Reverse countersink system

Design: Reversal protection lock prevents disjointing of the countersink when machining vertically or with machines with engine brakes. Guide in the workpiece bore ensures reliable machi- MK shank ning of difficult contours. Wide driving surface enables transmission of large torques. From shank size MK3 the holder can be secured via a cross-wedge slot.
