CNMG160612 AH6225 ISO rhombic turning insert — PVD‑coated carbide, 80° angle (Tungaloy)

A CNMG160612 AH6225 rhombic ISO turning insert designed for external and internal turning, optimised for machining stainless steels under varying conditions

• ISO rhombic insert, 80° included angle
• PVD-coated carbide for stainless steels
• 1.2 mm corner radius for stable edges
• Double-sided chipbreaker, cylindrical hole

Stable edges and wear resistance for stainless steel work

The combination of a PVD‑coating with a robust carbide substrate gives the insert a sharp yet durable cutting edge that performs reliably in medium turning tasks on stainless steels. The AH6225 grade is formulated to maintain a stable cutting edge under fluctuating cutting conditions, reducing flank wear and edge chipping. This results in consistent component quality and longer intervals between indexings, supporting uninterrupted production runs and predictable tool-change schedules.

Interchangeability and secure clamping for rapid setup

Built to ISO form specifications, the rhombic geometry with an 80° included angle ensures compatibility across standard external holders and boring bars. The cylindrical hole facilitates secure clamping and correct seating in many clamping systems, minimising runout and vibration. Clear ISO conformity shortens setup times, simplifies tool inventory and enables fast replacement with matched tolerances, which collectively contribute to higher machine utilisation and reduced setup-related downtime.

Controlled chips and improved surface quality

The double-sided chipbreaker is engineered for reliable chip control during both external and internal turning. Effective chip management reduces the risk of entanglement in the cutting zone, helps maintain coolant contact and supports a consistent surface finish. In applications where process stability varies, this chip control capability assists in achieving repeatable results and reduces manual interventions, enhancing overall process reliability.

Versatility, application scope and economic benefits

With a 1.2 mm corner radius and a plate thickness of 6.35 mm, the insert is suited to medium turning operations where a compromise between finish and edge strength is required. The grade’s balanced properties make it a pragmatic choice for shops processing a range of stainless steel grades under changing conditions. The resulting combination of tool life and machining stability contributes to lower unit costs through fewer indexings and less scrap, supporting a demonstrable return on tooling investment over production cycles.
