A tool for cutting tubular members comprising:

• a tool housing;
• an input shaft received in a rear end portion of the tool housing, the input shaft configured to be driven in rotation by a motor,
• a transmission received in the tool housing and including a rotatable input member configured to be driven by the input shaft and a rotatable output member configured to be driven by the rotatable input member;
• and
• a cutting head received in a front end portion of the tool housing, the cutting head including a head housing with a central opening configured to receive a tubular member in the central opening and to be rotatably driven by the rotatable output member of the transmission, the cutting head including a cutting blade configured to protrude at least partially into the central opening, a roller configured to protrude at least partially into the central opening, and a releasable lock assembly,
• wherein the cutting blade and the roller are biased inward toward a center of the central opening, movable outward from the central opening to accommodate multiple sizes of tubular members in the central opening, and lockable by the releasable lock assembly in a desired position to accommodate a tubular member of a desired size, the releasable lock assembly configured to automatically actuate by insertion of the tubular member independent of operation of the motor, and
• wherein, in a locked position, the roller and the cutting blade engage the tubular member so that the cutting blade cuts the tubular member as the cutting head rotates about the tubular member.
