CNMG120408 AH120 Tungaloy indexable turning insert — PVD-coated carbide, 0.8 mm corner radius

CNMG120408 AH120 Tungaloy-Wendeplatte is an ISO-standard indexable insert intended for external and internal turning, designed for process-secure cutting where a sharp edge and high wear resistance are required.

• ISO-standard CNMG 80° rhombic geometry
• PVD-coated carbide AH120 for wear resistance
• 0.8 mm corner radius for stable cutting
• Double-sided chipbreaker with centre hole

Consistent cutting performance that keeps production running

The combination of a PVD-coated surface and the AH120 carbide grade provides a balance between abrasion resistance and edge toughness that contributes to longer intervals between tool changes. The 80° CNMG geometry and 0.8 mm corner radius deliver predictable contact conditions at the tool tip, which helps maintain dimensional stability on face and axially oriented cuts. These characteristics reduce scrap rates and support steady cycle times in batch and series production.

Longer edge life and process security through optimised design

A PVD coating enhances resistance to abrasive wear while the substrate grade resists chipping under intermittent loads; together they increase effective cutting life and process security. The insert’s double-sided chipbreaker lets the same part be reused after indexing, which reduces tooling costs per produced component. Selecting the appropriate chipbreaker and grade for the workpiece material and cutting conditions yields measurable productivity gains and fewer unscheduled interventions.

Reliable mounting and ISO compatibility for flexible tool set-ups

The insert conforms to the ISO series for indexable turning plates; compatibility with a holder is determined by form, relief angle, tolerance class, fastening style, size and thickness. The cylindrical centre hole and standard dimensions make it straightforward to fit in a matching external holder or boring bar, and replacement screws, seats or clamping sets complete a secure system. Clear reference to holder geometry aids set-up repeatability and reduces alignment time at the machine.

Practical application scope and recommended use cases

Designed specifically for turning operations, the insert is appropriate for both external and internal turning where a sharp, process-secure cutting edge is required. The grade is suited to applications that demand a combination of wear resistance and resistance to chipping; for best results, pair the insert with a holder offering stable support and choose cutting parameters that match the material and machining conditions. This approach ensures consistent surface finish and reliable tool life.

FAQ

What materials is this insert suitable for?
The CNMG120408 AH120 insert is a PVD-coated carbide grade meant for demanding turning tasks; the AH120 grade is designed to provide a balance of wear resistance and edge strength suitable for a wide range of workpiece materials when the correct chipbreaker and cutting data are chosen.

How is the insert mounted to a toolholder?
Mounting is via the cylindrical centre hole and the ISO CNMG seating geometry; compatibility depends on holder form, relief angle, tolerance class, fastening method, size and thickness as specified for ISO indexable turning plates.

Can the insert be used on both external and internal turning operations?
Yes, the insert is intended for both external and internal turning; its 80° rhombic geometry and 0.8 mm corner radius provide versatility for a variety of turning applications.

What benefits does the AH120 grade offer compared with uncoated grades?
The AH120 PVD-coated grade increases abrasive wear resistance and helps maintain a sharp cutting edge under mixed cutting conditions, offering more consistent tool life and improved process security compared with uncoated counterparts.

Is the insert reversible and economical for series production?
The insert features a double-sided chipbreaker and indexable geometry, allowing reversal after one edge is used; this contributes to economical tooling costs and reduced downtime in series production.
