UNDERREAMER FOR INCREASING A BORE DIAMETER
An underreamer for increasing the diameter of a bore. The underreamer includes a substantially cylindrical body having an axial bore therein. A mandrel may extend axially through the axial bore. One or more cutter blocks are movably coupled to the body. A ratio of a height of the cutter block to a d...

| description | An underreamer for increasing the diameter of a bore. The underreamer includes a substantially cylindrical body having an axial bore therein. A mandrel may extend axially through the axial bore. One or more cutter blocks are movably coupled to the body. A ratio of a height of the cutter block to a diameter of the body is between about 0.35:1 and about 0.50:1.
La présente invention concerne un élargisseur permettant d'agrandir le diamètre d'un alésage. L'élargisseur comprend un corps sensiblement cylindrique dans lequel se trouve un alésage axial. Un mandrin peut s'étendre de façon axiale à travers l'alésage axial. Un ou plusieurs blocs coupants sont accouplés mobiles au corps. Un rapport d'une hauteur du bloc coupant à un diamètre du corps est compris entre environ 0,35:1 et environ 0,50:1. |
