DCMT 070202 AH6225 turning insert, 55° rhombic — Tungaloy

The DCMT070202 AH6225 is a PVD-coated carbide indexable insert engineered for external and internal turning, offering a sharp yet robust cutting edge optimised for rostfreier Stahl.

• DCMT070202 geometry, 55° rhombic
• PVD-coated carbide grade AH6225
• 0.2 mm corner radius for fine turning
• Cylindrical hole with one-sided countersink

Consistent cutting performance with economical edge life

The PVD-coated carbide grade AH6225 combines wear resistance with a cutting-edge geometry to deliver reliable results on mixed-production runs. The coating reduces flank wear at moderate cutting depths while maintaining a sharp cutting edge, which supports longer intervals between index changes and stabilises cycle times. For routine external and internal turning, the rhombic 55° form ensures predictable engagement angles and contributes to uniform surface finish without frequent adjustments.

Controlled chip formation for rostfreier Stahl and similar alloys

A single-sided chipbreaker design promotes defined chip separation under varying conditions, improving process security when machining rostfreier Stahl. The controlled chip flow reduces the risk of built-up edge and improves evacuation from confined bores and external contours. Because the grade targets a balance between sharpness and stability, it suits intermittent cuts and variable feed scenarios where consistent chip control prevents downtime and toolholder interference.

Compatibility and clamping considerations for straightforward integration

The insert’s rhombic shape with a cylindrical hole and one-sided countersink (40°–60°) matches common ISO tooling systems; compatibility depends on form, clearance angle, tolerance class, clamping method, size and thickness. With a nominal thickness of 2.38 mm and a relief clearance angle of 7°, the insert integrates into many standard external holders and boring bars when the correct seat and fastener configuration are used. This predictability simplifies tool set-up and reduces adapter or fixture changes in mixed fleets.

Practical advantages for production and maintenance planning

The small 0.2 mm corner radius enables fine finishing passes and dimensional control on narrow profiles, while the universal character of the grade reduces tool inventory complexity across batches. The insert is part of an ISO-based system that uses the indexable plate, suitable holder or boring bar, locating pad/clamp set and replacement screws to form a complete cutting assembly. Specifying this insert supports stable process windows and easier requalification during production runs, contributing to higher throughput and fewer unexpected interruptions.
