DPMT 070202 AH6225 indexable turning insert — Tungaloy (PVD-coated carbide, 55°)

DPMT070202 AH6225 is an ISO-compliant indexable insert designed for reliable external and internal turning, optimised for stainless-steel machining.

• DPMT 070202 geometry, rhombic 55° angle
• PVD-coated carbide AH6225 for stainless steel
• 0.2 mm corner radius for fine finishes
• Cylindrical hole with single-sided countersink

Consistent cutting performance for stainless steels

The AH6225 grade is a PVD-coated carbide designed as a universal solution for rostfreie Stähle under varying machining conditions. Its combination of a sharp yet stable cutting edge and wear-resistant coating supports sustained cutting performance during medium-depth cuts. The insert’s material and coating reduce built-up edge and improve tool life, which leads to fewer tool changes and increased uptime. For customers seeking predictability in mixed-batch production, this grade provides a balanced compromise between durability and cutting-edge sharpness.

Geometry and clamping that support precision turning

The rhombic 55° geometry with a 0.2 mm corner radius yields a controlled cutting force and good surface quality on external and internal profiles. The insert is supplied with a cylindrical hole and a single-sided countersink (40°–60°) to ensure secure seating and repeatable clamping in ISO holders; compatibility depends on holder form, clearance angle, tolerance class, fastening and insert thickness. The plate thickness of 2.38 mm and the ISO designation 070202 simplify selection for standard turning toolholders, while the single-sided chipbreaker aids chip control in stable setups.

Practical advantages for process reliability and surface finish

Using an insert with these characteristics improves process stability and helps achieve consistent part quality. The PVD coating enhances edge protection at elevated temperatures, while the single-sided chipbreaker directs chips away from the cutting zone, reducing recutting and potential surface damage. For short-run production or setups with variable stability, selecting the appropriate chipbreaker and adjusting feed rates in line with the insert’s geometry will quickly deliver measurable improvements in cycle time and finished-part appearance. For less experienced teams, the ISO coding and clear geometry data make integration into existing tooling systems straightforward.

FAQ

What materials is this insert suitable for?
The DPMT070202 AH6225 indexable insert (Tungaloy, SKU 6951265) is formulated primarily for stainless steels and performs well where a stable, sharp cutting edge is required under varying conditions.

Which turning operations are appropriate for this insert?
The insert is intended for both external and internal turning; the rhombic 55° geometry and single-sided chipbreaker suit medium-depth cuts and profile work.

How is the insert clamped and what should be checked for compatibility?
Clamping uses the cylindrical hole with a one-sided countersink; compatibility is determined by holder form, clearance angle, tolerance class, fastening, size and thickness—ensure the holder matches the ISO 070202 specification.

What surface finish can be expected when using this insert?
With a 0.2 mm corner radius and the AH6225 grade, the insert delivers a fine surface finish when used with appropriate feeds and stable setup, aided by the PVD coating’s thermal resistance.

Is the AH6225 grade suitable for interrupted cuts or unstable setups?
AH6225 offers a balanced edge stability, but for highly interrupted cuts or unstable setups it is recommended to evaluate chipbreaker selection and cutting parameters to ensure tool life and part quality.
