CNMA 120408 FX105 Tungaloy indexable turning insert — 80° rhombic, with cylindrical hole

CNMA120408 FX105 is a rhombic, ISO-compliant indexable insert designed for ISO-standard turning applications and robust edge stability

• ISO-standard rhombic geometry 80°
• Carbide grade FX105 for long life
• 0.8 mm corner radius for robust cutting
• With cylindrical hole for secure clamping

Productivity through consistent edge life and wear resistance

The CNMA120408 FX105 insert pairs a purpose-engineered geometry with a wear-resistant carbide grade FX105, delivering predictable tool life under typical turning conditions. The 80° geometry provides a balanced cutting edge that supports both external and internal turning while reducing deflection in light to medium-duty cuts. As a result, production cycles become more reliable and downtime for insert changes is reduced, contributing directly to throughput and process efficiency.

Fast, repeatable clamping for workshop efficiency

Designed to the ISO specification, the rhombic indexable insert ensures compatibility with standard holders when matching form, clearance angle and tolerance class. The rhombic shape, cylindrical hole and a plate thickness of 4.76 mm allow firm seating and repeatable positioning, which lowers setup time and maintains cutting geometry between indexings. Clear dimensional conformity means replacement is straightforward and repeatable, supporting lean changeovers on the shop floor.

Application scope and practical machining advice

The insert, made from cemented carbide and supplied without a chipbreaker, is intended for general turning; select a chipbreaker and grade appropriate to the workpiece material and cutting strategy. The corner radius 0.8 mm offers a compromise between edge strength and surface finish, suitable for medium finishing and light roughing. For materials and parameters beyond standard turning tasks, consult the technical team to match insert geometry and clamping to the machining stability required.

FAQ

Which holders are compatible with this CNMA120408 insert?
Compatibility is determined by the holder form, clearance angle, tolerance class, fastening type, size and thickness; the CNMA120408 FX105 fits ISO-standard holders designed for CNMA inserts.

Is the insert coated or uncoated?
The CNMA120408 FX105 is supplied as a cemented carbide insert in the FX105 grade; coating details are not specified for this item and should be confirmed if coating is required.

What cutting tasks suit a 0.8 mm corner radius?
A 0.8 mm corner radius offers increased edge strength for light roughing and medium finishing, balancing durability and surface quality in typical turning operations.

Can this insert be used for internal turning?
Yes, the rhombic geometry and ISO conformity make the insert suitable for both external and internal turning when paired with an appropriate holder and machining strategy.

Why is there no chipbreaker on this insert?
This variant is offered without a chipbreaker to allow selection of the optimal chip control geometry for the specific workpiece material and process; choose a matching chipbreaker or insert variant as required.
