Bigger sibling of the NCB-20. Heavier column, larger table and a 350 mm bore envelope — for heavy truck, marine and industrial diesel blocks.
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.
