Replacement for the long-running Zara-series. The NCB-20 bores cylinder blocks for cars, LCVs, tractors and compressor bodies with sub-5-micron roundness.
Cast-iron column and base, ribbed for torsional rigidity. Tapered roller-bearing spindle gives virtually zero radial play; the square-section boring bar accepts a quick-change tool holder.
