Abstract
A slip assembly for a downhole tool, such as a composite plug, has a slip body and at least one insert. The slip body has an incline at one end that interfaces with an inclined surface of a cone. As this occurs, the slip body is pushed away from the tool's mandrel against a surrounding casing wall. The insert is disposed in the slip body with the axis of the insert angled away from the cone. In particular, the insert's axis is preferably angled normal to the slip body's incline and the inclined surface of the cone.
