CNGA120412 BX360 Tungaloy turning insert (CNGA 120412, BX360) by Tungaloy

A CNGA‑form ISO turning insert in BX360 CBN grade for high‑hardness finishing and heavy wear resistance in turning operations.

• CBN grade BX360 for hardened steels
• ISO‑standard CNGA geometry
• Radius 1.2 mm for robust edge strength
• Rhombic 80° form with central hole

High‑performance material for finishing hardened steels

The BX360 grade combines cubic boron nitride (CBN) as the cutting material with a carbide substrate to deliver consistent performance in high‑hardness turning. As a superhard abrasive, CBN offers superior wear resistance and thermal stability compared with conventional carbide grades, which translates into longer edge life and stable dimensional results on hardened steels. For finishing passes where surface quality and tool life are decisive, this material choice reduces downtime and rework while maintaining productivity.

ISO CNGA geometry optimises clamping and cutting stability

The rhombic CNGA shape with an included angle of 80° and a 1.2 mm nose radius provides a reliable compromise between edge strength and accessibility for external and internal turning. The insert is supplied with a cylindrical central hole for positive clamping and a thickness of 4.76 mm, ensuring mechanical stability in common ISO holders. Compatibility with a toolholder is determined by form, clearance angle, tolerance class, mounting and size; selecting matching components guarantees repeatable seating and consistent cutting conditions.

Process benefits, system setup and recommended use

Designed for turning applications and intended for wear‑intensive finishing of high‑hardness components, this insert supports a productive machining sequence when paired with an appropriate holder, shim and fastening set. Because the insert is produced to ISO norms, integration into existing tool systems is straightforward, enabling predictable chip formation and surface finish when the correct chipformer and grade are chosen. The absence of a dedicated chipbreaker in this specification requires selection of holder geometry and cutting parameters to control chips during heavy finishing.

FAQ

What materials is this insert intended for? The CNGA120412 BX360 insert is intended primarily for hardened steels and, depending on the variant, can be used for certain cast irons; the BX360 CBN grade is optimised for high‑hardness finishing.

Which holder type is required for this geometry? A secure ISO‑compatible turning holder for CNGA‑form inserts with a cylindrical central mounting is required; ensure the holder matches the insert size, thickness and clearance angle for correct clamping.

Does this insert include a chipbreaker? No, the specified item is supplied without a chipbreaker; chip control must be achieved by choosing the appropriate holder geometry or cutting parameters.

How does the 1.2 mm radius affect machining? The 1.2 mm nose radius improves edge strength and contributes to a stable finish on hardened components, while balancing the achievable surface roughness for finishing cuts.

Is the BX360 grade suitable for continuous production runs? Yes, the BX360 CBN grade is engineered for wear‑intensive finishing, offering extended tool life and process stability in repeated production.
