Title
(EN) DRILL BIT FOR BORING EARTH AND OTHER HARD MATERIALS
(FR) TRÉPAN POUR FORER LA TERRE ET D'AUTRES MATÉRIAUX DURS
Abstract
(EN)
A drill bit assembly for drilling a hole through earth, the drill bit comprising: a bit body extending between a first end and a second end along a longitudinal axis of the bit body with a connecting arrangement positioned at the first end of the bit body for coupling the bit body to a rotating shaft for providing rotational torque to the bit body; a cutting head including a leading tip portion for cutting into earth and a trailing receiving portion for receiving the second end of the bit body in an internal cavity defined by the receiving portion to allow the cutting head to be removably coupled to the second end of the bit body; a retaining arrangement to retain the second end of the bit body in the receiving portion of the cutting tip.
(FR)
La présente invention concerne un ensemble à trépan pour percer un trou à travers la terre, le trépan comprenant : un corps de trépan qui s'étend entre une première extrémité et une seconde extrémité le long d'un axe longitudinal du corps de trépan avec un agencement de raccordement positionné au niveau de la première extrémité du corps de trépan pour coupler le corps de trépan à un arbre rotatif pour fournir un couple de rotation au corps de trépan; une tête de coupe qui comprend une partie d'embout avant pour couper dans la terre et une partie de réception arrière pour recevoir la seconde extrémité du corps de trépan dans une cavité interne définie par la partie de réception pour permettre à la tête de coupe d'être couplée de manière amovible à la seconde extrémité du corps de trépan; un agencement de retenue pour retenir la seconde extrémité du corps de trépan dans la partie de réception de l'embout de coupe.
