CNGG120408 KS05F — Indexable turning insert (rhombic 80°, 0.8 mm radius) | Tungaloy

The CNGG120408 KS05F is an ISO‑compliant rhombic indexable insert engineered for external and internal turning applications, compatible with appropriately dimensioned holders and clamping systems.

• ISO‑compliant rhombic insert 12 mm
• KS05F Tungaloy grade for wear resistance
• 0.8 mm nose radius for precise profiling
• Double‑sided chipbreaker with cylindrical hole

Geometry that delivers predictable cutting performance

The rhombic 80° geometry combined with a 0° clearance creates a robust seating and approach angle that is well suited to a wide range of turning tasks. The defined 0.8 mm nose radius supports accurate contouring and repeatable profile work, while the ISO conformity ensures straightforward interchangeability with standard indexable holders. Because compatibility depends on holder form, relief angle, tolerance class, clamping method, size and thickness, this geometry reduces uncertainty at setup and helps maintain consistent component tolerances during production.

A Tungaloy grade chosen for productivity and tool life

The KS05F cutting grade is formulated to balance wear resistance and edge toughness, extending service life under mixed machining conditions. Combined with the insert's double‑sided chipbreaker, the grade helps control chip form and heat at the cutting edge, which supports longer periods between indexings and lowers tooling costs per part. For operations seeking economical, repeatable results, this composition offers a pragmatic route to higher process uptime and steady surface quality.

Precise dimensions for reliable system integration

With a nominal size of 12 mm and a plate thickness of 4.76 mm, the insert fits standard ISO‑type turning systems where stable clamping is required. The inclusion of a cylindrical hole facilitates positive positioning and consistent clamp engagement; the specified dimensions aid in achieving repeatable concentricity and reduced set‑up time. Clear, measurable parameters make it easier to document tooling data in CAM systems and tool libraries, supporting quicker changeovers and reliable batch production.

Practical guidance for application and process optimisation

Designed for turning, the insert performs best when the chipbreaker and grade are selected to match workpiece material, cutting strategy and machine rigidity. The ISO format allows simple comparison of alternative geometries and grades when process conditions change. Where higher stability is required, the robust carbide construction combined with KS05F's balanced properties helps maintain edge integrity and surface finish. If additional machining data is needed, technical consultation is recommended to align insert choice with spindle power, feed strategy and desired surface requirements.

FAQ

What holder characteristics determine compatibility with this insert?
Compatibility is determined by holder form, relief angle, tolerance class, clamping method, size and plate thickness; the CNGG120408 KS05F insert requires a matching ISO‑compliant turning holder for correct seating and secure clamping.

Which applications are best suited to the KS05F grade?
The KS05F Tungaloy grade in the CNGG120408 insert is aimed at turning applications where a balance of wear resistance and edge toughness is needed, providing stable performance across varied machining conditions.

How does the double‑sided chipbreaker affect tool life?
A double‑sided chipbreaker offers two cutting edges per indexed position and improved chip control, which can increase cutting intervals and reduce tooling cost per component when using the CNGG120408 KS05F insert.

Can the 0.8 mm nose radius be used for finishing passes?
Yes; the 0.8 mm radius provides a compromise between profile definition and edge strength, making the insert suitable for medium finishing and profiling operations while retaining edge stability.

Which identification numbers should be referenced when ordering?
Reference the designation CNGG120408 KS05F and the article number 6934785 or manufacturer SKU TUN6934785 to ensure the correct Tungaloy indexable insert is supplied.
