CPMT 090308 T9225 indexable insert — ISO-standard turning insert by Tungaloy

CPMT090308 T9225 is an ISO-standard rhombic indexable insert designed for medium to heavy steel turning in external and internal operations

• CVD-coated carbide grade T9225
• Universal use for medium to heavy steel turning
• ISO rhombic insert with 11° relief angle

Consistent cutting performance under variable conditions

The CVD-coated carbide grade T9225 is formulated as a robust universal grade for the mid-to-heavy duty turning of steel, offering increased toughness where interrupted cuts or changing engagement conditions occur. As an ISO-standard indexable insert, this grade combines wear resistance with fracture resistance, so chip formation remains stable and tool life is extended. The combination of the single-sided chipbreaker and the geometry chosen reduces cutting forces and supports consistent surface finish without complex process tuning.

Geometry and clamping for reliable toolholder compatibility

The rhombic plate form with a cylindrical hole and one-sided countersink (40°–60°) ensures straightforward clamping in a wide range of ISO holders. Compatibility is determined by form, relief angle, tolerance class, attachment, size and thickness; the specified 11° relief angle and 3.18 mm thickness make this insert suitable for stable, repeatable positioning in standard external and internal turning holders. The corner radius 0.8 mm provides a balance between edge strength and achievable contour detail, reducing the risk of corner chipping in tougher cuts.

Operational efficiency and typical applications

As a purpose-made turning grade, the insert is intended for typical lathe operations where economy and process reliability matter. The T9225 grade performs well in fluctuating cutting conditions common in batch and job-shop production, enabling longer intervals between indexings and fewer tool changes. Its single-sided chip control assists in predictable swarf evacuation, lowering machine downtime and simplifying process planning for steel turning tasks — especially where a combination of surface quality and robustness is required.

FAQ

What materials is this insert suited for? The CPMT090308 T9225 indexable insert is specified for medium to heavy steel turning; the CVD-coated carbide grade T9225 provides toughness for interrupted cuts and variable engagement in steel machining.

How is holder compatibility determined? Compatibility depends on the insert form, relief angle, tolerance class, attachment method, size and thickness. The rhombic form, 11° relief angle and 3.18 mm thickness align with common ISO toolholder standards for turning.

Does the insert support internal turning as well as external turning? Yes — the ISO rhombic geometry and the clamping hole with countersink enable use in holders intended for both external and internal turning operations.

What purpose does the single-sided chipbreaker serve? The single-sided chipbreaker promotes consistent chip formation and evacuation in typical turning conditions, contributing to stable cutting performance and reduced risk of swarf-related interruptions.

Are special clamping screws or adapters required? Standard clamping systems for ISO indexable turning inserts are compatible; the cylindrical hole and one-sided countersink (40°–60°) suit conventional insert fastening arrangements.
