VNMG 160404 AH6225 – ISO turning insert for Turning (Tungaloy)

A VNMG160404-DM AH6225 indexable insert designed for ISO-standard turning, optimised for machining rostfreier Stahl with a sharp yet stable cutting edge and a 35° cutting angle.

• PVD-coated carbide grade AH6225
• Optimised DM chipbreaker for rostfreier Stahl
• Rhombic 16 × 4.76 mm, 35° cutting angle
• Cylindrical hole for secure clamping

Stable cutting and consistent surface finish for rostfreier Stahl

The PVD-coated carbide grade AH6225 combines a finely honed, sharp cutting edge with substrate toughness to handle the demands of machining rostfreier Stahl. The result is a controlled cutting process with reduced built-up edge and improved surface quality on external and internal turning operations. The DM chipbreaker stabilises chip formation across varied cutting conditions, lowering the risk of vibration and rework while extending effective tool life.

Simple integration and secure clamping for predictable cycles

Designed to ISO standards, the rhombic 16 format with a cylindrical hole and a plate thickness of 4.76 mm ensures compatibility with common outer holders or boring bars. The 0° relief angle and 35° cutting geometry make mounting straightforward and predictable: matching holder form, tolerance class and screw/clamp type provides repeatable positioning and minimal setup time. This clarity in interface reduces changeover delays and supports consistent production throughput.

Durable coating and cost-effective performance in mixed workflows

The PVD coating on this indexable insert increases wear resistance under medium cutting conditions and varying material batches, making it suitable for shops running mixed production. A 0.4 mm corner radius balances edge strength with the capability to produce fine finishes, while the carbide substrate maintains dimensional stability over longer tool life. Selecting the AH6225 grade with the DM chipbreaker supports economical machining by reducing insert consumption and cutting interruptions.
