DCMT11T308 11T308 AH6225 Turning insert — PVD-coated carbide, 55° rhombic, Tungaloy

The DCMT11T308 is an ISO rhombic turning insert designed for external and internal turning, delivering a stable cutting edge and versatile performance in varying workshop conditions.

• PVD-coated carbide AH6225
• Optimised for rostfreier Stahl machining
• Rhombic DCMT form with 55° cutting angle
• 0.8 mm corner radius for robust edge
• Single-sided chipbreaker; cylindrical hole

Efficient cutting performance and predictable tool life

The PVD-coated carbide grade AH6225 offers a balance between a sharp cutting edge and edge stability, making it particularly suitable for medium cutting operations under changing conditions. The PVD coating reduces flank wear and improves surface integrity, which translates into fewer insert changes and lower process costs over time. For workshops that value throughput and consistent quality, this insert reduces unexpected downtime while maintaining reliable part finish. The proven geometry supports sustained metal removal rates without sacrificing edge life, so production runs remain predictable.

Seamless integration into ISO holder systems

Compatibility with ISO holder systems is governed by form, relief angle, tolerance class, mounting, size and thickness; the rhombic DCMT form and the specified relief angle ensure correct seating and repeatable positioning. Using the correct clamping kit and replacement screws completes the system: insert, suitable external holder or boring bar, shim/clamping set and spare screws. This clarity in system setup simplifies tool management and stocking, reduces set-up time between jobs and ensures that a change of insert restores original cutting conditions quickly and reliably.

Geometry engineered for reliable machining results

The 55° lead angle and 0.8 mm corner radius create a cutting geometry that combines strength with a good surface finish, while the single-sided chipbreaker directs chips consistently for safer evacuation. The plate’s cylindrical hole with a one-sided countersink (40°–60°) provides secure clamping and accurate seating under cutting forces. Together, these features deliver repeatable part quality and lower burr formation, especially when machining rostfreier Stahl. The robust carbide core resists chipping at interruptions, and the rhombic shape offers flexibility for both external turning and internal operations where access and clearance are factors.

FAQ

What applications is this insert suitable for?
The DCMT11T308 AH6225 Tungaloy turning insert is intended for external and internal turning; the AH6225 grade is a universal choice for rostfreier Stahl and medium cutting conditions.

How does one ensure correct holder compatibility?
Compatibility is determined by form, relief angle, tolerance class, mounting, size and thickness; selecting an ISO-compatible holder and correct clamping set ensures the DCMT11T308 seats and clamps reliably.

Can this insert deliver a good surface finish?
Yes, the combination of the PVD-coated carbide AH6225, the 55° geometry and the 0.8 mm corner radius produces a stable cutting edge that supports consistent surface quality in finishing and semi-finishing passes.

Is the insert suitable for interrupted cuts or unstable conditions?
The robust carbide substrate and the optimised edge geometry provide resistance to chipping, making the insert suitable for operations with occasional interruptions or variable machining conditions.

What does the hole and countersink style affect in practice?
The cylindrical hole with a single-sided countersink (40°–60°) secures accurate seating and clamping, reducing the risk of movement under load and improving repeatability for production runs.
