TPGW 090202 BX360 Tungaloy turning insert

The TPGW 090202 BX360 is an ISO‑standard triangular indexable insert designed for precision external and internal turning of hardened steels and similar high‑hardness materials.

• CBN grade BX360 for high wear resistance
• ISO TPGW090202 triangular geometry
• 11° clearance angle for stable cutting
• 0.2 mm corner radius for fine surface quality

Longer runtimes through CBN technology

The BX360 grade uses CBN (cubic boron nitride) to deliver markedly higher wear resistance compared with conventional carbide grades when machining hardened steels. This results in a more stable cutting edge during long finishing passes and fewer indexings per workpiece, which improves throughput and reduces unplanned tool changes. The material behaviour of CBN at elevated temperatures enables predictable tool life in wear‑intensive tasks, making the insert especially suited to demanding end‑machining operations where surface integrity and dimensional stability matter.

Predictable mounting and repeatable results

The insert conforms to ISO geometry and its triangular form with 60° included angle ensures a standardised interface to compatible holders. Compatibility to a particular clamping system is determined by form, 11° clearance angle, tolerance class, fastening method, size and thickness, so selecting the correct external holder or boring bar is essential for repeatable results. The presence of a cylindrical hole with a single‑side countersink (40°–60°) provides secure seating under a clamp or screw, delivering consistent cutting conditions and reliable batch‑to‑batch performance.

Practical handling and application guidance

The plate is supplied without a chipbreaker, offering a smooth cutting edge for fine finishing; the 0.2 mm corner radius and 2.38 mm thickness support precise surface generation and controlled cutting forces. Typical applications include external and internal turning of hardened steels, and certain executions of this grade may be suitable for cast iron depending on the workpiece and process parameters. For installation, use the correct underlay, clamp set and replacement screws as part of the system assembly; this ensures the mechanical seating and torque are correct and helps to maintain repeatable tool life and surface quality.

FAQ

Is this insert suitable for hardened steels?
The TPGW 090202 BX360 insert is specifically designed for hardened steels, where the CBN BX360 grade provides superior wear resistance for finishing and light roughing applications.

Can the insert be used for internal turning as well as external turning?
Yes, the TPGW 090202 BX360 is applicable to both external and internal turning when paired with the correct holder and clamping parts, enabling stable cutting conditions for internal bores and faces.

Does this insert include a chipbreaker?
No, the supplied TPGW 090202 BX360 insert comes without a chipbreaker, offering a polished cutting edge for fine surface finishes; users should select cutting parameters and an appropriate holder to manage chip evacuation.

What does the plate hole specification mean for mounting?
The insert features a cylindrical hole with a single‑side countersink (40°–60°), providing positive seating under a screw or clamp and ensuring repeatable location when installed in a compatible ISO holder.

How does the 0.2 mm corner radius influence surface finish?
A 0.2 mm corner radius balances edge strength and surface generation, allowing fine finishes on hardened components while limiting cutting forces; it is suitable for final passes where dimensional accuracy and surface quality are priorities.
