TCMT 16T304 T9225 triangular turning insert, CVD-coated carbide — Tungaloy

The TCMT 16T304 T9225 is an ISO-standard triangular turning insert engineered for medium to heavy turning on steel where interrupted cuts and variable engagement demand toughness and consistent chip control.

• Robust CVD-coated carbide grade T9225
• ISO triangle form TCMT for versatile turning
• 0.4 mm corner radius for stable edge
• Designed for medium to heavy steel turning

High-performance grade for demanding steel turning

The combination of a CVD-coated surface and the T9225 carbide composition yields a robust, general-purpose grade developed for medium to heavy steel turning. The coating enhances thermal stability and wear resistance while preserving toughness for slightly interrupted cuts; this results in fewer insert changes and a higher productive machining window. For shops focused on throughput, the material pairing supports consistent tool life and stable chip formation, reducing unplanned downtime and improving process economy.

Geometry and clamping for repeatable accuracy

The triangular ISO geometry with a 60° included angle and a 0.4 mm corner radius provides a balanced compromise between strength and edge definition. The insert thickness of 3.97 mm and the 7° relief angle ensure secure seating in standard TCMT-compatible holders, while the central hole — presented as a cylindrical bore with a single-side countersink (40°–60°) — supports positive clamping and repeatable indexability. These features reduce vibration and improve surface finish during external and internal turning operations, helping to maintain dimensional accuracy across batch runs.

Process integration: chip control and system considerations

Selection of the appropriate chipbreaker and matching of the insert grade to the workpiece steel are decisive for optimised cycle times. The single-sided chipbreaker design included with this insert offers reliable chip control for typical turning tasks; pairing the insert with the correct external holder, shim or clamp set and replacement screws completes the system. The insert integrates into the ISO turning system architecture and is suitable for use with standard external holders or boring bars, enabling straightforward replacement and minimal setup time while supporting consistent part quality.

FAQ

What materials can this insert machine effectively?
The TCMT16T304 T9225 insert is intended primarily for steel machining; the T9225 grade provides robustness for medium to heavy steel turning and performs well under slightly interrupted cuts.

How does the T9225 grade differ from other carbide grades?
T9225 is a CVD-coated carbide grade optimised for a balance of toughness and wear resistance, offering improved process reliability in changing engagement conditions compared with harder, less tough grades.

Which holder features are required for correct clamping?
Correct clamping depends on holder form, clearance, tolerance class, fixation and plate size; the triangular TCMT geometry and the central cylindrical hole with countersink ensure positive seating in compatible TCMT holders.

Is this insert suitable for interrupted cuts and heavy engagement?
Yes, the grade and chipbreaker design of this insert make it suitable for interrupted cuts and heavier engagement typical in medium to heavy steel turning.
