CNMG 120408 AH6225 turning indexable insert by Tungaloy — PVD-coated carbide, 80° rhombic geometry

CNMG120408 AH6225 is an ISO-spec rhombic insert optimised for turning applications, offering a sharp yet robust cutting edge for midspeed operations.

PVD-coated carbide grade AH6225
Designed for rostfreie Stähle
Rhombic 80° geometry, 0.8 mm radius
Double-sided chipbreaker, with hole

Consistent edge life and reliable mid-range performance

The AH6225 grade combines a PVD-coated surface with a wear-resistant carbide substrate to provide a durable, sharp cutting edge that tolerates fluctuating cutting conditions. For turning operations of rostfreien Stahl the engineered coating improves thermal resistance and reduces flank wear, which translates into fewer insert changes and more predictable cycle times. This results-oriented design supports production stability and helps maintain component tolerances during medium-duty external and internal turning.

Broad compatibility with ISO turning systems for secure clamping

Designed to the ISO series for indexable inserts, the geometry and dimensions ensure compatibility with common external holders and boring bars when matched by shape, clearance angle, tolerance class, fastening method, size and thickness. The 80° lead angle and rhombic form offer a balance between strength and accessibility in confined cuts, while the 0° clearance angle, 12 mm inscribed size and 4.76 mm thickness simplify selection of a matching toolholder. Correct pairing reduces chatter and improves repeatability in batch production.

Practical workshop advantages and chip control for efficient machining

The double-sided design and integrated chipbreaker provide economic use of both cutting edges and aid chip fragmentation under varying cutting depths and feeds. The 0.8 mm corner radius supports stable turning of medium cross-sections and helps achieve consistent surface quality without compromising edge strength. Where high process reliability is required, the combination of the insert’s PVD coating and grade chemistry offers improved wear resistance and longer tool life, which together lower tooling overhead and simplify machining planning.

FAQ

Which turning tasks suit this insert best?
This CNMG120408 AH6225 indexable insert from Tungaloy is intended for medium-duty external and internal turning, especially when machining rostfreien Stahl where a balance of sharpness and edge stability is needed.

How is chip control achieved with this insert?
The double-sided chipbreaker integrated into the insert geometry promotes fragmentation across a range of feeds and depths; the AH6225 grade and PVD coating further support stable cutting and consistent chip formation.

Can the insert be used with standard ISO holders?
Yes, the insert follows ISO dimensions; successful fit requires matching the holder by form, clearance angle (0°), tolerance class, fastening method, size and thickness to ensure secure clamping.

What are the key dimensional data to check before ordering?
Verify the ISO designation CNMG120408, inscribed size 12 mm, thickness 4.76 mm, corner radius 0.8 mm and the 80° geometry to confirm compatibility with the chosen toolholder and application.

Is AH6225 suitable for finishing passes?
AH6225 is a universal grade optimised for rostfreie Stähle with a sharp yet stable edge; it performs well in medium cuts and can be used for semi-finish and finishing depending on cutting parameters and machine stability.
