SNGA 120412 BX360 ISO turning insert for turning — Tungaloy

The SNGA 120412 BX360 is an ISO‑standard square turning insert designed for external and internal turning operations, optimised for finishing of hardened steels and, depending on variant, cast iron.

*ISO‑standard square insert *CBN grade BX360 for hardened steels *90° geometry, 1.2 mm corner radius *Cylindrical hole for secure clamping

Consistent finishing on hardened components thanks to CBN technology

The BX360 designation identifies a CBN cutting material engineered for wear‑intensive finishing of high‑hardness workpieces. Cubic boron nitride provides superior abrasion resistance compared with conventional carbide grades, which translates into longer uninterrupted cut times and fewer insert changes. For precision finishing applications where surface integrity and dimensional stability are critical, the CBN composition delivers consistent edge retention and reduced regrinding frequency, improving overall process efficiency.

Stable clamping and geometry that support accurate shoulder turning

ISO‑standardisation of the insert ensures repeatable fitment with compatible holders; compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness. The square plate with a 90° corner and a 1.2 mm corner radius provides a compromise between strength and profile fidelity, suitable for defined shoulder faces and light profiling. The insert’s cylindrical hole allows secure axial clamping and precise location, while the 4.76 mm plate thickness contributes to rigidity under interrupted cuts, reducing chatter and improving surface finish.

Selection guidance for chip control and material pairing

This insert is supplied without an integrated chipbreaker, so the choice of chip control geometry and corresponding holder should match the workpiece material and machining strategy. The BX360 CBN grade is intended primarily for hardened steels and, depending on the specific variant, for some cast iron grades; softer non‑ferrous materials are generally not suitable for CBN cutting edges. Select holders and feed rates that favour continuous, low‑impact engagement to exploit the CBN edge‑retention benefits and to avoid thermal shock to the cutting zone.

Improved process security and predictable tool life for finishing cycles

Built on a cemented carbide substrate with a CBN cutting surface, this insert combines the mechanical support of the body material with the thermal and abrasive resistance of the CBN layer. The result is a predictable wear pattern and reduced risk of catastrophic flank failure in demanding finishing operations. For production lines focused on repeatability and low rework rates, the insert supports stable machining windows and contributes to lower overall tooling cost per component when matched to the correct holder and cutting parameters.

FAQ

Which materials is this insert designed to cut?
The SNGA 120412 BX360 insert from Tungaloy is designed primarily for the finishing of hardened steels and, depending on the specific execution, can also be suitable for cast iron.

Can the SNGA 120412 BX360 be used in standard ISO holders?
Yes; the ISO‑standard form guarantees compatibility with holders that match the insert’s form, size, thickness, clearance angle and fastening method.

Why choose a CBN grade like BX360 over conventional carbide for finishing?
CBN offers superior abrasion resistance and edge retention on hardened workpieces, which leads to longer continuous cutting periods and improved surface integrity compared with standard carbide inserts.

Is a chipbreaker included with this insert?
No; the SNGA 120412 BX360 is supplied without a chipbreaker, so chip control must be achieved via holder geometry or by selecting a matching chipbreaker insert where appropriate.

What clamping features ensure secure retention in the toolholder?
The insert has a cylindrical hole for axial clamping, combined with a square form and 4.76 mm thickness to ensure stable seating and reduced vibration during finishing passes.
