CNGA 120408 TZ120 indexable turning insert — rhomboid CNGA for Turning by Tungaloy

The CNGA120408 TZ120 is an ISO-standard rhomboid indexable insert engineered for external and internal turning, providing a balance of wear resistance and edge stability for productive metalcutting operations.

• ISO CNGA form, 80° included angle
• TZ120 grade for wear resistance and toughness
• 0.8 mm corner radius for controlled finish
• Rhomboid insert with central cylindrical hole

Precise ISO geometry for consistent turning performance

The ISO geometry and 80° included angle of this rhomboid insert ensure repeatable toolpaths and stable contact during turning cycles. The form and clearance parameters govern holder compatibility, so selection of the matching insert seat and clamping hardware is decisive for process stability. The ISO CNGA120408 designation identifies the standardised contour and tolerance class, which simplifies tool management across different machines and reduces setup variation. As a result, cycle-to-cycle surface consistency and predictable tool life are supported by the insert’s basic design.

Durable cutting grade for longer tool life and edge integrity

The TZ120 grade, supplied by Tungaloy as a proprietary carbide formulation, combines wear resistance and adequate toughness to maintain the cutting edge in mixed cutting conditions. This grade complements the insert geometry by resisting abrasive wear while preserving edge stability under intermittent loading, which is beneficial for batch production and varied workpiece materials. The carbide substrate provides the hardness necessary for abrasion control while the grade’s balanced properties reduce the likelihood of premature chipping, supporting longer productive periods between insert changes.

Secure clamping and finishing potential with a small corner radius

The rhomboid shape with a cylindrical hole provides reliable clamping and repeatable seating in suitable CNGA holders; compatibility depends on form, free angle, tolerance class, fastening and thickness. The 0.8 mm nose radius strikes a compromise between finishing quality and edge strength—smaller radii improve surface finish, while slightly larger radii increase robustness under higher feed or interrupted cuts. With a 4.76 mm thickness and 12 mm nominal size, the insert offers stable support in the pocket and straightforward orientation for external and internal turning operations where a controlled surface finish and dependable edge life are required.

FAQ

What turning operations suit this insert best?
The CNGA120408 TZ120 Tungaloy insert is designed for general external and internal turning applications where a balance of wear resistance and edge stability is required.

How is holder compatibility determined for this insert?
Compatibility depends on the insert form, clearance angle, tolerance class, fastening method, size and thickness; ensure the selected CNGA holder matches those parameters for correct seating of the CNGA120408 TZ120 insert.

What does the TZ120 grade provide compared with other grades?
TZ120 is formulated to combine wear resistance with toughness, offering stable edge performance and extended tool life in mixed cutting conditions typical of turning applications.

Does the absence of a chipbreaker limit the insert’s use?
The insert is supplied without a chipbreaker, which is common for finishing or where process and toolholder geometry are optimised for controlled chip evacuation; for heavy chip-forming operations a chip control variant may be preferable.

How does the 0.8 mm corner radius affect surface finish and strength?
A 0.8 mm nose radius provides a compromise: it enhances edge strength compared with very small radii while still supporting good surface finish at moderate feeds.
