DPMT11T302 T9225 — ISO indexable turning insert (DPMT 11T302) for turning, CVD‑coated carbide (Tungaloy)

DPMT11T302 T9225 is an ISO‑standard rhombic indexable insert designed for external and internal turning in demanding steel applications, providing a balance of toughness and wear resistance for varying engagement conditions.

• CVD-coated carbide grade T9225
• ISO DPMT rhombic insert, 55° included angle
• 0.2 mm nose radius for precise finishes
• Suitable for medium to heavy steel turning

Stable chip control for predictable cycle times

The CVD‑coated carbide grade T9225 delivers a combination of wear resistance and toughness that supports consistent chip control during longer production runs. With a one‑sided chipbreaker tailored to the application, the insert reduces the risk of long, stringy chips and helps maintain steady machining cycles. This results in fewer unscheduled interruptions and a more efficient use of machine time, which is particularly relevant when process reliability and throughput are primary objectives.

Geometry that secures surface quality and repeatability

The rhombic ISO DPMT shape and 55° included angle provide stable seating in common toolholders, while the 0.2 mm nose radius and 11° relief angle support fine surface finishes and tight dimensional tolerance on turned parts. Compatibility with a holder is determined by shape, clearance angle, tolerance class, fastening, size and thickness; correct pairing with an appropriate clamping set or shim ensures repeatable mounting and consistent results across inserts. The ISO standardisation simplifies tool selection and inventory management for production shops.

Built for interrupted cuts and variable engagement

This insert is specified as a robust universal grade, making it suitable where engagement conditions vary or slightly interrupted cuts occur. The substrate and coating combination provide the additional toughness required under changing loads, which helps prevent premature chipping at the cutting edge and extends in‑process reliability. For workshops facing mixed batch work or imperfect clamping conditions, the grade reduces the need for frequent tool replacement and supports steady component quality.

Practical system integration and safe fastening

The insert is supplied as an ISO‑standard plate that forms part of a system: a matching external holder or boring bar, underlay/clamping set and replacement screws complete the assembly. It is produced with a cylindrical hole and a single‑sided countersink (40°–60°) to suit common fastening conventions, and its rhombic form ensures predictable orientation in indexed toolholders. When selecting a chipbreaker and grade, match the option to workpiece material, machining type and machine stability to gain the full benefit of the insert’s performance characteristics.

FAQ

What applications suit this insert best?
The insert is intended for turning operations, particularly external and internal turning where medium to heavy steel machining is required; the T9225 grade offers toughness for changing engagement conditions.

Is this insert compatible with standard ISO holders?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; the rhombic ISO DPMT geometry ensures fitment with matching ISO‑compliant toolholders.

Can the insert handle slightly interrupted cuts?
Yes. The robust universal grade and CVD coating of this insert are specified to tolerate slightly interrupted cuts and variable engagement without rapid edge failure.

How does the hole design affect clamping?
The cylindrical hole with a single‑sided countersink (40°–60°) provides secure fastening in common clamping systems and simplifies replacement of screws and underlay components.

How should the chipbreaker and grade be selected?
Choose the chipbreaker and the T9225 grade according to the workpiece material, the machining type (roughing or finishing) and machine stability to achieve optimal chip control and tool life.
