DCMT11T308 AH6225 indexable turning insert – rhombic 55° geometry | Tungaloy

The DCMT11T308 AH6225 is an ISO-standard indexable insert engineered for external and internal turning of stainless steels, offering a sharp yet robust cutting edge for medium machining conditions

• PVD-coated carbide for stainless steel
• 0.8 mm corner radius for reliable edge
• Rhombic 55° insert for versatile turning
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance for stainless steels

The AH6225 grade combines a PVD coating with a wear-resistant carbide substrate to deliver a balance of edge sharpness and stability. This results in a predictable cutting behaviour in the often-demanding metallurgy of stainless steel, reducing chatter and improving surface finish. By selecting a universal grade designed for changing conditions, operators gain the rational benefit of fewer insert changes and more consistent cycle times, supporting efficient shop-floor planning and cost control.

Geometry and clamping that support process reliability

A rhombic 55° geometry with a 0.8 mm corner radius provides flexibility for a range of turning tasks, permitting modest step-over depths while maintaining strength at the insert tip. The insert is ISO-conforming, with a 7° clearance angle and a plate thickness of 3.97 mm, which together ensure compatibility with standard holders when form, fixation and tolerance class match. The cylindrical hole with a single-sided countersink (40°–60°) secures repeatable clamping and simple indexation, reducing set-up time and contributing to reproducible component quality.

Practical advantages and recommended applications

Designed for both external and internal turning, this single-sided chipbreaker insert suits medium machining of stainless steels where a stable cutting edge is required. The combination of a universal chipbreaker and the AH6225 grade delivers a consistent surface finish and predictable tool life, helping to avoid unscheduled downtime. For best results, pair the insert with a correctly matched external holder or boring bar and select the chipbreaker and cutting parameters to suit the component material and machine rigidity.

FAQ

What materials is this insert suitable for?
The DCMT11T308 AH6225 insert is formulated for machining stainless steel, with the AH6225 PVD-coated carbide grade offering good performance across varying stainless alloys.

Which holder types are compatible with this insert?
Compatibility depends on holder form, clearance, tolerance class, fixation, size and thickness; the ISO-standard design of the DCMT11T308 ensures it fits standard external holders and boring bars that accept rhombic 55° inserts.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm radius increases edge strength compared with a finer point, improving resistance to chipping and helping to achieve consistent surface quality in medium cutting conditions.

Is the insert single- or double-sided, and what does that mean for inventory?
This is a single-sided insert with a single-sided chipbreaker; while it offers fewer cutting edges per insert than double-sided types, the universal AH6225 grade can reduce the total number of different inserts required for stainless steel applications.
