A cutting tool (1) comprising a body (2) configured for attachment to a tool holder and defining a cutting zone having at least one cutting edge (6), wherein the body includes at least one first passage (12) for delivering a supply of oil, and at least one second passage (7) for delivering a supply of compressed gas, the first and second passages being adapted to be fluidly connected to respective oil and compressed gas supplies (13, 8) external to the cutting tool, and wherein the first passage and the second passage meet at a mixing chamber (15) adjacent an exit (11) in the cutting zone such that the oil and compressed gas, in use, form an atomised oil mist which is ejected from the exit for minimum quantity lubrication (MQL) or near-dry machining (NDM) operations. The cutting tool may be an end mill. Also, a machine tool with the cutting tool, and a method of machining, whereby oil and compressed gas are supplied separately to the cutting tool where they are mixed adjacent to an exit to the cutting zone before being ejected from said exit.
