Abstract: A remote cutting tool for insertion into an underground sewage pipe for trimming branch line stub ends that extend into the sewage pipe. The cutting tool comprises a sled adapted to be drawn through the interior of the pipe by cables attached thereto. A cylindrical cutting bit is driven by a hydraulic motor, the motor and bit being retained on the sled through a hydraulic jack ram. The jack ram facilitates the axial movement of the motor and bit with respect to the sled as required to effect branch stub cutting. Expandable pneumatic sleeves are provided on the sled which, when inflated, lock the sled in fixed orientation in the pipe prior to each cutting operation. A guide member is positioned over the pneumatic sleeve adjacent the point of intended cutting to deflect the sleeve in the opposed direction and to align the cutting bit in close proximity to the sewer pipe wall at the point of stub pipe entry.
