A electrical power tool with a circular saw blade attached to a drive shaft of an electric motor. The power tool includes a pipe engaging bracket. The pipe-engaging bracket includes a “L” shaped bracket arm having a first arm member and a second arm member. The first arm member is attached to a side of the housing. The second arm member is at right angles to the first arm member. The second arm member includes a pair of spaced apart guide pin holes for receiving a center portion of a pair of guide pins therethrough. An upper portion of the guide pins is received through a pair of coil springs. The coil springs are held on the upper portion of the guide pins using spring stops. A lower portion of the guide pins includes ends attached to a guide arm. The guide arm is parallel to the second arm member. The guide arm includes a pair of spaced apart guide fingers with pipe grooves therein. The guide fingers are disposed on opposite sides of the saw blade. The pipe grooves are adapted for receiving a portion of a pipe to be cut by the saw blade.
