DCMT 11T302 T9225 — ISO rhombic turning insert for medium-to-heavy steel (Tungaloy)

DCMT11T302 T9225 is an ISO-format rhombic indexable insert intended for external and internal turning; the insert integrates a 55° cutting geometry, a 0.2 mm corner radius and a CVD-coated carbide grade optimised for interrupted and variable cutting conditions.

• ISO rhombic insert with 55° cutting angle
• CVD-coated carbide grade T9225
• 0.2 mm corner radius for precise finishing
• Single-sided chipbreaker; cylindrical hole

Consistent performance where conditions vary

The combination of a CVD-coated carbide substrate and the T9225 grade delivers a balance of toughness and wear resistance that suits medium-to-heavy steel machining under variable engagement. The coating enhances thermal stability and reduces flank wear, which translates into longer edge life and fewer insert changes. Selecting this insert supports a stable process and improves machining uptime through predictable tool behaviour, especially when cuts are slightly interrupted or when rigidity fluctuates.

Secure clamping and straightforward holder compatibility

Designed to ISO dimensions, the rhombic insert fits standard indexable turning holders whose compatibility is determined by insert form, relief angle and tolerance. The insert’s cylindrical hole with one-sided countersink (40°–60°) and a nominal thickness of 3.97 mm provide reliable seating and repeatable clamping. This secure fixation reduces micro-movements at the cutting edge, improving dimensional repeatability and surface finish with each indexed position.

Practical benefits for shop-floor decisions

With a 0.2 mm corner radius and single-sided chipbreaker, the insert offers a compromise between finishing quality and robustness. The small radius supports fine surface finishing without sacrificing strength, while the chipbreaker assists in breaking and evacuating chips efficiently in standard turning tasks. For production environments where tool changes affect cycle time, this insert lowers the frequency of replacements and helps maintain consistent part quality.

Material suitability and application advice

The insert is specified for turning applications and is particularly suitable for a wide range of steels thanks to its robust universal grade that tolerates changing cutting conditions. Typical uses include external and internal turning operations where a reliable chip control and a stable cutting edge are required. For best results, pair the insert with a matching ISO rhombic holder and choose cutting parameters that reflect the workpiece material and machine rigidity.

FAQ

What materials is this insert best suited for?
The DCMT11T302 T9225 insert is optimised for medium-to-heavy steel machining; the T9225 grade and CVD coating provide the toughness and wear resistance required for such applications.

How does the 0.2 mm corner radius affect part finish?
A 0.2 mm corner radius offers a fine balance between surface quality and edge strength, enabling improved finishes while maintaining resistance to chipping during turning operations.

Is the insert compatible with standard ISO holders?
Yes, the insert follows ISO rhombic dimensions (11T302) so compatibility depends on holder form, relief angle and tolerance class; secure seating is aided by the cylindrical hole with countersink.

What does the T9225 designation mean for performance?
T9225 indicates a robust universal grade with CVD coating designed for stable chip formation and reliable performance across varying engagement conditions in steel machining.

Can this insert handle interrupted cuts?
The grade’s toughness and the insert geometry are intended to tolerate slightly interrupted cuts; however, final suitability depends on machine rigidity and cutting parameters.
