Abstract
A cutting element assembly includes a cutting element and a sleeve having a cutter-receiving aperture configured to receive at least a portion of the cutting element within the cutter-receiving aperture. The cutting element assembly may also include a retention element rotatably coupling the cutting element to the sleeve and a biasing member disposed between the cutting element and the sleeve. The biasing member may be configured to bias the cutting element relative to the sleeve. A method of forming a downhole tool includes forming a bit body including at least one blade, securing at least one sleeve to the blade, disposing at least one biasing member within the cutter-receiving aperture, and inserting a cutting element into the cutter-receiving aperture of the at least one sleeve, such that the at least one biasing member is disposed between the at least one sleeve and the cutting element.
