Kyocera TNGA160404S01525 A66N

• Insert designation: TNGA160404S01525 A66N.
  
  Shape and geometry: 60° triangle (TN series) negative insert type.

• Size/IC code: 1604 series (i.e., approx. 9.525 mm inscribed circle) with a 0.4 mm corner radius.

• Chipbreaker: S01525 – designed for excellent chip control and consistent turning performance

• Grade: A66N – a high-performance ceramic/ceramic-type insert material in the Kyocera system

• Material/coating: From the Kyocera “Turning Indexable Inserts” range, A66N falls under advanced ceramic grade/insert material category. 

• Application: Optimised for turning (external & internal) work-pieces of steel, cast iron, and high-hardness materials (with the right conditions).

• Longer tool life – The A66N grade and robust geometry mean less frequent insert changes and more stable work cycles, which translates into lower cost per component.

• Better surface finish – Thanks to the triangular geometry and fine chipbreaker, machining interruptions and chatter are minimised, producing smoother finished parts.

• High wear resistance – The advanced material and precision edge preparation cut down flank wear and edge breakdown, meaning fewer rejects and more uptime.

• Less downtime – With consistent performance and fewer insert changes in typical operations, your machining cell spends more time producing and less time resetting.

This insert is ideal for heavy-duty turning and internal/external operations in:

• Automotive component manufacturing

• Aerospace structural and engine parts

• Die & mold industry (where high precision and surface finish matter)

• General engineering & heavy machinery fabrication
