Conical drill bit

The fischer conical drill bit PBB guarantees the secure and approval-compliant fixing of heavy loads in aerated concrete with the fischer injection system. Drill hole and undercut are created with the conical drill bit in one working step. The cone-shaped drill hole enables maximum load-bearing capacity in aerated concrete thanks to the interlock. The drill hole is filled by the centring sleeve PBZ, which is placed on the drill hole. The fischer threaded rod FIS A or the fischer internal threaded rod FIS E are inserted with a slight rotating movement. The system components enable the secure fixing in aerated concrete of railings, cantilevers and lightweight steel constructions indoors and outside.
