DPMT 11T308 T9215 — Indexable turning insert for medium steel by Tungaloy

DPMT11T308 T9215 Tungaloy indexable insert is a rhombic ISO insert designed for external and internal turning in medium steel applications

• CVD-coated carbide grade T9215
• Rhombic 55° geometry for versatile turning
• Single-sided chipbreaker for reliable chip control
• 0.8 mm corner radius for robust edge life

Reliable productivity for medium steel turning

The CVD-coated carbide of grade T9215 combines high wear resistance with good fracture toughness, making it an efficient choice for continuous to slightly interrupted turning of medium steel. This indexable insert delivers consistent performance across extended runs, reducing tool change frequency and supporting higher throughput. The coating enhances edge life under elevated temperatures, which translates into predictable tool life and lower overall machining costs.

Geometry and clamping compatibility that minimise setup issues

With an ISO designation and a rhombic form, the insert is compatible with standard ISO clamping systems when the holder matches by form, relief angle and tolerance class. The insert features a 55° cutting angle, an 11° relief angle and a 3.97 mm thickness, parameters that influence cutter engagement and rigidity. Correct pairing with an external holder or boring bar plus the appropriate shim and clamping kit ensures secure seating and repeatable results on centre-turning operations.

Stable cutting edge and controlled chip formation

The single-sided chipbreaker and a 0.8 mm radius create a robust cutting edge that handles moderate depth of cut while promoting predictable chip flow. The combination of chipbreaker geometry and the T9215 grade improves surface finish under stable conditions and reduces the risk of edge chipping, which is particularly valuable when machining long components or when high part-to-part consistency is required.

System approach and recommended application practice

This insert is supplied in the ISO series intended for turning and is best used with a matching holder, clamping set and replacement screws as part of a system. Typical applications include external and internal turning where continuous or slightly interrupted cuts are expected. Select the chipbreaker and grade according to material, machining type and machine stability to extract the full productivity potential of the cutting system.

FAQ

What materials is this insert best suited for?
The DPMT11T308 T9215 Tungaloy insert is optimised for medium steel machining and offers a balance of wear resistance and edge toughness for continuous to slightly interrupted cuts.

Which holder features must be matched for proper compatibility?
Compatibility depends on holder form, relief angle, tolerance class, attachment method, size and thickness; ensure the external holder or boring bar matches the ISO geometry and clamping style.

What does the T9215 grade indicate?
T9215 denotes a CVD-coated carbide grade designed for productivity in medium steel, combining high wear resistance with good fracture safety for stable machining.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm radius provides a robust cutting edge that improves tool life under moderate feeds and contributes to consistent surface finish and reduced edge chipping.

Is this insert suitable for interrupted cuts?
Yes—T9215 is suitable for continuous to slightly interrupted cuts; heavier interruptions may require a different chipbreaker or a tougher grade.
