Description

  •
    den außenliegenden zylindrischen Bereichen des Schaftes 12. Daher kann*eine etwas größere Tiefe der Nuten 62-als die oben erwähnte Grenze der halben Wand tä:rke des ringförmigen . Sehneideinsatzes kein vollständiges Durchbrechen oder Durchreißen der Nuten zur Folge haben,, bevor nicht etwa der.Schaftmantel'bis zu einem kritischen Ausmaß ausgearbeitet, d.@ h: dünn geworden ist. Es wird angenommen, daß die optimale Tiefe einer Nut bei 55 % der Wandstärke des ring= förmigen Schleifeinsatzes liegt, wobei s4eh auf (rund des oben beschriebenen Ausgleichs der Reibungskräfte eine größtmögliche Lebensdauer des Kernbohrers ergibt. Für eine leichtere Herstellung eines zufriedenstellend arbeitenden 'lange brauchbaren Kernbohrers genügtes, wenn die Tiefe der Nuten 60 und 62 über ihre ganze Länge gleich und gieiah . der halben Wandstärke des' ringförmigen Schneideinsa@tzea gemacht wixd. -
