CNGA 120408 BX360 Tungaloy insert — ISO turning insert, CBN for hardened steels

A CNGA120408 BX360 Tungaloy insert designed for precision external and internal turning of hardened steels and hard finishing operations.

• CBN grade BX360 for high wear resistance
• ISO‑format rhombic insert, size 12
• 0.8 mm nose radius for fine finishing
• Supplied without chipbreaker, cylindrical hole

Longer tool life and consistent finishing for hardened components

The BX360 grade, based on cubic boron nitride (CBN), is formulated for the demands of high‑hardness machining, offering superior wear resistance and edge stability compared with conventional grades. This results in extended tool life and more consistent component surfaces during end or finish turning. The combination of a hard cutting material and a stable geometry reduces rework and increases productivity where repeatability is essential.

ISO compatibility and secure clamping for reliable process control

The insert follows ISO plate geometry and the CNGA rhombic form, enabling straightforward selection of compatible external holders or boring bars. The cylindrical hole and standard thickness (4.76 mm) ensure secure clamping and predictable seating, while the specified tolerance class and form control the fit to the pocket. Correct matching of holder form, clearance and fastening translates into stable cutting conditions and fewer interruptions on the shop floor.

Application notes for turning without a chipbreaker

Delivered without chipbreaker, this insert is intended for finishing cuts on hardened steels; the lack of a chipformer supports formation of continuous, easy-to-manage chips in many finishing setups. For roughing or interrupted cuts, a different geometry or an insert with an integrated chipbreaker should be selected. Speeds and feeds must be adapted to the CBN grade and part material to exploit the insert’s strengths: higher cutting speeds and modest feedrates commonly produce the best surface integrity and tool life.

System composition, handling and process advantages

The recommended system comprises an ISO plate, a matching external holder or bar, a correct underlay/clamping set and replacement screws. Installation is simple when pocket fit and clearance are verified, and the 0.8 mm nose radius supports fine surface finishes while still offering robustness against minor runout. As a Tungaloy product, the insert benefits from manufacturing consistency that aids predictable tool changes and reliable batch processing, reducing downtime and raising overall process efficiency.

FAQ

Which materials is this insert designed for?
The CNGA120408 BX360 Tungaloy insert is specified primarily for hardened steels and, depending on the workpiece, can be used for certain cast‑iron finishing operations.

Is a chipbreaker included with the insert?
No — the CNGA120408 BX360 insert is supplied without chipbreaker, making it suitable for finish turning where chip control is managed by cutting parameters and tool set‑up.

Which holder type is compatible with this insert?
Holders conforming to the ISO CNGA pocket and matching the 12 mm plate size and 4.76 mm thickness are compatible; ensure pocket form, tolerance and fastening suit the Tungaloy insert SKU 6801837‑Tungaloy.

What cutting geometry supports the best surface finish?
The 0.8 mm nose radius and the 0° clearance produce a fine surface in finishing passes; modest feeds combined with the BX360 CBN grade typically yield the best surface integrity.

How does this insert contribute to process stability?
The BX360 CBN composition and the ISO rhombic format provide a stable cutting edge and predictable seating, which reduces tool changes and improves batch consistency when correctly applied.
