CNMG120404 KS05F Tungaloy indexable insert — Turning, rhombic 80°

The CNMG120404 KS05F Tungaloy indexable insert is an ISO-standard rhombic turning insert designed for external and internal turning where resistance to wear and stable cutting edges are required.

Rhombic 80° ISO geometry
KS05F Tungaloy carbide grade
0.4 mm corner radius
Double-sided chipbreaker, with cylindrical hole

High wear resistance for extended machining cycles

The KS05F grade, supplied by Tungaloy, combines a wear-resistant carbide substrate with a geometry tuned for stable cutting-edge life. This construction promotes consistent wear resistance and reduces the frequency of insert changes, which in turn improves machine uptime and lowers tooling costs per part. The double-sided chipbreaker helps maintain predictable chip formation on interrupted and continuous cuts, while the 0.4 mm corner radius supports edge strength without compromising finish in many turning tasks. The combination of material and geometry is particularly effective in production environments seeking repeatable results and lower tool consumption.

ISO compatibility that simplifies toolholder selection

Designed to the ISO designation CNMG120404, the insert fits holders that match the defined form, relief angle and tolerance class. The ISO conformity ensures straightforward interchangeability across standard indexable systems and makes tool changeover quicker on the shop floor. The 0° free angle and 80° included angle are important parameters when checking holder compatibility; inserts with a cylindrical hole require matching clamping elements for secure fixing. Attention to these measurable specifications reduces set-up time and maintains cutting accuracy across batches.

Productivity gains through reliable chip control and material coverage

For turning applications, selecting the correct chipbreaker and the KS05F grade supports chip evacuation and surface quality, which directly contributes to higher productivity. The insert suits a wide range of turning tasks — external and internal — where a balance of toughness and wear resistance is needed. Practical benefits include fewer interruptions for insert indexing and better predictability in cycle times. Backed by Tungaloy’s manufacturing consistency, the insert provides a reliable basis for process planning and helps achieve stable production ramps in both small-batch and high-volume operations.

FAQ

What materials is this insert suitable for?
The CNMG120404 KS05F Tungaloy indexable insert is engineered for general turning tasks where a balance of wear resistance and toughness is required; material selection should match the KS05F grade properties and the chosen chipbreaker.

How is the insert fixed in the holder?
This insert features a cylindrical hole and must be used with a compatible clamping system and holder that conform to the CNMG ISO geometry.

Can the insert be used for both external and internal turning?
Yes, the CNMG120404 KS05F insert is specified for both external and internal turning operations when paired with the appropriate holder and cutting parameters.

What benefit does the 0.4 mm corner radius provide?
A 0.4 mm corner radius increases edge strength for interrupted cuts and higher feed rates while still allowing acceptable surface finishes in many turning applications.

Is the KS05F grade suitable for high-volume production?
The KS05F grade from Tungaloy is designed to offer consistent performance and wear resistance, supporting longer machining cycles and predictable tool life in volume production.
