Reamer elements for use with roller reamers and other types of reamer apparatuses, methods for forming such reamer elements, and methods for performing drilling operations using such reamer elements are disclosed. The reamer element includes a body formed from a matrix of tungsten carbide and at least one binding metal, and can include a tube disposed therethrough. In use, the body resists compressive forces, while the tube resists tensile forces, thereby preventing deformation of the reamer element. The matrix material of the body provides increased wear resistance, decreased magnetic interference, decreased yield, and increased weight on a drill bit when compared to conventional steel components.
