SPMT 120408 T9215 — ISO turning insert, CVD-coated carbide, 90° square (Tungaloy)

SPMT 120408 T9215 is an ISO-standard square turning insert engineered for external and internal turning of medium steels, offering CVD-coated carbide for enhanced wear resistance and consistent performance.

• CVD-coated carbide grade T9215
• 90° square geometry for stable cutting
• 0.8 mm corner radius for profile accuracy
• Cylindrical hole with 40°–60° countersink

Delivering measurable productivity through material and geometry

The combination of a CVD-coated surface and a T9215 carbide substrate delivers elevated wear resistance while retaining fracture toughness suitable for continuous to slightly interrupted cuts. The square 90° geometry increases tool support in the holder, which helps maintain dimensional stability and repeatability when facing or turning shoulders. A 0.8 mm corner radius balances edge strength and profile accuracy, reducing the need for secondary passes and therefore improving overall cycle times. These technical characteristics translate directly into higher throughput and fewer insert changes during standard steel turning operations.

Clear compatibility and secure clamping save set-up time

Designed as an ISO-standard insert, the component is compatible where shape, free clearance, tolerance class, clamping and thickness match the toolholder specification. The plate measures 12 mm across with a thickness of 4.76 mm, and a 11° free clearance angle to fit common holders; the central cylindrical hole with a 40°–60° countersink supports reliable seating and repeatable clamping. For engineers and buyers this means straightforward integration into existing tool systems: select the corresponding holder by form and tolerance, fit the insert to the clamping set and secure with the recommended screws to restore consistent cutting geometry quickly.

Single-sided chip control and application guidance for consistent results

The single-sided chipbreaker is optimised for medium-steel turning and supports effective chip control in both external and internal operations. When the single-sided chipbreaker is paired with the T9215 grade, the result is a balance of controlled chip formation and edge life that suits continuous production runs. For best results, match the chipbreaker and grade to the workpiece material and stabilise the set-up to avoid excessive interruptions; a rigid toolpost and correct depth of cut extend insert life and enhance surface finish. The SPMT 120408 T9215 insert is particularly suited to workshop environments where predictable performance and low variability are priorities.

FAQ

What materials is this insert intended for?
The T9215 grade is primarily intended for medium steel machining; the SPMT 120408 T9215 insert combines wear resistance and toughness for productive turning of such materials.

How does the insert locate in the holder?
Location is by ISO-compatible form and the central cylindrical hole with a 40°–60° countersink ensures secure seating; the listed 12 mm size and 4.76 mm thickness must match the holder specification.

Which chipbreaker should be chosen for interrupted cuts?
The single-sided chipbreaker on this insert is tuned for continuous to slightly interrupted cuts; for heavily interrupted conditions a different chipforming geometry or a more robust grade should be selected.

Is this insert suitable for internal turning as well as external turning?
Yes, the geometry and chip control make it suitable for both external and internal turning, provided the holder and stability are appropriate for the application.

What determines compatibility with an existing toolholder?
Compatibility is determined by insert form, free clearance, tolerance class, clamping design, size and thickness — ensure the toolholder matches these parameters for repeatable clamping.
