The Model WFN4 power pipe and tubing notcher uses a power-driven gearbox to produce 90-degree notches in pipe or tubing for weld fit-up saddles. Available from Heck Industries, the machine will notch diameters ranging from ¼" to 2 3/8". It is capable of notching at 38 strokes per minute for production jobs. According to the company, the portable machine is easy to mount to any surface or bench vise, and no setup is required. Users simply insert the pipe into the correct size hole and pull the handle.
