VNMG160408-PM AH6225 — ISO turning insert for stainless-steel applications by Tungaloy, PM chipbreaker

VNMG160408-PM AH6225 is an ISO rhombic turning insert optimised for external and internal turning operations in stainless steels, offering a sharp yet stable cutting edge for medium machining conditions.

• ISO VNMG160408 rhombic insert
• PVD-coated carbide grade AH6225
• PM chipbreaker for stable cutting
• 0.8 mm corner radius, 35° lead angle

Higher cutting stability and consistent surface finish

The combination of PVD-coated carbide and the AH6225 grade delivers an excellent balance between edge sharpness and wear resistance, making this insert suitable for medium-duty turning in stainless steels. The PM chipbreaker controls chip form under changing conditions, reducing chatter and minimising workpiece rework. By selecting a chipbreaker matched to the machining scenario, process reliability is increased and cycle times can be shortened without compromising surface integrity.

Easy integration into ISO turning tool systems

Manufactured to ISO dimensions, the ISO VNMG160408 format enables straightforward replacement in compatible holders and boring bars; compatibility is ensured by matching form, clearance angle, tolerance class, clamping method, size and thickness. The insert’s rhombic profile with a cylindrical hole allows secure clamping and simple orientation, while the 35° lead angle supports versatile turning strategies for both external and internal operations. This makes tool management simpler and reduces setup time at the machine.

Predictable tool life and practical handling

With a 0.8 mm corner radius, the cutting edge balances strength and detail for medium feeds, improving edge durability during intermittent cuts. The PVD coating enhances resistance to built-up edge formation in stainless steels and supports thermal stability under elevated cutting temperatures. These characteristics contribute to repeatable tool life and predictable regrinding intervals, helping to plan production runs with greater confidence and lower scrap rates.
