Abstract
The present invention is a cast iron pipe cutter. The cast iron pipe cutter includes a movable upper cutting tool and a rigid lower cutting tool. The upper cutting tool and lower cutting tool includes multiple cutting disc spaced an arc length apart. As the upper cutting tool is advanced downward by a hydraulic press, the cutting discs apply increasing pressure to the outer surface of a cast iron pipe until each cutting discs in the upper cutting tool and the lower cutting tool creates a fracture in the cast iron pipe. The multiple fractures created by the cutting discs amalgamate into a single fracture and the cast iron pipe is cut almost instantaneously.

A pipe cutter compromising:
- a movable upper cutting tool positioned above a stationary lower cutting tool;
- and
- a hydraulic press for delivering a hydraulic fluid under pressure to move the movable upper cutting tool.
A pipe cutter compromising:
- a movable upper cutting tool positioned above a stationary lower cutting tool;
- a hydraulic press for delivering a hydraulic fluid under pressure to move the movable upper cutting tool toward the stationary lower cutting tool;
- a plurality of cutting discs connected to the moveable upper cutting tool at an upper pressure plate and to the lower cutting tool at a lower pressure plate;
- wherein the moveable upper cutting tool and the stationary lower cutting tool are removable to facilitate a selection of the moveable upper cutting tools and stationary lower cutting tool with an optimum number of the plurality of cutting discs needed to cut a specific diameter of a cast iron pipe.
