DNMG150408 AH6225 Turning Insert (ISO 150408) by Tungaloy — PVD-coated carbide, 55° rhombic

A versatile DNMG150408 AH6225 indexable insert for external and internal turning, optimised for stainless steels and medium-duty machining.

• PVD-coated carbide grade AH6225
• Optimised for stainless-steel turning
• Rhombic 55° geometry, 0° negative rake
• Cylindrical hole, 4.76 mm thickness

Consistent performance for stainless-steel applications

The AH6225 grade is a PVD-coated carbide specifically formulated as a universal solution for machining rostfreie Stähle (stainless steels). The coating enhances wear resistance and helps maintain a sharp, stable cutting edge across fluctuating cutting conditions, which leads to predictable cycle times and reduced tool changes. For process planners, this translates into improved machine utilisation and a gentler load on downstream finishing operations, while operators benefit from a tool grade that resists built-up edge and offers repeatable life in mixed batches.

Geometry and mounting for accurate, repeatable cuts

A rhombic insert with a 55° included angle and 0° negative rake provides a balance between strength and accessibility in tight turning and facing tasks. The 0.8 mm corner radius contributes to surface integrity without excessive cutting forces, while the cylindrical hole and standard ISO dimensions ensure compatibility with a wide range of ISO holders. These geometric choices support stable clamping and minimise deflection; as a result, the insert facilitates consistent tolerances and predictable toolpaths when paired with appropriately rated holders and clamping kits.

Chip control and economical indexability

Equipped with a double-sided chipbreaker, the insert offers two usable cutting edges per side, doubling edge count and lowering per-part tooling costs. The chipformer geometry is designed for medium cutting depths and helps produce manageable chips when turning stainless steels, reducing the risk of entanglement and assisting in uninterrupted production. The indexable format also allows quick edge changes, shortening downtime and supporting lean workflows where rapid recovery after wear is essential.

Practical guidance for selection and use

Intended for external and internal turning, the insert suits medium-duty operations where a stable cutting edge and good surface finish are required. Select feed and speed settings conservatively for work-hardened stainless grades and adjust coolant strategy to control heat at the cutting zone. Compatibility with holders depends on form, relief angle, tolerance class, fixing method, size and thickness; therefore, match the ISO plate to the clamping system specified by the machine-tool supplier. For questions on cutting data or holder pairing, technical advice is available to help tailor parameters to specific materials and stability conditions.

FAQ

What materials is this insert suited for?
The DNMG150408 AH6225 insert is optimised for rostfreie Stähle (stainless steels) and performs well in medium-duty turning operations that demand a stable cutting edge.

How does the AH6225 grade affect tool life and finish?
The PVD-coated AH6225 grade combines wear resistance with a sharp edge, delivering predictable tool life and improved surface finish under varying machining conditions.

Is the insert compatible with standard ISO holders?
Yes, the DNMG150408 follows ISO dimensions; compatibility depends on holder form, relief angle, tolerance class, fixing method, size and thickness, so the correct holder must be selected accordingly.

What benefits does the 0° negative rake and 0.8 mm radius provide?
The 0° negative rake increases edge stability while the 0.8 mm corner radius helps maintain surface quality without excessive cutting forces, suitable for medium-depth turning.

Can chip control be adjusted for different stainless-steel grades?
The double-sided chipbreaker offers reliable chip control for many stainless grades; however, feed, speed and coolant should be adapted to the specific alloy and part rigidity for optimal performance.
