A cutting element includes a front face and leading face extending between a first and second sides. A leading cutting edge is located at an intersection of the front face and the leading face, and an undulating back-up cutting edge is formed in the front face and extends from the first side to the second side, and defines a leading surface and a trailing surface. A method includes cutting with a tool having a blade coupled to a tool body, and a cutting element coupled to a forward surface of the blade. The cutting element has a leading cutting edge formed at an intersection of front and leading faces, and an undulating back-up cutting edge formed in the front face and defining leading and trailing surfaces. The leading cutting edge of the cutting element contacts and cuts a work piece.

Milling cutter having undulating chip breaker

A system and method for facilitating the drilling of a deviated borehole. The system and method employ a flexible conveyance. A hydraulic actuation assembly is coupled to the flexible conveyance and a whipstock is releasably coupled to the hydraulic actuation assembly. The whipstock and hydraulic actuation assembly are conveyed downhole in the wellbore. The hydraulic actuation assembly provides a hydraulic fluid under pressure to anchor the whipstock.

System and method to facilitate the drilling of a deviated borehole

A vibrating downhole tool comprising a housing, an inner mandrel disposed within the housing and configured to receive a drilling fluid, a mass coupled to the inner mandrel, and a plurality of turbine blades configured to receive the drilling fluid and to rotate the inner mandrel and the mass, thereby causing the vibrating downhole tool to vibrate.
