A pipe cutting apparatus having a frame and first and second pipe support arms. The pipe support arms are pivotally attached to the frame. First and second pipe support members on the first and second arms together with a third pipe support member securely grip the pipe at substantially equally circumferentially spaced locations. A camming member is used to place the first and second pipe support arms in predefined locations for holding differently sized pipes. An linkage assembly causes the third pipe support member to biasingly engage the pipe. A two-part tool shield is provided together with a depth adjusting assembly for facilitating the cutting and beveling of the pipe. A power transmission assembly transfers power from a motor on the frame to a tool located on a pivoting arm. The frame may be manufactured using an adhesive filler material for enhancing the rigidity, strength and accuracy of the components.

What is claimed is: 1. An apparatus for cutting a substantially cylindrical pipe, said apparatus comprising: a structural frame for supporting the pipe; a tool arm pivotally mounted to said frame; a cutting assembly mounted on said tool arm, said cutting assembly including a shaft having adjacently mounted thereon at least one beveling blade and a cutting blade; said shaft being rotatably supported on said tool arm; and a depth adjusting assembly disposed on said tool arm including a camming member and at least one positioning member, said positioning member adapted to engage the pipe and thereby define a distance between the pipe and said cutting assembly shaft, said camming member engaged with said positioning member wherein adjustment of said camming member selectively adjusts said positioning member relative to said cutting assembly shaft and the tool arm and thereby adjusts the distance between the pipe and said cutting assembly shaft.
