CCMT09T304 T9225 – ISO turning insert for turning by Tungaloy

The CCMT09T304 T9225 is an ISO-standard rhombic indexable turning insert designed for medium to heavy-duty turning operations, offering a balance of wear resistance and toughness for variable cutting conditions.

• CVD-coated carbide for improved wear resistance
• Universal T9225 grade for medium to heavy steel
• Rhombic CCMT 09 form, 7° clearance angle
• Single-sided chipbreaker and cylindrical hole

Longer tool life through a balanced CVD-coated grade

The CVD-coated carbide substrate delivers a combination of surface hardness and core toughness that reduces flank wear and resists abrasive abrasion during extended runs. The T9225 grade is formulated as a robust universal solution for steel turning where varying engagement or lightly interrupted cuts demand extra toughness. This results in fewer indexings and longer intervals between tool changes, directly improving machine uptime and reducing overall machining costs.

Predictable fit and repeatable accuracy in ISO systems

Designed to ISO dimensions, the insert ensures consistent seating and repeatable geometry when paired with standard holders. The CCMT 09 rhombic shape with a 7° clearance angle and an included angle of 80° provides versatile cutting geometry for both external and internal turning. With a corner radius of 0.4 mm and a plate thickness of 3.97 mm, the insert delivers stable cut engagement and predictable cutting forces, aiding in surface finish and dimensional consistency across batches.

Stable chip control and improved process security

The one-sided chipbreaker is optimised for steel machining and supports effective chip control, particularly under heavier depths of cut. The insert’s cylindrical hole with a single-side countersink (40°–60°) enables secure clamping and accurate positioning on the seat, while the chipformer geometry helps maintain a stable cutting process. The result is fewer interruptions for manual chip clearing and a lower risk of edge fracture in mixed cutting conditions.

Easy selection and integration into workshop workflows

Selection is straightforward: pair the insert with an appropriately rated external holder or boring bar and match form, clearance angle, tolerance class, fastening and thickness to the application. The combination of universal grade, single-sided chipbreaker and standard ISO format simplifies inventory management and supports flexible deployment across turning tasks. For manufacturers aiming to improve throughput without complex retooling, this insert represents a practical step towards greater productivity.

FAQ

What materials is this insert suitable for?
The CCMT09T304 T9225 insert is primarily specified for medium to heavy steel turning and performs well where extra toughness is needed.

How does the T9225 grade behave under interrupted cuts?
Tungaloy’s T9225 grade offers increased toughness compared with finer grades, making the insert more resistant to impact and suitable for lightly interrupted or variable engagement conditions.

Which holder types will fit this insert?
Any ISO-compatible external holder or boring bar designed for CCMT 09 format and matching plate thickness and tolerance class will seat this insert correctly.

What effect does the 0.4 mm corner radius have?
A 0.4 mm corner radius provides a good balance between edge strength and surface finish, helping to absorb cutting forces while maintaining acceptable roughness on turned components.

Is the insert indexable and reversible?
The indexable design allows rotation to a fresh cutting edge when permitted by the chipformer and hole configuration, enabling economical use of each insert face.
