Drill bush DIN 179 form A, bore 17.5 mm, length 28 mm, outside dia 26 mm, hardened steel
During drilling in the jig this bush takes over the guidance of the 17.5 mm tool. The overall length of 28 mm sets the bearing surface of the drill in the medium version, and the bore matches form A of DIN 179.
Benefits
- Guide bore of 17.5 mm to DIN 179 for the matching tool
- Bore rounded on one side to form A, with a fixed fitting direction in the jig
- Outside diameter of 26 mm as a ground seat in the drill plate
- Guide length of about 1.6 drill diameters at 28 mm of length
- Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground
