Abstract
An internal pipe cutter of simplified construction allows easy conversion from a large-diameter pipe cutting configuration to a small-diameter pipe cutting configuration. An arm carrying a pressure roller assembly is pivoted to a body part carrying a rotatable cutter. The pressure roller assembly is pivotable from one side of the arm to the other for accommodating different pipe sizes. The body is adjustably mounted in a support member carrying a diameter adjusting screw, a depth adjusting set screw and a handle.
