DPMT070204 AH6225 Tungaloy indexable insert — for turning, PVD-coated carbide, 55° rhombic

The DPMT070204 AH6225 indexable insert is a 55° rhombic turning plate, designed for medium machining of stainless steels with a single-sided chipbreaker and cylindrical hole for secure clamping.

• PVD-coated carbide grade AH6225
• Optimised for stainless steel turning
• 55° rhombic form DPMT070204
• 0.4 mm corner radius, stable cutting edge
• Cylindrical hole with single-sided countersink

Reliable cutting performance for stainless steels and mixed conditions

The combination of a PVD-coated surface and a modern carbide substrate provides a balanced cutting edge that resists wear while remaining sharp enough for controlled metal removal. The AH6225 grade is formulated for stainless steels, offering good edge stability under changing conditions and medium cutting parameters. This results in consistent dimensional accuracy and surface finish when performing external or internal turning operations. The 0.4 mm corner radius supports reduced cutting forces and improved edge life compared with finer radii, making the insert suitable for a range of component geometries without frequent tool changes.

Straightforward compatibility and secure clamping for ISO turning systems

The rhombic 55° geometry conforms to ISO turning insert standards and fits into matching external holders or boring bars where form, relief angle and tolerance class align. The insert’s cylindrical hole with single-sided countersink (40°–60°) ensures reliable seating and repeatable positioning in the clamping pocket. For workshop planning, note the plate thickness of 2.38 mm and size designation 07 when selecting a compatible holder or screw set. Correct selection of holder and mounting hardware helps to maintain rigour in process set-up and reduces vibration, which improves tool life and part quality.

Economical machining through robust coating and controlled chip formation

A single-sided chipbreaker matched to the grade promotes controlled chip flow when turning stainless steels, reducing the risk of stringing and improving surface integrity. The PVD coating enhances thermal resistance and reduces built-up edge tendencies common with stainless materials. Together with the stable cutting edge, this leads to longer intervals between indexings and lower tool consumption overall. For production environments seeking predictable cycle times and repeatable results, the insert’s balanced specification supports process stability and efficient use of machine time.
