CNMG 120404 AH6235 indexable turning insert by Tungaloy — PVD-coated carbide, ISO CNMG form for turning

CNMG120404 AH6235 is an ISO rhombic indexable insert for turning, optimised for applications in stainless steel and suited to interrupted cuts where stable edge behaviour is critical.

• ISO CNMG geometry for general turning
• PVD-coated AH6235 grade for stainless steel
• 80° cutting angle with 0° clearance
• Double-sided insert with cylindrical hole

Consistent edge performance for demanding stainless applications

The CNMG120404 AH6235 insert combines a PVD coating with a tenacious carbide substrate to deliver consistent performance under the cyclic loads typical of turning stainless steel. The AH6235 grade is formulated to resist notch formation and chipping during interrupted cuts, reducing the frequency of index changes. For production environments where stable tool life and reduced scrap are priorities, this combination provides measurable gains in process reliability and component repeatability.

Geometry and clamping that support secure machining

The rhombic CNMG shape with an 80° cutting angle and 0° clearance promotes secure engagement in external and internal turning operations. The 0.4 mm corner radius supports a balanced compromise between edge strength and surface finish, while the 4.76 mm thickness ensures rigidity at the cutting edge. The insert’s cylindrical hole and standard ISO form enable compatibility with a wide range of external holders and boring bars when matched by form, relief angle, tolerance class, fastening method, size and thickness.

Application-focused features that simplify selection and increase uptime

The insert is double-sided, allowing economical indexable use and straightforward reorientation when one edge is worn. The doppelseitig chipbreaker (double-sided chip control) concept supports effective chip formation and evacuation on both cutting faces, which helps maintain consistent cutting forces and surface quality. Choosing the correct chipbreaker and grade for the workpiece material and machining stability reduces downtime and supports productive turning processes in workshops and production lines.

FAQ

What materials is this insert intended for?
The CNMG120404 AH6235 insert is specified for machining stainless steel and performs well in interrupted cutting conditions where notch resistance is required.

How does the AH6235 grade affect tool life?
The AH6235 PVD-coated carbide grade in this Tungaloy indexable insert provides improved notch and chipping resistance, which typically extends the effective tool life under cyclic loads.

Is the insert reversible and how many cutting edges are available?
The insert is double-sided, offering two usable cutting edges per side, which allows multiple indexing cycles before replacement is necessary.

Which holder features are required for compatibility?
Compatibility depends on holder form, free angle, tolerance class, fastening method, size and thickness; the CNMG geometry and cylindrical hole match standard ISO external holders and bores when these parameters correspond.

Can this insert be used for internal turning?
Yes, the insert’s geometry and rigidity from its 4.76 mm thickness make it suitable for both external and internal turning applications when paired with an appropriate boring bar or holder.
