Cutting tool

Abstract

A cutting tool ( 10 ) for cutting a tubular. The cutting tool ( 10 ) comprises a cutting element ( 18 ) which defines a cutting profile, a first drive mechanism ( 20 ), which is operable to rotate the cutting element ( 18 ); and a second drive mechanism ( 22 ), which is operable to control the displacement of the cutting element ( 18 ) with respect to a surface of the tubular that is to be cut. The first and second drive mechanisms ( 20, 22 ) are arranged such that they are independently powered.
