CNMG 160616 AH6225 indexable turning insert (CNMG) by Tungaloy — PVD-coated carbide, 80° included angle

A CNMG160616 AH6225 indexable turning insert for external and internal turning, optimised for mid-range machining of stainless steels and variable operating conditions

• PVD-coated carbide grade AH6225
• ISO rhombic CNMG form, 80° included angle
• Suitable for stainless steel turning
• Double-sided insert with cylindrical hole

Consistent cutting performance for stainless steels

The AH6225 grade is a PVD-coated carbide developed as a universal option for machining stainless steels, delivering a sharp yet stable cutting edge for medium-duty operations. Its chemistry and coating combination prioritise durable edge integrity and improved wear resistance, which supports consistent surface finish and predictable tool life. Where machining conditions vary, the grade helps maintain process stability and reduces unexpected tool changes, contributing to lower overall operating costs.

System compatibility and practical dimensions for easy integration

Designed to the ISO CNMG specification, the rhombic geometry and 80° included angle ensure compatibility with a wide range of external holders and boring bars. Key dimensions — 16 mm size, 6.35 mm thickness, and a 1.6 mm corner radius — define the insert’s engagement and influence achievable radii and surface quality. The insert is double-sided and features a cylindrical hole for positive location and secure clamping; compatibility with holders depends on form, relief angle, tolerance class, fastening and thickness, allowing a predictable fit within standard turning systems.

Operational advantages and recommended uses

Intended for both external and internal turning, the insert’s double-sided design and stable chip formation support efficient tool costs per cutting edge while maintaining productivity. The built-in chipbreaker and the choice of grade make it suitable where mixed materials and variable stability occur on the machine. Typical benefits include reduced downtime for insert changes, improved repeatability in batch production and a balanced compromise between edge sharpness and wear resistance that is particularly useful for medium cutting depths and interrupted cuts.

FAQ

What materials is this insert best suited for?
The CNMG160616 AH6225 insert is formulated for machining stainless steels and performs well in medium-duty turning operations where a balance of edge sharpness and wear resistance is required.

How is the insert secured in the holder?
The insert uses a cylindrical hole and is intended for positive clamping in compatible ISO CNMG holders; secure fastening depends on holder form, tolerance class and clamp design.

Can the same insert be used for external and internal turning?
Yes, the insert’s CNMG geometry and double-sided design allow use in both external turning inserts and appropriate boring-bar setups for internal turning.

How does the AH6225 grade affect tool life?
The AH6225 PVD-coated carbide promotes stable chip formation and a robust cutting edge, which together improve predictability of tool life under varying machining conditions.
