TPGW16T308 BX360 Tungaloy turning insert — CBN grade for hardened-steel finishing, 60° triangle

TPGW16T308 BX360 is an ISO-standard triangular insert engineered for precision turning of hardened components, offering a combination of wear resistance and dimensional stability for high‑performance finishing.

• CBN grade BX360 for hardened steels
• 60° triangular geometry for versatile turning
• Cylindrical hole with 40°–60° countersink
• 0.8 mm corner radius for accurate profiles

Consistent finish and long life for hardened machining

The BX360 grade, based on cubic boron nitride (CBN), is formulated specifically for the high abrasive wear encountered when machining hardened steels. Its dense CBN cutting layer provides superior thermal and chemical resistance compared with conventional carbide grades, which reduces flank wear and extends the interval between tool changes. With a corner radius of 0.8 mm and a 60° triangular geometry, the insert supports stable cutting edge engagement, enabling consistent surface quality and tight dimensional control during finishing passes.

Secure clamping and easy integration into ISO tool systems

Designed to the ISO turning insert standard, the triangular plate fits common external holders and boring bars when form, relief angle and thickness are matched. The insert features a cylindrical hole with a one‑sided countersink (40°–60°) that ensures reliable seating and repeatable orientation when fastened, while the plate thickness of 3.97 mm contributes to rigidity under finishing cuts. These mechanical particulars simplify tool changeovers and reduce setup variability, supporting higher process stability and reproducible cycle times.

Practical benefits for shop-floor productivity

Using a CBN insert like this one reduces rework and improves first‑pass accuracy in hard turning. The absence of a chipbreaker in this version supports smooth chip evacuation in many finishing conditions, while the 11° clearance angle helps to control cutting forces and minimise heat build-up at the cutting edge. Together, these features translate into lower unit machining costs for hard materials, fewer interruptions and improved component quality — advantages that are particularly valuable in high-mix or small-batch production environments.

FAQ

Which materials are suitable for this insert?
The insert is specified for the BX360 CBN grade and is intended primarily for hardened steels and, depending on the workpiece and grade adaptation, certain types of cast iron.

Is this insert compatible with standard ISO triangular holders?
Yes. The TPGW16T308 designation follows ISO geometry; compatibility depends on matching form, relief angle, tolerance class, fastening and plate thickness in the chosen holder.

What profile accuracy can be expected with a 0.8 mm corner radius?
A 0.8 mm corner radius supports accurate profile definition for finishing cuts and helps distribute cutting forces, improving edge life and consistency across series production.

Does this insert include a chipbreaker?
This version is supplied without a chipbreaker; it is intended for finishing operations where controlled chip formation and evacuation are achieved through process parameters and tool geometry.

How should the insert be fastened to ensure repeatable results?
Use the correct clamping set and screws matched to the holder and the insert’s cylindrical hole with countersink; proper seating and torque ensure repeatable orientation and optimal cutting performance.
