TPGA090204 BX360 ISO triangular turning insert, CBN for hardened steel (Tungaloy)

A TPGA090204 BX360 insert for ISO‑compliant external and internal turning, designed for high‑hardness finishing and stable chip control in demanding production environments.

• CBN grade BX360 for hardened steels
• ISO triangular form, 60° cutting angle
• Cylindrical hole for secure clamping
• 0.4 mm nose radius, 2.38 mm thickness

Precise finishing for hardened components with measurable benefits

The triangular indexable insert offers a defined 60° orientation and a small 0.4 mm nose radius, delivering controlled engagement and consistent profile accuracy in finishing passes. The use of cubic boron nitride (CBN) in the BX360 grade provides superior abrasion resistance compared with conventional carbide grades, which translates into fewer tool changes and reduced downtime. Where repeated dimensional accuracy and surface integrity matter, the hardened‑material capability of this insert supports high‑quality end results with predictable tool life.

Secure seating and compatibility to reduce set‑up variability

Engineered to ISO dimensions, the insert fits standard external holders and boring bars when form, clearance angle and thickness are matched. The cylindrical hole in the centre allows positive clamping and repeatable positioning, limiting micro‑movement during interrupted cuts. Presented as a component of a system — insert, seat/adapter and fastening hardware — the standardised geometry simplifies inventory management and reduces set‑up effort across multiple machines.

Productivity through a wear‑resistant CBN grade

The BX360 cutting material is optimised for high‑hardness applications and abrasive finishing. CBN provides stable edge retention at elevated temperatures and maintains surface finish over extended cycles, which improves process economics by extending service intervals. For shops turning hardened steels or certain cast irons, the CBN grade enables higher cutting speeds in finishing operations while preserving dimensional stability and surface quality.

Selection guidance and practical application notes

For external and internal turning applications, select the grade and chipbreaker suited to the workpiece material and the intended operation; this insert is supplied without a chipbreaker, making it suitable for stable finishing cuts where chip form is controlled by cutting parameters and holder geometry. The plate thickness of 2.38 mm and ISO size 09 suit light to moderate radial engagements in finishing programmes. When machining hardened components, pair the insert with rigid clamping, minimal tool overhang and stable feed to fully exploit the grade’s wear resistance.

FAQ

What materials is this insert designed for?
The TPGA090204 BX360 insert uses a CBN cutting material and is designed primarily for hardened steels and, depending on the specific version, certain cast irons; it is optimised for wear‑intensive finishing.

How does the BX360 grade affect tool life?
The BX360 CBN grade offers superior abrasion resistance compared with conventional carbide, resulting in longer edge retention and extended service intervals in high‑hardness finishing operations.

Is the insert compatible with standard ISO holders?
Yes. The TPGA090204 follows ISO geometry; compatibility depends on matching form, clearance angle, thickness and fastening method to the holder or boring bar.

Can this insert be used for roughing operations?
This insert is primarily intended for finishing on hardened materials; for heavy roughing, a different geometry and possibly a different grade would be recommended to handle larger depths of cut.

What does the absence of a chipbreaker mean in practice?
Supplied without a chipbreaker, the insert requires chip control to be managed via cutting parameters and holder geometry, which is common for precise finishing operations where a clean surface and minimal distortion are priorities.
