US 2026/0266137 A1 · DRILLING ASSEMBLY SYSTEMS AND METHODS

Abstract

An apparatus can include a drilling tool having a proximate and distal end. The drilling tool can include an internal threaded section proximal the distal end of the drilling tool, a gripper apparatus affixed to an exterior surface of a portion of the drilling tool. The gripper apparatus can be configured to selectively extend and increase an outer diameter of the portion of the drilling tool and to selectively retract and decrease the outer diameter of the portion of the drilling tool. The drilling tool can include a cylindrical sleeve having external threads extending from at least a portion of an outer surface of the cylindrical sleeve, the cylindrical sleeve configured to travel inside the drilling tool and have the external threads engage with the internal threaded section. The drilling tool can include an inner and outer bearing sections. Methods of using the tool for drilling are also disclosed.

Dependent claims

A drilling tool, comprising:

a drilling tool having a proximal end and a distal end;
a gripper section having an external wall, an engagement mechanism having one or more gripper feet, an extended orientation and a retracted orientation, wherein in the extended orientation an outer diameter of the gripper section comprises an outer diameter greater than an outer diameter of the external wall of the drilling tool;
and
a sleeve having a complementary engagement track extending from at least a portion of an outer surface of the sleeve, the sleeve having a first orientation, and a linearly translated orientation wherein the complementary engagement track engages with the engagement mechanism when the gripper section is in the extended orientation.
