Drill bush DIN 179 form A, bore 7.4 mm, length 16 mm, outside dia 12 mm, case-hardened steel
The material, hardened to 740 ± 80 HV 10, keeps the 7.4 mm guide bore accurate even after many drilling cycles. The outside diameter measures 12 mm. The 12 mm seat and the 7.4 mm bore are ground, so the bush can be pressed into the fixture without any rework.
