CNGA120404 BX360 Tungaloy ISO indexable turning insert – CBN for hardened steels

The CNGA120404 BX360 is an ISO rhombic indexable turning insert designed for finishing and hard-turning of hardened steels, offering a consistent cutting geometry for stable machining.

• ISO rhombic insert CNGA120404
• CBN grade BX360 for hardened steels
• 0.4 mm corner radius for fine finishing
• Cylindrical hole, compatible with standard holders

Precise finishing on hardened components

The rhombic indexable insert delivers consistent surface quality when finishing heat-treated parts. With a cubic boron nitride (CBN) cutting material in grade BX360, the insert is optimised for the high hardness and abrasive nature of hardened steels, enabling lower tool wear and predictable tool life. The modest corner radius and the fine geometry support tight tolerance work and minimise rework, which reduces cycle variability and improves overall process reliability.

ISO compatibility reduces tooling complexity

Designed to the ISO specification for turning inserts, the unit integrates smoothly with common external holders and boring bars. The ISO conformity of form, relief angle, tolerance class, fastening and size ensures straightforward interchangeability with established tooling systems, simplifying inventory and holder selection. The cylindrical hole and standard mounting dimensions allow secure clamping and stable seating, which is essential for repeatable turning operations.

High abrasion resistance and process stability

The BX360 grade provides a robust cutting edge in high-wear applications, delivering improved edge stability during prolonged finishing passes. This leads to fewer interruptions for insert changes and steadier surface integrity over batch production. The carbide substrate combined with the CBN cutting layer offers the balance needed for demanding end-of-line machining, with reduced susceptibility to thermal degradation compared with traditional ceramic grades.

Application guidance for reliable results

For external and internal turning of quenched and tempered steels, select the insert geometry and grade to match the component hardness and machine rigidity. The absence of a dedicated chipbreaker on this type of insert favours controlled finishing cuts with consistent chip flow; for interrupted cuts or heavy roughing, complement the tooling package with appropriate chip management measures. Employ moderate feed rates and stable clamping to exploit the insert’s strengths in repeatable, high-quality finishing.

FAQ

What materials is this insert primarily intended for? The CNGA120404 BX360 Tungaloy indexable insert is primarily intended for hardened steels and, depending on execution, can also be used for some cast iron applications.

Is the insert compatible with standard ISO external holders? Yes. The ISO-conforming geometry of the CNGA120404 ensures compatibility with standard external holders and boring bars designed for CNGA-style inserts.

What does the BX360 grade mean in practice? BX360 denotes a CBN-based cutting grade optimised for high hardness and wear resistance, providing stable performance during finishing of hard materials.

How does the absence of a chipbreaker affect machining? With no dedicated chipbreaker, the insert is best used for controlled finishing cuts where chip form and evacuation are managed by tooling setup and cutting parameters.

What is the manufacturer SKU and article number for ordering? The manufacturer SKU is TUN6801830 and the article number is 6801830; these identifiers refer to the CNGA120404 BX360 Tungaloy indexable insert.
