Drill bush DIN 179 form A, bore 10.9 mm, length 12 mm, outside dia 18 mm, case-hardened steel

With an outside diameter of 18 mm the bush is seated in the bore of the jig plate and guides the drill of 10.9 mm nominal diameter. Form A to DIN 179 means that the bore is rounded on one side, while the outside diameter of 18 mm determines the fit in the fixture.
