DNMG150608 AH6225 Turning insert – PVD-coated carbide for stainless steel turning (Tungaloy)

The DNMG150608 AH6225 is an ISO-standard turning insert designed for external and internal turning operations, optimised for machining stainless steels with a sharp yet stable cutting edge.

• PVD-coated carbide for stainless steel machining
• ISO DNMG 150608 rhombic insert, 55° geometry
• Double-sided chipbreaker for versatile use
• Cylindrical hole and 0° clearance for secure clamping

High-performance cutting for stainless steels and changing conditions

The insert delivers consistent cutting performance on stainless steels thanks to the AH6225 PVD-coated carbide grade, which balances edge sharpness and wear resistance. The coating reduces built-up edge and improves surface finish during intermittent cuts and variable feeds, while the substrate maintains edge stability under moderate cutting forces. For manufacturers seeking fewer tool changes and predictable component quality, this combination offers measurable productivity benefits without demanding complex process adjustments.

ISO compatibility and secure clamping for stable turning

Built to the ISO DNMG specification, the insert’s rhombic 55° geometry and cylindrical centre hole make it compatible with a wide range of external holders and boring bars when matched by form, clearance angle and tolerance class. The 0° clearance angle and standardised thickness (6.35 mm) ensure reliable seating and repeatable positioning, simplifying tool setup and reducing downtime during insert changes. Clear reference to geometry and mounting features supports efficient integration into existing tool systems.

Practical advantages in chip control and edge life

The double-sided chipbreaker design provides flexible chip control across common turning tasks, supporting both finishing and medium-accuracy roughing of stainless materials. The 0.8 mm corner radius helps distribute cutting forces and extends edge life while permitting acceptable surface integrity on turned parts. Together, the chip control geometry and the AH6225 grade contribute to lower scrap rates and longer intervals between regrinds or replacements, improving overall machining economy.

Selection guidance and safe handling for workshop use

When selecting an insert, align grade and chipbreaker with workpiece alloy, depth of cut and machine/toolholder rigidity; the AH6225 grade is a universal choice for rostfreie Stähle, especially where a sharp but resilient cutting edge is required. Store inserts in their original packaging, inspect seating surfaces and tightening screws before first use, and observe recommended cutting data from the toolholder or machine manufacturer. For customers less familiar with stainless-steel turning, a short process check under production conditions is advisable to confirm feed and speed settings for optimum tool life.
