Drill bush DIN 179 form A, bore 45.5 mm, length 30 mm, outside dia 62 mm, case-hardened steel

With an outside diameter of 62 mm the bush is seated in the bore of the jig plate and guides the drill of 45.5 mm nominal diameter. The material is special case-hardening steel, hardened to 740 ± 80 HV 10, which keeps wear of the guide low over many workpieces.
