Cone drill for undercut drill holes in aerated concrete.
The fischer cone drill PBB is a special driller for creating a fixing in aerated concrete with a conical drill hole. The cone drill allows for the drill hole and the undercut to be made in one work step by pivoting the drill. This is then filled with fischer injection mortar FIS V and the anchor rod FIS A or the internal threaded anchor FIS E is set by lightly rotating it.
