Abstract
A drill pipe mountable wellbore cleaning tool apparatus is of an improved configuration that enables attachment to a drill pipe joint having first and second connector end and a cylindrically shaped portion between the connector ends. The drill pipe joint with attached debris cleaning tool or tools is made part of a drill string. The apparatus includes a support sleeve mounted to the drill pipe joint between the connector ends. The support sleeve abuts without invading the integrity of the cylindrical portion. Centralizers are attached to the opposing ends of and are overlapping a portion of the support sleeve. The support sleeve carries one or more debris cleaning tools in between the centralizers to remove debris from a wellbore. At least one locking clamp is attached to the cylindrical portion next to a said centralizer, which prevents the support sleeve from moving longitudinally along the drill pipe joint.
