Collar drill bushing DIN 172 form B, bore 9 mm, length 12 mm, collar 18 mm, hardened steel

The collar drill bushing with a 9 mm bore comes in the short series at 12 mm. Its case-hardening steel at 740 ± 80 HV 10 withstands contact with the cutting edge over large batches, and the 18 mm collar fixes its position.
