DCMT 11T312 AH6225 Tungaloy turning insert — PVD-coated carbide, 1.2 mm radius

The DCMT11T312 AH6225 is an ISO‑standard indexable insert for external and internal turning, optimised for machining rostfreie Stähle with a sharp, stable cutting edge and single‑sided chipbreaker.

• PVD-coated carbide AH6225 for stainless steels
• Sharp, stable cutting edge for medium-duty turning
• Rhombic format DCMT 11T312 with 1.2 mm radius
• Cylindrical hole with 40°–60° countersink for secure clamping

Consistent machining performance for rostfreie Stähle

The combination of a PVD-coated surface and a wear‑resistant carbide substrate provides predictable tool life and consistent cutting behaviour when machining stainless steels. The chosen grade delivers a sharp cutting edge that resists chipping under varying conditions, which translates into fewer interruptions and more stable cycle times. For production environments aiming for repeatable part quality, the coating reduces built‑up edge and helps maintain dimensional accuracy over longer tool life.

Plug‑and‑play compatibility reduces setup time

Designed as an ISO-standard turning insert, the geometry and fixing details ensure compatibility with common external holders and boring bars. The rhombic plate form and the cylindrical hole with single-sided countersink (40°–60°) enable secure clamping and repeatable indexation. With a 7° clearance and a plate thickness of 3.97 mm, the insert fits standard toolholders and simplifies inventory management by matching established holder geometries and tolerance classes.

Controlled chip formation and reliable surface finish

The single-sided chipbreaker is tuned to medium turning operations and assists in breaking and evacuating chips reliably, reducing cycle variability and improving surface quality. In less technical terms, the chipbreaker shapes the chip so it clears the cutting zone without entangling, which is particularly useful when turning longer parts or interrupted cuts. Combined with the grade’s edge stability, this results in good surface finishes and reduced secondary operations.

Application guidance and suitability

The insert is intended for turning applications where a balance between edge sharpness and stability is needed. Typical setups include external and internal turning of rostfreie Stähle using a matching external holder or boring bar, an underlay/clamping set and replacement screws as required. Selection of the chipbreaker and grade should be matched to the workpiece material, machining parameters and machine stability to achieve the best cycle economy.

FAQ

What materials is this insert intended for?
The DCMT11T312 AH6225 insert is designed primarily for machining rostfreie Stähle, offering a balance of sharpness and edge stability for medium turning tasks.

How does the chipbreaker affect performance?
The single-sided chipbreaker on this Tungaloy turning insert assists in chip control and evacuation, improving surface finish and reducing the risk of chip interference during turning.

Which toolholders are compatible with this insert?
Compatibility depends on holder geometry, free angle, tolerance class, fixation and plate thickness; the ISO‑standard form of the insert ensures fitment with commonly used external holders and boring bars.

What are the key dimensional values to check before ordering?
Verify the corner radius (1.2 mm), plate size (11), plate thickness (3.97 mm) and the hole/countersink style to ensure correct clamping and indexing.

Is the grade coated and what benefit does the coating provide?
The AH6225 grade is PVD-coated, which helps reduce built‑up edge and extends consistent cutting performance when turning rostfreie Stähle.
