<p>A mechanical pipe cutting device comprising of a shaft body with a tapered spring loaded internal drive shaft, with interchangeable heads of varying sizes. The sole purpose of the tool is to cut pipes of different sizes from within. Each head has multiple spring loaded blades that are forced outwards by downward pressure. The shaft body has an adjustable depth guide so that the downward pressure of the operator forces the spring loaded tapered drive shaft against the pistons holding the spring loaded cutters. This is all driven by some form of rotational motive power. As downward pressure is applied the cutters are forced into the surrounding pipe. On cutting through the downward pressure is released, the blades retract. The tool is ready to be extracted from the inside of the pipe</p> |
