Abstract
A cutting element comprises a cylindrical substrate, a table bonded to the substrate, a working surface on the top of the table, and a plurality of dimples on the working surface. The table is made of super-abrasive material. The super-abrasive material can be PCD. Surface patterns of the table can reduce contact friction between the rock and the cutting element. Therefore, heat on the table can be reduced and thermal damage to the table is decreased. This results in improved cutting element service life.
