For setting the cutting tip (30) of a cutting tool (32) of a lathe, a tool-setting probe (10) has a stylus tip (18) for contacting the tool tip (30). The stylus tip (18) is generally cube-shaped. In addition to a conventional vertical datum surface (36) for setting the tool in the horizontal direction (arrow A), it has a 45 DEG sloping datum surface (38). The tool is touched in the direction of arrow A against both surfaces (36,38). The horizontal difference between the two contact positions is a measure of the height of the tool tip (30), enabling it to be set in the vertical direction.
