SPMR 090308 T9225 indexable turning insert — Tungaloy, CVD‑coated carbide, 90°

SPMR090308 T9225 is an ISO‑standard indexable turning insert designed for medium to heavy steel turning and interrupted cuts, offering robust performance in demanding shop applications

• CVD‑coated carbide grade T9225
• Square 90° geometry for versatile turning
• 0.8 mm corner radius for general applications
• One‑sided chipbreaker for controlled chips

Efficient, reliable cutting performance for steel turning

The CVD‑coated carbide composition and the T9225 grade provide a balance of hardness and toughness that supports consistent cutting in medium to heavy machining. This geometry reduces flank wear and extends tool life under variable engagement conditions. The insert's square 90° form allows for stable external and internal turning and offers two usable cutting edges per insert, improving cost efficiency and uptime in production environments.

Better chip control and process stability under interrupted cuts

The one‑sided chipbreaker is tailored to produce stable chip formation with steel grades, helping to avoid entanglement and allowing higher metal removal rates. Combined with the 0.8 mm corner radius and 11° clearance, the insert promotes predictable cutting forces and surface finish while maintaining edge integrity during light interruptions. These characteristics support shorter cycle times and fewer unplanned tool changes.

Practical system integration and ease of selection

Compatibility with holders depends on form, clearance angle, tolerance class, fastening method, size and thickness; the insert is a 3.18 mm thick, hole‑free, square type intended for clamping systems and compatible ISO holders. When selecting the matching holder or boring bar, consider the chipbreaker, grade T9225 and the insert’s geometry to match workpiece material and stability. The modular system—insert plus suitable external holder, clamp set and replacement screw—facilitates rapid changeover and consistent seating for repeatable results.

FAQ

What materials is this insert suited for?
The SPMR090308 T9225 insert is intended primarily for steel machining and performs well in medium to heavy steel turning where robustness and stable chip formation are required.

How does the T9225 grade affect tool life?
The T9225 CVD‑coated grade increases resistance to abrasive wear while retaining toughness, resulting in improved tool life and fewer index changes under variable cutting conditions.

Which holder type is required for this insert?
Because the insert is square and without a hole, a compatible external holder or boring bar with the correct seat, clamp and tolerance class must be used to securely fasten the insert.

Can this insert handle interrupted or unstable cuts?
Yes, the combination of T9225 toughness and the one‑sided chipbreaker makes this insert suitable for light to moderate interrupted cuts common in production turning.

How many cutting edges are available per insert?
The square 90° geometry provides multiple usable cutting edges; flipping and indexing the insert utilises the remaining edges to extend operational life.
