TPGA 110204 BX360 – Turning indexable insert (TPGA110204) by Tungaloy

TPGA 110204 BX360 is an ISO‑standard triangular turning insert engineered for high‑hardness finishing and reliable wear resistance in turning applications.

• CBN grade BX360 for hardened steels
• Triangular ISO form, 11 mm inscribed circle
• 0.4 mm corner radius for fine finishing
• Cylindrical hole for secure clamping

High‑precision finishing on hardened materials

The combination of cubic boron nitride (CBN) in the BX360 grade and the triangular geometry delivers consistently high surface quality when turning hardened steels. CBN is a superhard abrasive material optimised for machining steels at elevated hardness; it maintains edge stability under thermal and mechanical stress, which reduces rework and increases first‑pass yield. This makes the insert particularly suited to final‑pass operations where dimensional accuracy and surface finish are decisive.

Predictable fit and clamping in ISO systems

Manufactured to ISO dimensions, the insert fits standard triangular holders when the form, clearance angle and tolerance class match. The cylindrical hole ensures secure seating and repeatable indexation, while the 11° relief angle supports favourable cutting geometry for many holder designs. Clear specification of the insert geometry simplifies changeovers and reduces setup time, supporting stable production workflows.

Durable edge life for consistent throughput

The specification highlights durability: a carbide substrate with a CBN cutting phase in the BX360 grade provides resistance to abrasive wear typical of hard turning. The 0.4 mm corner radius balances edge strength with the ability to achieve fine surface finishes; this radius reduces the risk of edge chipping during interrupted cuts and contributes to longer tool life, lowering tool consumption and machine downtime.

Practical application and selection guidance

For optimal results, pair the insert with a holder matched to the TPGA form and ensure correct clamping torque. Select the BX360 variant when the workpiece material is hardened steel or when demanding finish quality is required; if machining cast iron is indicated by the process, verify the specific BX360 variant suitability. When in doubt about feed, speed or insert orientation for a particular setup, Metav Werkzeuge’s technical team can provide application guidance tailored to the machining task.

FAQ

What materials is this insert intended for?
The TPGA 110204 BX360 insert is designed primarily for hardened steels; the BX360 CBN grade also offers variants suitable for certain cast‑iron applications depending on the execution.

How is the insert secured in the holder?
The insert features a cylindrical hole for mechanical clamping; correct seating in a matching triangular ISO holder and proper clamping torque ensure stable indexing and repeatable performance.

What surface finish can be expected with a 0.4 mm corner radius?
A 0.4 mm corner radius provides a balance between edge strength and finishing capability, enabling fine surface finishes in final passes while maintaining robust edge life.

Is the insert suitable for interrupted cuts or grooving operations?
The carbide substrate with a CBN cutting phase and the 0.4 mm corner radius offer improved resistance to chipping, making the insert more tolerant in interrupted cutting; suitability should be confirmed against the specific cutting conditions.

Which holders are compatible with this ISO insert?
Compatibility depends on matching the ISO TPGA form, 11° relief angle, tolerance class and size; use holders specified for triangular TPGA inserts and ensure the clamping system accepts a cylindrical‑hole style insert.
