SNGN120412 BX360 ISO turning insert for hardened steels — Tungaloy

A SNGN120412 BX360 indexable turning insert engineered for finishing hardened steels and intended for ISO-standard turning toolholders in external and internal turning operations.

• CBN grade BX360 for hardened steels
• ISO SNGN120412 geometry, square form
• 1.2 mm corner radius for fine finishing
• 0° clearance angle, suited for finishing

Precise finishing for hardened components with CBN technology

The use of cubic boron nitride (CBN) in the BX360 grade is tailored to the demands of hard-machining. This cutting material offers elevated wear resistance and a stable cutting edge, which translates into longer tool life and more predictable tool-change intervals. For shops machining quenched or case-hardened parts, the combination of a square ISO geometry and a CBN cutting grade supports a consistent surface finish with fewer dressing cycles. Compatibility with ISO holders is defined by form, clearance angle, tolerance class, fixing method, size and thickness, ensuring straightforward integration into standard turning setups.

Geometry and edge design that enhance process stability

The ISO SNGN form provides a robust platform for finishing cuts: the square plate with a 90° included angle permits rigid clamping and repeatable orientation, while the 1.2 mm corner radius balances edge strength with the ability to achieve fine surface quality. A 0° clearance angle reduces radial runout sensitivity during light finishing passes. The insert is supplied without a chipbreaker, so selection of a matching holder and cutting parameters is essential to control chip flow. As a system, the insert, suitable outer holder or boring bar, shim/clip and replacement screws form a predictable setup that minimises downtime and supports stable cycle times.

Application guidance for production-oriented workshops

Designed primarily for turning, the insert is suited to external and internal finishing of hardened steels, and — depending on the specific grade version — may be applicable to certain grades of cast iron. When adopting the BX360 grade, choose cutting speeds and feeds optimised for CBN to exploit its longer life and consistent edge geometry; lower feed rates and stable clamping reduce the risk of tool fracture and ensure reproducible component quality. Indexing the plate at scheduled intervals and keeping spare inserts to hand increases process uptime. Shops seeking predictable finishing performance in serial production will benefit from the grade’s wear characteristics and the ISO-compliant geometry of the insert.

FAQ

What materials is the insert suited for?
The BX360 CBN grade is designed for hardened steels and, depending on the version, can be used for selected cast iron applications; consult the supplied technical guidance for specific alloys.

How does the SNGN120412 geometry affect holder choice?
The ISO SNGN120412 geometry requires a matching square insert seat in an external holder or a compatible boring bar; compatibility is determined by form, clearance angle, tolerance class, fixing method, size and thickness.

Is there a chipbreaker on this insert?
This insert is supplied without a chipbreaker, so chip control must be achieved via choice of holder geometry and cutting parameters.

What is the corner radius and how does it influence finish?
The corner radius is 1.2 mm; this radius offers a balance between edge strength and the ability to achieve fine surface finishes in finishing operations.
