CNMG090404 AH6225 Tungaloy turning insert — PVD-coated carbide, 0.4 mm nose radius, 80° rhombic

A CNMG090404 AH6225 Tungaloy turning insert designed for external and internal turning of stainless steels, offering a balance of sharpness and edge stability for medium machining.

• PVD-coated carbide AH6225
• Designed for stainless steels
• 0.4 mm nose radius for fine finishes
• 80° rhombic insert with central hole
• Double-sided chipbreaker, reusable

Higher productivity through a balanced cutting concept

The PVD-coated AH6225 grade is developed for consistent performance on stainless steels, combining a sharp cutting edge with sufficient edge strength for varying conditions. The PVD-coated surface reduces adhesion and improves wear resistance, which in practical terms means longer in-process life and fewer tool changes. For shops running mixed batches or changing setups frequently, this insert offers measurable gains in uptime and process stability without sacrificing surface quality.

Secure system fit and straightforward handling for production environments

As an ISO-standard insert, compatibility with holders depends on form, relief angle and tolerance class; the rhombic geometry with an 80° included angle and a central hole supports stable clamping and exact seating in standard toolholders. The plate has a thickness of 4.76 mm and uses a 0° relief angle, which affects how the insert engages the workpiece and how cuts are supported. Clear specification of these parameters simplifies tool selection and reduces setup time on lathes and bar-feed machines.

Better chip control and extended edge life for cost-effective turning

The double-sided chipbreaker provides controlled chip formation in a range of cutting conditions, improving coolant access and reducing rework caused by poor chip evacuation. The combination of carbide substrate and PVD finish helps maintain a stable cutting edge during medium-duty turning, resulting in a consistent surface finish and predictable tool-change intervals. This reliability supports planning for tool inventories and contributes to a lower cost per component over production runs.

Practical applications and selection guidance for machinists

Intended for turning operations, this insert suits both external and internal machining where stainless steels are predominant. The 0.4 mm nose radius favours fine finishing and dimensional control on turned parts; for roughing or heavier cuts, a different radius or an alternative chipbreaker should be chosen. When matching to a holder, verify form, thickness and fastening method to ensure correct seating.
