A milling cutter has an axis, a head and a body. The head has multiple blades extending transversely out from the axis and each blade has a cutting surface parallel to the axis. The body is formed integrally on and extends from the head, has a top end and multiple side edges and is tapered from the head to the top end. The milling cutter is able to define recesses or cutouts in a workpiece without causing a rapid rise in temperature of the milling cutter because the tapered body never contacts the workpiece during the cutting process.
