Pipe beveling attachment for a power tool

A pipe beveling attachment for a power tool having a rotary cutter, comprising:

• a base member;
• support means on the base member for mounting a power tool thereto with the rotary cutter facing the base member;
• an opening formed through the base member for receiving the rotary cutter of the power tool;
• a freely rotatable core engaging roller;
• core roller adjusting means on the base member mounting the core engaging roller to the base plate for selective movement of the core engaging roller in relation to the opening;
• outside roller means to each side of said core engaging roller for engaging and rolling over the outside surface of a pipe end whose inner surface is engaged by the core engaging roller to thereby guide the cutting tool in an arcuate path relative to the axis of the pipe end;
• said support means being movably adjustable relative to said outer roller means.

A pipe beveling attachment for a power tool having a rotary cutter, said attachment comprising:

• a planar base member having oppositely facing front and back surfaces;
• an elongated slotted opening formed through the base member;
• a bracket movably mounted to the base member for motion parallel to the length of the slot, said bracket being extended outward from the back surface of the base member;
• means on said bracket adapted to adjustably support a power tool in a position wherein its rotary cutter extends forwardly through said opening;
• a core engaging roller;
• means on said bracket mounting said core engaging roller for rotation about a roller axis perpendicular to the front base member surface and protruding forwardly therefrom adjacent the intended rotary cutter position;
• and a pair of outer rollers journalled by the base member to each side of the core engaging roller about axes parallel to the core engaging roller axis, said outer rollers also protruding outward from the front base member surface.
