD-coated carbide composition and the designated T9225 grade combine hardness and toughness to sustain cutting forces during medium-to-heavy steel machining. The insert’s 0.4 mm corner radius improves edge strength and reduces chipping risk under variable engagement, meaning longer effective tool life and fewer unplanned indexings. The ISO-conformant form ensures reproducible clamping and predictable cutting results; in practice, this leads to stable cycle times and a lower overall cost per part when compared with less specialised grades. For interrupted cuts or changing entry angles the insert provides the resilience required to maintain dimensional accuracy.

System compatibility and mounting advantages for workshop planning

Compatibility is defined by insert shape, 7° clearance angle, tolerance class, fastening style, size and thickness. The triangular 60° form makes the component suitable for common ISO holders, while the cylindrical hole with single‑side countersink (40°–60°) supports secure fixation with standard screws. The nominal 3.97 mm thickness gives adequate support in heavy engagement, and the triangular shape offers three usable cutting edges, improving cost efficiency per edge. When organising tooling kits, include the correct holder, shim or clamping set and spare screws to ensure immediate replacement and minimal machine downtime.

Practical machining benefits and process guidance

The single‑sided chipbreaker is designed to assist with chip control when turning steel at medium to high uncut chip thicknesses; smoother evacuation reduces rework and shortens cycle times. The insert’s toughness is an advantage where cuts are slightly interrupted or where part clamping causes variable cutting conditions. Selection of feeds and speeds should reflect the workpiece material and machine rigidity: higher stiffness and correct feed will exploit the grade’s wear resistance, while moderate cutting speeds extend edge life. In short, a robust insert specification simplifies process planning and helps achieve repeatable component quality.

FAQ

Is this insert suitable for interrupted cuts?
The TCMT16T304 T9225 insert is specified for robustness and toughness; the CVD-coated carbide grade is intended to handle slight interruptions and variable engagement common in steel turning.

What holders are compatible with this triangular insert?
Compatibility depends on the ISO triangular form and dimensions; the insert fits standard ISO turning holders designed for TCMT 16 sized inserts with a 60° geometry.

How many cutting edges are available per insert?
The triangular design provides three indexable cutting edges; correct indexing extends tool utilisation and lowers cost per edge.

What machining benefits does the T9225 grade provide?
T9225 offers a balanced combination of toughness and wear resistance, improving edge stability under medium-to-heavy machining of steel and aiding consistent surface quality.

Does the insert have a central mounting hole and countersink?
Yes, the insert features a cylindrical hole with a single-sided countersink (40°–60°) for secure screw fixation and repeatable clamping.
