Drill bush DIN 179 form B, bore 3.8 mm, length 12 mm, outside dia 7 mm, case-hardened steel
This drill bush guides tools of 3.8 mm diameter and keeps the drill axis in position over the full length of 12 mm. Form B to DIN 179 means that the bore is rounded on both sides, while the outside diameter of 7 mm determines the fit in the fixture.
