DCMT 11T304 T9225 Tungaloy indexable insert — ISO turning insert, CVD-coated carbide

The DCMT11T304 is an ISO rhombic indexable insert designed for robust turning applications, optimised for varying engagement and lightly interrupted cuts in steel.

• DCMT11T304 insert, T9225 CVD-coated carbide
• 55° rhombic shape with 0.4 mm corner radius
• Suitable for medium to heavy steel turning
• Cylindrical hole with one-sided countersink

Reliable cutting performance for variable engagement

The T9225 grade is a CVD-coated carbide designed as a robust universal option for medium to heavy steel machining. Its composition prioritises toughness for changing cutting forces and lightly interrupted cuts, which reduces edge chipping and downtime. The result is predictable tool life and consistent cycle times, making this insert a practical choice where process stability and component repeatability are essential.

Geometry and coating that improve productivity

A 55° rhombic outline combined with a 0.4 mm corner radius provides a compromise between edge strength and surface finish: the small radius supports durable edges at higher feeds while still delivering acceptable finishes on external profiles. The CVD-coated layer increases wear resistance at elevated temperatures and supports extended runtimes under heavy loading, helping to maintain dimensional accuracy over longer production runs.

Clear guidance on compatibility and secure clamping

Compatibility with a holder is governed by form, clearance angle 7°, tolerance class, fixing method, size and thickness. The insert is an ISO indexable component intended for use with a matching external holder or boring bar, plus an underlay/clamping set and replacement screws for secure assembly. The plate includes a cylindrical hole with a one-sided countersink (40°–60°), ensuring positive positioning and repeatable clamping in standard ISO systems.

Practical selection and application tips

Choose the single-sided chipbreaker variant and the T9225 grade when workpieces are steel and conditions include moderate interruptions or variable engagement. For fine finishing or very high-speed turning, consider a smaller feed or alternating to a finer radius; for roughing increase feed and monitor cutting forces. This insert suits both external and internal turning tasks where robustness and versatile performance are required.

FAQ

What materials is this insert suitable for? The DCMT11T304 in T9225 is intended primarily for steel work, offering a robust option for medium to heavy steel turning with good tolerance to variable cutting conditions.

How does the T9225 grade behave under interrupted cuts? Tungaloy's T9225 grade combines toughness and wear resistance so that the insert resists chipping under lightly interrupted cuts, maintaining tool life and process stability.

Which holders are compatible with this ISO insert? Compatibility depends on the holder matching the insert form, 7° clearance angle, tolerance class, fixing method, size and thickness; use a suitably rated ISO external holder or boring bar with the correct clamping kit.

What effect does the 0.4 mm corner radius have? A 0.4 mm radius increases edge strength for heavier cuts and reduces the risk of fracture while still allowing acceptable surface finish compared with larger radii used for roughing.

Is the insert supplied with screws or clamping hardware? The insert is part of an ISO system that typically comprises the insert, matching holder/boring bar, underlay/clamping set and replacement screws; consult Metav Werkzeuge for the correct clamping components.
