Abstract
Official abstract text for this publication.
Underground drilling operation often requires connecting a drill tool (e.g., drill bit, backreamer, etc.) to a drill string. It is desirable to connect the drill tools to a drill string in a manner that facilitates quick and easy assembly and disassembly. Low torque coupling, commonly referred to as “torque-less” connection, can provide such functionality. The useful life and strength of such connections can be improved upon. The present disclosure provides a low torque coupling with improved strength and durability.
First claim
Opening claim text (preview).
The invention claimed is: 1. A threaded interface for using in connecting a removable down hole tool to a drill string, the threaded interface comprising: a down hole end portion configured to interface with the removable down hole tool assembly; an up hole end portion opposed to the down hole end portion, the up hole end portion being configured to interface with the drill string as part of a low torque coupling, the up hole end portion including: a non-threaded non-tapered fi…
