Drill bush DIN 179 form A, bore 3.3 mm, length 12 mm, outside dia 6 mm, hardened steel
This drill bush guides tools of 3.3 mm diameter and keeps the drilling axis in position over the full length of 12 mm. The bore follows form A of DIN 179 and is therefore rounded on one side.
Benefits
- Guide bore of 3.3 mm to DIN 179 for the matching tool
- Outside diameter of 6 mm as a ground seat in the drill plate
- Bore rounded on one side to form A, with a fixed fitting direction in the jig
- Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground
