Drill bush DIN 179 form A, bore 2.7 mm, length 8 mm, outside dia 6 mm, case-hardened steel

This drill bush guides tools of 2.7 mm diameter and keeps the drill axis in position over the full length of 8 mm. The material is special case-hardening steel, hardened to 740 ± 80 HV 10, which keeps wear of the guide low over many workpieces.
