CPMT09T302 T9215 — Indexable turning insert for turning (Tungaloy)

The CPMT09T302 T9215 is an ISO-format indexable insert engineered for external and internal turning, optimised for medium-steel machining.

• CVD-coated carbide for high wear resistance
• Optimised for medium-steel turning
• Rhombic 09 form with 11° relief angle
• Single-sided chipbreaker for interrupted cuts

Engineered for sustained productivity with consistent wear control

The T9215 grade combines a CVD-coated carbide substrate with a formulation designed to balance wear resistance and fracture resistance, making it well suited to continuous and slightly interrupted cutting. The result is fewer tool changes and steadier cycle times in production environments. The insert’s grade supports productive machining of medium steels while maintaining edge stability, which in practice reduces unplanned downtime and contributes directly to improved shop-floor throughput.

Clear compatibility and secure mounting for fast set-up

Being an ISO-format indexable insert, the part adheres to standard indexing and clamping conventions: the rhombic 09 outline, the 11° relief angle and the specified thickness ensure predictable fit in compatible external holders and boring bars. The insert features a cylindrical hole with a one-sided countersink (40°–60°) for secure clamping and easy orientation. Such standardised geometry simplifies tool inventory and shortens set-up times, while the defined tolerances help maintain repeated positioning accuracy across jobs.

Fine surface finish and adaptable chip control with minimal adjustment

A 0.2 mm corner radius provides a balance between cutting robustness and surface quality, enabling finer finishes on external and internal profiles without excessive feed reductions. The single-sided chipbreaker is matched to permit reliable chip control on the intended materials; selecting the correct chipbreaker and grade for the workpiece, machining method and machine rigidity will yield the best outcome. The insert’s 3.97 mm thickness contributes to edge support, reducing vibration and improving dimensional stability during turning.

FAQ

What materials is this insert intended for?
The CPMT09T302 T9215 is formulated for machining medium steel, offering a balance of wear resistance and toughness suitable for productive steel turning operations.

Can the insert handle interrupted cuts?
Yes, the T9215 grade is suitable for continuous to slightly interrupted cuts; the single-sided chipbreaker further supports chip control during light interruptions.

Which holders are compatible with this insert?
Compatibility depends on holder form, relief angle (11°), tolerance class, clamping method, insert size (09) and thickness (3.97 mm); use holders designed for ISO-format rhombic inserts of the CPMT designation.

How does the 0.2 mm corner radius affect surface finish?
A 0.2 mm corner radius improves edge strength while permitting finer surface finishes compared with larger radii, reducing the need for secondary finishing in many turning tasks.

Is the insert suitable for internal as well as external turning?
Yes, the insert’s form and thickness support both external and internal turning applications when paired with an appropriate boring bar or holder.
