DPMT 070208 AH6225 indexable turning insert for turning, Tungaloy — rhombic, 11° clearance

DPMT070208 AH6225 is a compact ISO-format indexable insert designed for external and internal turning of stainless steels, offering a sharp yet robust cutting edge and predictable compatibility with ISO holders.

• DPMT070208 geometry, rhombic 07 size
• PVD-coated AH6225 for stainless steel
• 11° clearance angle for stable cutting
• Cylindrical hole with 40°–60° countersink

Consistent edge life and material versatility for stainless-steel turning

The PVD-coated AH6225 grade is engineered as a universal carbide for stainless steel machining, combining a fine, wear-resistant coating with a substrate that supports a sharp, stable cutting edge under variable conditions. This results in consistent tool life and fewer unexpected interruptions in batch production. The insert’s composition makes it suitable for medium cutting applications where a balance of edge retention and toughness reduces regrind frequency and improves overall process economy.

Predictable fit and secure clamping for reliable tool changes

Designed to the ISO turning insert system, the geometry, clearance angle and dimensional tolerances of this insert determine holder compatibility. The rhombic 07 format and 11° clearance mean that common external holders and boring bars accept the piece without modification, minimising set-up time. The insert’s cylindrical hole with a single-sided countersink (40°–60°) ensures repeatable clamping force and positional stability, which reduces chatter and improves surface consistency after each index or replacement.

Better chip control and effective cutting performance

A single-sided chipbreaker matched to the AH6225 grade assists in forming controllable chips during interrupted or steady cuts, helping to avoid long, stringy swarf that can damage the workpiece or tool. The 0.8 mm nose radius and the insert’s approach geometry contribute to a good surface finish while maintaining adequate strength at the cutting edge. For machinists new to the grade, the combination of chipbreaker and PVD coating translates into fewer tool changes and more predictable cycle times on stainless-steel components.

Practical dimensions and shop-floor integration for immediate use

With a thickness of 2.38 mm and the ISO 07 size, the insert integrates into standard inventories and is easy to store alongside compatible underplates and clamping sets. The modest profile reduces interference in tight bores while the rhombic outline gives flexibility for multiple cutting positions per insert. When selecting the chipbreaker and holder, match the insert’s form, free angle, size and thickness to the tooling system to make the most of its productive capabilities; this approach supports high machine uptime and repeatable part quality.
