SNGA120402-QBN BX360 turning indexable insert by Tungaloy — ISO geometry

SNGA120402-QBN BX360 is an ISO-format square indexable insert for precision turning, optimised for finishing hardened steels and, where applicable, cast iron.

• CBN grade BX360 for hardened steels
• ISO SNGA geometry for standard holders
• 0.2 mm corner radius for precise finishes
• Cylindrical hole for secure clamping

High-performance cutting for hardened components

The use of CBN in the BX360 grade provides high wear resistance and thermal stability when machining hardened steels, reducing flank wear in demanding end‑turning operations. This translates into longer uninterrupted tool life and fewer insert changes, which contributes to lower overall process costs. The brittle yet heat‑stable nature of the cutting material enables fine, consistent surface finishes in the final pass, so there is less need for secondary grinding.

Predictable geometry and secure clamping for repeatable results

Built to the ISO SNGA form, the insert delivers a defined seating datum and repeatable orientation in appropriately rated toolholders. The SNGA120402-QBN configuration pairs a square outline with a 90° included angle and 0° clearance, while the 4.76 mm thickness and 0.2 mm corner radius ensure mechanical stability under interrupted or stable cuts. A cylindrical hole provides positive clamping and simplifies index changes, reducing set‑up time and improving batch consistency.

Application guidance: finishing, process stability and economy

With the QBN chipbreaker, this insert is optimised for finishing passes where surface integrity and dimensional accuracy are priorities; the geometry controls chip form while preserving the strong CBN cutting edge. Depending on the specific variant, the grade also tolerates some cast iron operations, but the principal advantage is in machining high‑hardness steels where abrasive wear is the limiting factor. When combined with stable tooling and correct cutting data, the result is a reliable, economical finishing process that minimises scrap and rework.

FAQ

What materials is this insert designed for?
The Tungaloy SNGA120402-QBN BX360 insert is primarily designed for hardened steels and, dependent on the variant, can also be used for certain cast iron finishing applications.

What advantages does the BX360 CBN grade provide?
BX360 CBN gives improved wear resistance and thermal stability compared with carbide in high‑hardness turning; this yields longer tool life and more consistent surface quality when finishing hardened parts.

Is the SNGA geometry compatible with standard holders?
Yes, the ISO SNGA120402-QBN form is compatible with ISO‑rated holders; correct seating depends on matching form, relief angle, tolerance class, fastening and thickness.

Which chipbreaker should be selected for fine finishes?
The QBN chipbreaker fitted to this insert is recommended for finishing operations where chip control and surface integrity are required.

How can process stability be maximised with this insert?
Pair the insert with a rigid, vibration‑damped holder and appropriate cutting data; the combination of BX360 CBN cutting material and secure clamping produces repeatable results and reduces rework.
