ABSTRACT:
A tool is provided for notching an end of a pipe. A punch is provided with a first cutting edge opposite a second cutting edge. The punch is coupled to a punch holder which is configured to move vertically relative to a collar supported upon a base. A pipe support provides a preferred form of die to hold the pipe adjacent the punch. The pipe support includes a first edge, second edge, third edge and fourth edge which can be selectively presented for supporting the end of the pipe adjacent the punch. The first cutting edge and second cutting edge of the punch can be selectively provided for cutting the notch in the pipe. The punch and pipe support are preferably both re-orientable to select various different edges for supporting and cutting the pipe.
