The Arc-Fit method is a low-cost way of creating accurate notches in tube or pipe ends. The tube is slid onto the tube rest, over the punch. As the punch and punch holder are depressed, the punch notches the bottom wall of the tube. The tube is rotated 180 degrees and the first notch, now on the top of the tube, is visually aligned with the scribe lines on the punch holder. The 2nd notch is made and the tube is ready for welding or brazing. These spring-loaded tools may be powered by most press brakes, iron workers, punch presses, or Hand or Hydraulic Presses. Although most popular for 90 degrees T-Joint notches, custom assemblies may be ordered for custom shaped slots, notches with drain-holes and more.
