Abstract

A sample removing tool comprises two partly spherical blades which are rotatably mounted on a carrier member about parallel axes. The cutting edges of the blades face each other and a portion of the cutting edges are arranged to lie in a nominal circle. The carrier member is rotatably mounted on a support member about an axis, the axis is perpendicular to a plane containing the nominal circle and passes through the center of the nominal circle. The axes of the blades are inclined to the axis of rotation of the carrier member. The blades are rotated about their axes and the carrier member is rotated about its axis such that the cutting edges of the blades move along the circumference of the nominal circle to cut a sample from a surface of a component arranged perpendicular to and intersecting the nominal circle.
