  Reibahle mit schraubenförmigen Schneidrippen von hoher Steigung. 



   Die Erfindung bezieht sich auf eine Reibahle mit   schraubenförmigen   Schneidrippen von hoher Steigung, bei welcher die Schneidrippen vorteilhaft ungleiche Abstände voneinander haben. Gemäss der Erfindung sind in die Sehneidrippen Ausfräsungen eingearbeitet, vorteilhaft hinterarbeitet, deren Steigung der Steigung der Schneidrippen entgegengesetzt ist. Die neue Reibahle bietet den Vorteil, dass sie in gleicher Weise als Maschinen-und als Handreibahle verwendet werden kann. Sie ermöglicht bei wenig Kraftbedarf eine bedeutend grössere Spanabnahme bei bedeutend kürzerer Arbeitszeit gegenüber Reibahlen mit gewöhnlicher Verzahnung.

   Die quer zu den   Schneidrippen   verlaufenden Ausfräsungen bringen dabei den grossen Vorteil mit sich, dass der sonst starke axiale Druck in der Richtung des die Reibahle fassenden Futters sehr vermindert wird. 



   Da die Schneidrippen gewöhnlich mit Linksgewinde verlaufen, so verlaufen die Ausfräsungen also mit Rechtsgewinde. 



   Die Zeichnung veranschaulicht die Erfindung beispielsweise. Die Reibahle b hat Zähne, welche

   Es kann nun kein Festklemmen der Reibahle infolge der linksgängigen Schneidzähne auftreten, und der zum Vorschieben der Reibahle erforderliche Axialdruck ist verhältnismässig gering.

  Reamer with helical cutting ribs of high pitch.



   The invention relates to a reamer with helical cutting ribs of high pitch, in which the cutting ribs are advantageously unequal distances from one another. According to the invention, cutouts are machined into the cutting ribs, advantageously undercut, the slope of which is opposite to the slope of the cutting ribs. The new reamer has the advantage that it can be used in the same way as a machine and hand reamer. With little power requirement, it enables a significantly larger chip removal with significantly shorter working time compared to reamers with conventional teeth.

   The cutouts running transversely to the cutting ribs have the great advantage that the otherwise strong axial pressure in the direction of the chuck gripping the reamer is greatly reduced.



   Since the cutting ribs usually run with a left-hand thread, the millings run with a right-hand thread.



   The drawing illustrates the invention by way of example. The reamer b has teeth, which
 EMI1.1
 



   The reamer cannot jam as a result of the left-hand cutting teeth, and the axial pressure required to advance the reamer is relatively low.
