Patent ID: 7422399

Claim:
A debeading tool for debeading a joint in butt-welded plastic pipe, comprising: a torque tube for insertion into a length of cylindrical pipe; means for rotating the torque tube about an axis that is substantially coaxial with the pipe; a clamp positioned along the torque tube to fix the tool in a debeading position lengthwise in the pipe; a work head including a frame sized to fit within the pipe, coupled to a distal end of the torque tube; a locating gauge mounted on a distal end of the frame for contacting a weld bead when the tool is pushed longitudinally into the pipe; and a rotary cutting motor mounted on the frame for movement transversely of the torque tube axis between an insertion/removal position and a cutting position and having an output shaft oriented in the cutting position at a predetermined angle relative to the torque tube axis; and a rotary multifluted cutter mounted on the output shaft in longitudinal alignment with the locating gauge; the cutter having a plurality of cutting flutes oriented at an angle to the motor output shaft such that the cutting flutes are substantially parallel to an interior wall of the pipe when the tool is in the cutting position for cutting the weld bead.
