TPGA 160304 BX360 turning insert by Tungaloy — CBN grade for hardened steels

The TPGA160304 BX360 turning insert is an ISO-standard triangular insert designed for precision external and internal turning of hardened steels and, depending on specification, cast iron.

• CBN grade BX360 for hardened steels
• ISO TPGA160304 triangular insert form
• 0.4 mm corner radius for precision finishes
• Cylindrical hole for secure clamping

High-wear performance for demanding finishing operations

The TPGA160304 BX360 is manufactured to deliver high abrasion resistance through its CBN cutting material and the BX360 grade. This combination is intended for end finishing and high-hardness turning where tool life and surface quality are critical. By using cubic boron nitride as the cutting medium, the insert offers significantly greater resistance to flank wear compared with conventional carbide tools when machining hardened steels. The result is more consistent part geometry and reduced need for frequent tool changes, supporting uninterrupted production and predictable downtime planning.

Reliable fit in ISO systems for straightforward tool interchangeability

Compatibility with the toolholder is defined by the insert geometry, ISO-standard designation, relief angle and fastening method. The triangular triangular form and the cylindrical hole ensure consistent seating and repeatable location in standard TPGA-style holders. Because tolerance class, size and thickness are standardised, the insert can be integrated into existing tool systems without modifying fixtures, which simplifies inventory management and reduces setup time for changeovers.

Precise finishing and surface integrity from optimised edge form

The 0.4 mm corner radius supports smooth material flow at the cutting edge and contributes to a fine surface finish in finishing cuts. For high-hardness materials the CBN edge maintains dimensional stability under thermal and mechanical stress, producing fewer vibrations and a reduced tendency for built-up edge. In practice this means fewer rework steps and an improved first-pass yield when finishing bearing seats, shafts or other components requiring tight tolerances and consistent surface quality.

Practical considerations for secure clamping and process reliability

The insert is supplied in a form that requires a compatible outer holder or boring bar, a suitable clamping pad or clamp set, and the correct fastening screw. Selection of the holder and stability of the assembly are decisive for the achievable feed rates and surface finish; a rigid setup extends insert life and enables higher metal removal rates for roughing-to-finishing sequences. If additional machining parameters or holder recommendations are needed, documented cutting data can be provided to align the insert with machining centre capability and the chosen process window.

FAQ

What materials is this insert best suited for?
The TPGA160304 BX360 insert is optimised for hardened steels and, in specific variants, for cast iron; the CBN cutting material ensures strong wear resistance on high-hardness workpieces.

How does the BX360 grade affect tool life?
BX360 is a CBN grade designed for wear-intensive finishing; the BX360 formulation prolongs tool life in comparison with conventional grades when machining hard materials.

Is the insert compatible with standard TPGA holders?
Yes, the ISO designation and the cylindrical hole permit seating in standard TPGA holders, but compatibility also depends on holder form, tolerance class and clamping method.

What surface finish can be expected with a 0.4 mm corner radius?
A 0.4 mm radius supports fine finishing passes and contributes to stable cutting conditions that typically yield improved surface integrity and reduced need for rework.

Are replacement screws and clamping pads required for installation?
A complete system includes the insert, a matching holder or boring bar, the appropriate clamping pad or clamp kit, and the correct replacement screws to ensure secure fastening and repeatable indexing.
