Description
den Enden Vies Rohrstückes und an beiden Enden jeder Bohrung 54 vorgesehen, um jegliches reibschlüssige Zusammenwirken möglichst klein zu halten. Die erzeugten Vibrations- oder Ratterbewegungen liegen im allgemeinen im hörbaren Bereich und können in ihrer Frequenz über den hörbaren Bereich hinausgehen. Daher müssen die Rohrstücke innerhalb der Bohrungen Gegenkräfte mit Frequenzen
lediglich ein Teil des Schaftes an irgendeiner Stelle bis zum Ende 58 der Abflachungen 12, die mit den Mitnehmerschlitzen 24 fluchtend ausgerichtet sind (Fig. 1), abgeschnitten wird. Vorzugsweise ist
der Teil des Schaftes IQ, in dem die Bohrungen 54 ausgebildet
sind, kurzer als 25 % der Gesamtlänge des Halters. Die hervorragende Festigkeit der beschriebenen Schneidstange ermöglicht
die Verwendung eines weicheres Stahls mit einer geringeren Eigenfrequenz. Eine derartig geringere Frequenz wird ihrerseits wirk-
Bohrungen 54 ist, haben sich beim Feinbohren und Rohrstücke 56
mit einem um 0,125 mm kleineren Durchmesser als der der Bohrungen 54 haben sich zum Grobbohren mit der gleichen Schneidstange
als günstig erwiesen. Für beide Bohrarten sind Endspalte von
0,05 mm geeignet.
