CNGG 120404 KS05F indexable insert for turning — Tungaloy, 80° rhombic, carbide

CNGG 120404 KS05F is an ISO-standard rhombic indexable insert designed for external and internal turning where stable cutting edges and repeatable performance are required.

• ISO-standard CNGG geometry
• KS05F Tungaloy grade for wear resistance
• 80° rhombic shape with 0.4 mm radius
• Double-sided insert with cylindrical hole

Reliable edge life and predictable process performance

The insert combines the KS05F Tungaloy grade with a carbide substrate to deliver enhanced wear resistance and sustained cutting-edge stability during medium to heavy turning operations. The built-in double-sided chipbreaker promotes consistent chip control, reducing the need for frequent tool changes and supporting steady cycle times. Choosing a grade that balances toughness and hardness means the cutting edge resists chipping while maintaining acceptable flank wear progression, which translates directly into fewer interruptions on the shop floor and improved overall equipment effectiveness.

Straightforward compatibility with ISO toolholder systems

Engineered to the ISO code 120404, this rhombic insert fits standard CNGG toolholders when matching the form, relief angle, tolerance class, fastening method, size and thickness. The 80° geometry provides good shoulder strength and versatility for external and internal turning, while the cylindrical hole ensures secure clamping. The insert’s 4.76 mm thickness and 12 mm size offer a robust cutting edge, and the 0° relief angle supports a wide range of feeds and depths of cut. This clear ISO alignment simplifies procurement and inventory management across multiple machines and tool families.

Practical handling and machining benefits for workshop use

With a 0.4 mm radius, the insert offers a defined corner for reliable finishes and predictable toolpath outcomes when profiling or shoulder turning. The rhombic shape allows indexing of multiple cutting edges, extending life per insert and reducing tooling costs in high-volume runs. For operators less familiar with insert grades, the combination of Tungaloy’s engineered composition and the insert’s chip control features provides a forgiving cutting behaviour that aids consistent surface quality and reduces the need for constant parameter adjustments. When optimised cutting data are applied, productivity improves while part quality remains stable.

FAQ

What materials is this insert suited for?
The CNGG120404 KS05F Tungaloy indexable insert is designed for general turning applications; the KS05F grade provides a balance of wear resistance and toughness suitable for a broad range of steels and mixed-material jobs.

How does the chipbreaker affect machining?
The double-sided chipbreaker on the CNGG120404 helps produce controlled chips and steady metal removal, improving surface quality and reducing cycle interruptions associated with poor chip formation.

Can the insert be used in both external and internal turning?
Yes, the rhombic geometry and 80° insert angle make the CNGG120404 appropriate for both external and internal turning when paired with the correct ISO-compatible holder.

How many cutting edges are available per insert?
The CNGG120404 is double-sided and indexable; rotating the insert exposes fresh cutting edges, which extends life per insert and reduces tooling consumption.

Which specifications should be matched on the toolholder?
Holder compatibility for the CNGG120404 depends on insert form, relief angle, tolerance class, fastening method, size and thickness; ensure the holder matches the ISO CNGG geometry and the 120404 code.
