DCMT 070202 T9225 turning insert by Tungaloy — CVD-coated carbide, rhombic ISO insert

The DCMT070202 T9225 is an ISO rhombic turning insert designed for external and internal turning where toughness and stable cutting performance are required.

• ISO rhombic insert DCMT070202
• CVD-coated carbide grade T9225
• 7° clearance for secure chip control
• Cylindrical hole with single-side countersink

Consistent cutting performance for medium to heavy steel

The combination of CVD-coated carbide and the robust T9225 grade provides a dependable balance of wear resistance and toughness, making the insert suitable for variable engagement and slightly interrupted cuts. This formulation reduces flank wear and extends edge life, which translates into fewer tool changes and improved productivity in series turning. The rhombic geometry and ISO conformity ensure predictable cutting behaviour across standard tool holders.

Straightforward system compatibility and faster setup

Designed as an ISO turning insert, the item matches holders by form, clearance angle, tolerance class, fastening, size and thickness. The standardised format simplifies tool selection for workshops that use ISO tooling systems, shortening machine downtime during tool changes. The insert’s 07 size and secure central hole with single‑side countersink help achieve repeatable clamping and concentricity, contributing to consistent part quality across runs.

Controlled chip formation and surface quality

The single‑sided chipbreaker and the 0.2 mm nose radius combine to produce predictable chips and a balanced surface finish when machining steel. The small corner radius supports good edge strength while aiding fine surface results on external profiles and bore finishes. Choosing the appropriate chipbreaker and feed rate for the workpiece stability yields a measurable improvement in component consistency and reduces rework.

Practical guidance for setup and application

Use the insert together with a compatible external holder or boring bar, plus a suitable shim and clamping set; spare screws should be kept available to avoid unplanned interruptions. Match the insert geometry and the T9225 grade to the workpiece material and the machine’s rigidity: prioritise stability for heavier cuts and select lighter engagement for finishing passes. Regularly check clamping torque and seating to preserve repeatable accuracy and maximise service life. If the machining conditions are uncertain, use the universal grade for its wider material coverage.

FAQ

What materials is this insert best suited for?
The DCMT070202 insert with Tungaloy’s T9225 grade is designed primarily for steel machining, offering a universal solution for medium to heavy steel turning.

How does the insert ensure stable clamping?
The rhombic form with a cylindrical hole and single‑side countersink provides stable seating and clamping repeatability when used with the appropriate ISO external holder and clamping set.

Can the insert handle interrupted cuts?
Yes, the T9225 grade and CVD coating deliver the toughness required for slightly interrupted cuts and variable engagement conditions common in turning operations.

What surface finish can be expected with a 0.2 mm radius?
A 0.2 mm corner radius supports a good compromise between edge strength and finish quality; it sustains load during heavier passes while enabling acceptable surface results on finishing passes.

Which system components should accompany the insert?
A suitable external holder or boring bar, a matching shim/clamping set and replacement screws are recommended to ensure correct seating and repeatable performance with the DCMT070202 insert.
