摘要

The machine for forming perpendicular holes in tubing has a V-shaped base to receive the tube (5) and a saddle (2) or metal rod with wing nuts (3) to clamp the tube onto the base. An interchangeable diameter guide bore (4) is screwed onto the upper part of the base to guide a drill bit. A return finger indexes a zero angle on the base.
