Abstract

A tubing cutting tool (1) comprises a fluid powered rotary motor having a body (5) and a rotary output member (9); first fluid pressure responsive means (7) for locking the body to the tubing to be cut when the pressure of the motor operating fluid exceeds a first predetermined value; a rotary cutter (10) connected to the rotary output member of the motor for rotation therewith, the rotary cutter having at least one cutting element (11) which is normally located at a first radial distance from the longitudinal axis of the tool; and second fluid pressure responsive means (16) operable in response to the pressure of the motor operating fluid exceeding a second predetermined value to move the or each cutting element radially outwardly from its normal position to engage the tubing to be cut. <IMAGE>
