TNGA 160412 BX360 indexable turning insert for turning — Tungaloy, CBN grade

The TNGA160412 BX360 is an ISO triangular indexable insert designed for external and internal turning of hardened steels and, depending on specification, cast iron; it offers a robust clamping interface and is compatible with standard ISO holders.

• CBN grade BX360 for hardened steels
• ISO triangle 60° geometry
• 1.2 mm corner radius for fine finishing
• Cylindrical-hole design with secure clamping

High performance on hardened workpieces with consistent wear life

The TNGA160412 BX360 is engineered around the CBN cutting material and the BX360 grade to deliver sustained performance when machining high-hardness materials. The use of CBN ensures excellent wear resistance under the high thermal and mechanical loads of finishing hardened steels; this delivers longer intervals between index changes and reduces tooling costs per component. When compared to conventional carbide inserts for finishing, the CBN option maintains edge integrity for tougher materials, enabling a reliable, predictable process.

Geometry that stabilises cuts and improves surface quality

A 60° included angle and triangular plate form provide multiple usable cutting edges and favourable engagement for a variety of turning tasks. The 1.2 mm corner radius is optimised for finishing cuts, supporting improved surface integrity with minimal vibration. The insert’s 4.76 mm plate thickness and cylindrical hole support secure clamping, which reduces the risk of movement under load and contributes to repeatable part geometry and consistent surface finish during series production.

System compatibility and safe clamping for practical workshop use

Compatibility with toolholders depends on shape, clearance angle, tolerance class, clamping and thickness; this conforms to the ISO indexable insert system. The insert is supplied in the ISO size designation TNGA160412 and works with corresponding external holders, boring bars and shims that match the geometry and hole style. The cemented carbide substrate beneath the CBN layer ensures base stability and resistance to breakage during process disturbances, while the absence of a chipbreaker in this variant should be considered when matching insert selection to cutting conditions.

Practical advantages and recommended applications

This insert is particularly suited to final finishing and high-precision turning of hardened steels where edge life and surface quality are critical. Its CBN composition supports sustained cutting at moderate to high cutting speeds appropriate for abrasive, hardened materials, while the robust design reduces downtime for insert changes. For cast iron applications, confirm the specific version and chip control requirements before selection; matching the insert grade and holder rigidity to the machining setup secures the best outcome in cycle time and part quality.

FAQ

What materials is this insert suitable for?
The TNGA160412 BX360 insert is specified for machining hardened steels and, depending on the version, can also be used on cast iron; the CBN cutting phase provides high wear resistance for such applications.

How many cutting edges are available per insert?
As a triangular indexable plate, the TNGA160412 provides multiple cutting edges that can be indexed in sequence to extend tool life and reduce downtime.

Which holders are compatible with this insert?
Compatibility is determined by ISO geometry: holders and boring bars that accept the TNGA160412 form, thickness and cylindrical hole clamping will be compatible; check holder clearance and tolerance class before fitting.

Is a chipbreaker included with this grade?
This variant is supplied without a chipbreaker; chip control should therefore be managed via cutting parameters and holder stability or by selecting an alternative grade with an integrated chipbreaker if required.

What is the recommended use for the BX360 grade?
The BX360 CBN grade is intended for wear-intensive finishing of hardened workpieces, offering consistent edge life and quality in demanding turning operations.
