SPGN120308 BX360 — ISO turning insert (CBN) for turning, Tungaloy

A SPGN120308 BX360 indexable insert designed for precision external and internal turning, optimised for hard turning of hardened steels and, depending on variant, cast iron.

• SPGN120308 BX360 CBN grade
• ISO‑standard square insert 12 mm
• 11° relief angle for stable cutting
• 0.8 mm corner radius for finish turning

Reliable finishing on hardened components

The BX360 grade employs cubic boron nitride (CBN) to deliver wear-resistant cutting edges suited to high-hardness finishing. CBN is a superabrasive optimised for machining hardened steels, offering thermal stability and reduced flank wear compared with conventional abrasives. As a result, the insert maintains dimensional accuracy over longer tool life, which supports predictable cycle times and fewer interruptions for tool changes.

Seamless integration with ISO toolholders

The insert follows the ISO geometry standard, so compatibility with existing holders is determined by matching the form, 11° relief, tolerance class, fastening and thickness. This standardisation simplifies tool setup and reduces inventory complexity: the square insert mounts in common external holders or boring bars, while the system concept—insert, holder, shim/clamp and replacement screws—ensures repeatable clamping and consistent cutting performance.

Geometry engineered for surface quality and stability

A square plate with a 0.8 mm corner radius produces a durable cutting line for fine finishing without sacrificing edge strength. The 3.18 mm plate thickness adds rigidity against chatter and deflection, supporting stable cutting at light feedrates required for final passes. The combination of 90° insert orientation and the corner radius provides the option of perpendicular cuts with excellent surface finish or inclined approach for more aggressive material engagement.

Application scope and practical benefits for workshops

Designed primarily for turning, the insert suits both external and internal operations where hardened workpieces require consistent surface integrity. The absence of an integrated chipbreaker means the grade relies on process parameter optimisation and holder geometry for chip control; selecting the appropriate holder and cutting data yields efficient chip evacuation and maximises the BX360 advantage. The overall effect is enhanced throughput, reduced rework and stable tool life in series production.

FAQ

What materials is this insert suitable for?
The SPGN120308 BX360 insert (Tungaloy indexable turning insert, SKU 6807071-Tungaloy) is formulated primarily for hardened steels and, depending on the variant, can be applied to certain grades of cast iron for finish operations.

How does the BX360 grade improve tool life?
The BX360 CBN grade provides high wear resistance and thermal stability; when used with the correct holder and cutting data, the insert sustains edge integrity and extends effective tool life in hard turning cycles.

Is this insert compatible with standard ISO holders?
Yes. The insert conforms to ISO geometry; compatibility depends on matching the form, relief angle, tolerance class, fastening and thickness to the holder specification.

Which cutting parameters are recommended for finishing?
For finishing hardened components, low to moderate feeds with light depths of cut are advised; the square geometry and 0.8 mm corner radius favour fine surface quality while the 3.18 mm thickness helps maintain stability.

Does the insert include a chipbreaker?
This variant is supplied without a chipbreaker; chip control is achieved via holder selection and cutting conditions tailored to the workpiece and machine setup.
