SPMT 120408 T9225 – ISO turning insert for Drehen (Tungaloy)

The SPMT120408 T9225 is an ISO‑standard indexable turning insert designed for medium to heavy steel turning, offering a rugged universal grade for interrupted cuts and variable engagement conditions

• SPMT120408 ISO insert, square form
• CVD‑coated cemented carbide T9225
• For medium to heavy steel turning
• 11° relief angle, 0.8 mm corner radius

Reliable performance when cutting conditions vary

The insert’s combination of a CVD coating and cemented carbide substrate provides a dependable balance between wear resistance and toughness. This makes it particularly suitable for operations where the engagement fluctuates or where light interruptions occur in the cut. The T9225 grade is formulated as a robust universal sort for medium to heavy steel machining; the coating reduces flank wear while the substrate maintains edge stability, resulting in more consistent tool life and fewer unexpected breaks. In practice, this translates into stable cycle times and reduced tool change frequency, supporting a smoother production flow.

Fast locating and secure clamping for repeatable accuracy

The square plate geometry combined with a central hole and single‑side countersink (40°–60°) enables straightforward positioning on compatible holders and ensures repeatable seating. Key dimensions such as the 12 mm plate size, 4.76 mm thickness and the 0.8 mm corner radius are standardised to ISO norms, simplifying tool selection and holder compatibility. The 11° relief angle promotes reliable cutting clearance and reduces rubbing, while the central bore and countersink secure the insert against lateral forces. These design choices lower setup time and contribute to reproducible part quality in batch production.

Clear application focus and easy specification for purchasing

The insert is part of an ISO series intended for external and internal turning; compatibility with a specific holder depends on form, relief angle, tolerance class, fastening method, size and thickness. The single‑sided chipbreaker supports predictable chip formation for common steel turning tasks, and the square form offers four usable cutting edges per index, improving cost efficiency. For procurement, the manufacturer article number and the manufacturer SKU support fast cross‑referencing and ordering, while the ISO designation facilitates comparison across suppliers.

FAQ

What materials is this insert best suited for?
The SPMT120408 T9225 insert is formulated for medium to heavy steel machining and performs well where slightly interrupted cuts and variable engagement demand extra toughness.

How many cutting edges are available per insert?
The square geometry provides four indexable cutting edges; indexing the SPMT120408 restores a fresh edge quickly to reduce downtime.

What does the T9225 designation indicate?
T9225 denotes a robust universal grade with a CVD coating on a cemented carbide substrate, optimised for process reliability in steel turning.

Which holders are compatible with this insert?
Compatibility depends on holder form, relief angle, tolerance class, fastening style, size and thickness; Metav Werkzeuge can recommend matching external holders or boring bars.

Is the insert suitable for interrupted cuts?
Yes, the grade and substrate combination of the SPMT120408 makes it well suited to interrupted or variable engagement conditions, improving edge stability under shock loads.
