Drill head

The firing relates to a drill head with a plurality from adjacent drilling spindles. Bohrkopfa this Kind that have an ejriisaere number of adjacent ones Own spindles, in which mostly drills from relative hoses kleina ^ Darohinossör are a ^ esptuint, become tsar Core division of u; ezittlzwecken ilienendon sheets used, which have a very large number of small holes. Under certain circumstances, the number of these holes can be in the hundreds of thousands or even in the millions. With such drill bits it happens that one of the tools breaks off or is pushed back into the drill chuck. The operator, however, is far from the large number of ears hardly able to detect such disturbances immediately after Occurrence. Rather, such errors usually only appear after a long period of time on the irregularities determined «which the finished workpiece has ·
