CPMT 090308 T9225 Wendeplatten - Tungaloy

Combining the CVD‑coated cemented carbide grade T9225, an 0.8 mm corner radius and an 11° relief angle delivers robust performance for medium to heavy steel turning and stable chip control under variable engagement; order the insert directly via Metav Werkzeuge or consult the technical team for tailored recommendations.

CPMT 090308 T9225 — Turning ISO insert, CVD‑coated carbide (Tungaloy)

The CPMT090308 T9225 is an ISO‑standard rhombic indexable insert for turning, engineered as a robust universal grade for external and internal machining where interrupted cuts or varying engagement demand extra toughness.

• ISO rhombic insert 09, 80° geometry
• CVD-coated carbide grade T9225
• Single-sided chipbreaker for steel turning
• Cylindrical hole with 40°–60° countersink

Enhanced wear resistance and predictable chip formation

The combination of a CVD‑coated surface and cemented carbide substrate provides a reliable balance between hardness and toughness. The T9225 grade is formulated for productive turning of medium to heavy steel, so the insert sustains edge integrity under fluctuating loads and partially interrupted cuts. Stable chip formation reduces the risk of built‑up edge and contributes to consistent surface finish. As a result, machining cycles become more predictable and tool change frequency can be reduced, improving uptime in production environments.

ISO compliance ensures repeatable clamping and fit

Designed to ISO dimensions, the rhombic 09 geometry and 80° approach angle guarantee compatibility with common external holders and boring bars. The 11° relief angle and the standardised tolerance class ensure secure seating and repeatable positioning, while the cylindrical hole with single‑side countersink (40°–60°) enhances clamping stability in the tooling system. This standardisation supports quick insert replacement and maintains concentricity, which is particularly important when multiple assemblies must deliver identical parts batch after batch.

Productivity gains through longer tool life and process stability

Selecting a robust universal grade like T9225 helps to extend tool life under demanding feed and depth conditions, thereby lowering tool consumption and associated downtime. The single‑sided chipbreaker tailored for steel turning promotes controlled chip evacuation, enabling higher cutting speeds and more consistent cycle times. In practice, this means fewer interruptions for cleaning and a smoother flow through the production line — an economic advantage that becomes significant over many components.

Geometry choices for surface finish and strength

The 0.8 mm corner radius offers a practical compromise between strength and finish: large enough to withstand roughing forces yet small enough to achieve a good surface quality during finishing passes. For heavy cuts or highly interrupted work, pairing the insert with a more robust holder and an appropriate clamping set improves stability further. When choosing the chipbreaker and holder combination, attention to workpiece material and machining strategy will optimise both component accuracy and tool performance, making the system more forgiving under shop‑floor variability.

FAQ

What materials is this insert suited for? The CPMT090308 T9225 indexable insert from Tungaloy is optimised for medium to heavy steel machining and performs well under variable cutting conditions and interrupted cuts.

How does the insert attach to holders and ensure repeatability? Compatibility is determined by form, relief angle, tolerance class and size; the ISO dimensions, cylindrical hole with countersink and standardised thickness enable secure clamping and repeatable seating in ISO‑compliant holders.

Which cutting situations benefit most from the T9225 grade? The T9225 grade is intended for demanding turning operations where toughness and wear resistance are needed simultaneously — for example, roughing heavy cross‑sections, interrupted cuts or unstable engagement scenarios.

How does the chipbreaker affect performance and finish? The single‑sided chipbreaker promotes controlled chip flow during steel turning, which helps to keep the cutting zone clear and supports consistent surface quality while reducing the likelihood of built‑up edge.

What role does the 0.8 mm corner radius play in surface quality? A 0.8 mm corner radius provides increased edge strength for heavier passes while still allowing for acceptable surface finish in follow‑up finishing passes; choice of feed and depth of cut will determine final surface characteristics.
