Consistent machining performance for stainless steels

The combination of a PVD-coated carbide substrate and the AH6225 grade provides a balance between edge sharpness and wear resistance, tailored for the demands of machining stainless steels. This composition reduces the risk of built-up edge and maintains cutting-edge integrity under fluctuating feeds and coolant conditions, resulting in longer tool life and fewer insert changes. The rhombic geometry with a 55° included angle produces reliable cutting forces and is suited to both finishing and medium-depth cutting passes, improving process repeatability in batch production.

Designed for straightforward holder compatibility and system integration

The insert follows the ISO standard for rhombic turning inserts, so compatibility with external holders is determined by form, clearance angle, tolerance class, fastening style, size and thickness. The 0° clearance angle and standard dimensions (11 mm size, 4.76 mm thickness) simplify selection of a matching clamping set and screw, and the cylindrical central hole enables secure seating in many common holder designs. Clear labelling of the ISO designation and grade helps streamline inventory management and tool-change procedures on the shop floor.

Reliable chip control and workshop advantages

A double-sided chipbreaker optimised for the AH6225 grade offers consistent chip formation across a range of feeds; this reduces interruptions from tangled or long chips and supports safer, cleaner operation. The 0.8 mm corner radius balances edge strength and surface finish, while the insert’s double-sided nature provides economical use of the cutting edges. Together, these attributes lower downtime, reduce tooling costs over time and support stable cycle times in production environments.

Practical selection guidance and application notes

When specifying an insert for turning, consider the workpiece material, desired surface finish and machine rigidity. The AH6225 grade is a universal choice for stainless steels and suits operations where a dependable edge life under variable conditions is required. In tougher material families or for heavy interrupted cuts a different grade or positive geometry might be preferable; for general-purpose turning at moderate depths this insert provides a strong mix of productivity and process security. If needed, the technical team at Metav Werkzeuge can advise on holder selection, cutting parameters and coolant strategies to match the machining task.

FAQ

What materials is this insert suited for?
The DNMG110408 AH6225 insert is formulated for machining stainless steels; the PVD-coated carbide grade AH6225 gives a sharp, wear-resistant cutting edge suitable for variable conditions.

How does the 0° clearance angle affect cutting?
A 0° clearance angle provides a robust cutting geometry that helps maintain edge stability during medium-depth cuts; the DNMG110408 geometry preserves consistent cutting forces.

How many usable edges does the insert offer?
The insert is double-sided with a reversible design, offering multiple cutting edges for extended tool life; refer to SKU 6903195-Tungaloy for order details.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, tolerance class, fastening method, size and thickness; the ISO rhombic standardisation of the DNMG110408 simplifies selection of a matching external holder or boring bar.
