Abstract

A cutting insert (10) for use in a wellbore milling tool comprising a base which can be mounted on a surface of said wellbore milling tool and a plurality of cutting surfaces (25, 26, 27) which are separated from one another 13y linear boundaries (16, 18). This construction helps facilitate the formation of relatively narrow chips.
