A hand tool to render pipes and tubes bendable |
摘要 |
The tool comprises an adjustable clamp 4 hinged to a body 5 which forms a support for the tube. A hardened wheel 2 or blade 7 is mounted askew within the clamp 4 so that rotation of the tool while clamped to the tube impresses a helical track in the tube. A screw adjustment 3 sets the depth of the hardened blade or wheel which is removable for replacement. <IMAGE> |
