DCMT 11T304 T9225 Tungaloy indexable insert – ISO turning insert, 55° rhombic, 0.4 mm radius

The DCMT11T304 Tungaloy indexable insert is an ISO‑format turning insert designed for external and internal turning, offering a universal grade for medium to heavy steel machining.

• CVD‑coated carbide T9225 for robustness and wear resistance
• ISO DCMT form, 55° rhombic geometry
• 0.4 mm nose radius for general turning tasks
• Single‑sided chipbreaker for stable chip control

Consistent cutting performance in mixed conditions

The CVD‑coated T9225 grade combines wear resistance with sufficient toughness for when cutting conditions vary or the cut is slightly interrupted. This composition delivers stable chip formation and predictable tool life, reducing unplanned tool changes and improving production continuity. The insert’s design supports a broad range of steel workpieces, making it a solid choice where a balance of durability and performance is required.

Geometry that supports accuracy and surface finish

The rhombic 55° form and a 0.4 mm nose radius provide a compromise between strength and finishing capability, enabling good surface results on external and internal profiles. A 7° relief angle and a plate thickness of 3.97 mm ensure rigidity in the cutting zone, while the cylindrical hole with a one‑sided countersink (40°–60°) guarantees secure seating in compatible clamping systems. These geometric details translate into repeatable cuts and reduced vibration for more consistent tolerances.

System compatibility and straightforward mounting

As an ISO‑standard indexable plate, compatibility with holders is determined by form, relief angle, tolerance class, fixing method, size and thickness. The typical system comprises an ISO DCMT insert, a matching external holder or boring bar, a shim/clamp set and replacement screws. Specifying the correct holder and clamp reduces setup time and minimises the risk of incorrect seating, supporting efficient tool changes and lower machine downtime.

Practical benefits for workshop productivity

With its single‑sided chipbreaker and universal grade chemistry, the insert is suitable for a wide range of turning tasks, from general roughing to semi‑finishing in steel. The Tungaloy grade offers a robust option where changing engagement conditions occur, delivering fewer insert breakages under intermittent cuts. Choosing ISO‑conforming inserts simplifies stockkeeping and allows rapid replacement across different machines and fixtures, helping to maintain steady throughput.

FAQ

What workpieces is this insert best suited for?
The DCMT11T304 Tungaloy indexable insert in grade T9225 is intended primarily for medium to heavy steel turning where varying engagement conditions or light interruptions require increased toughness.

How does the T9225 grade affect tool life?
T9225 is a CVD‑coated carbide grade that balances wear resistance and toughness, which helps to extend service life under mixed or interrupted cutting conditions when using the DCMT11T304 insert.

Is the insert compatible with standard ISO holders?
Yes, the insert follows ISO DCMT geometry; compatibility depends on matching form, relief angle, tolerance class, fixing method, size and thickness to the holder.

Can this insert be used for finishing operations?
With a 0.4 mm nose radius and 55° rhombic geometry, the insert supports semi‑finishing and general finishing tasks, though fine finishing may call for smaller nose radii or alternative grades.

What mounting features ensure secure clamping?
The cylindrical hole with a one‑sided countersink (40°–60°) provides positive seating and stable clamping when used with the correct shim and clamp set in the matching holder.
