Arc-Fit
How it Works: The Arc-Fit method is a simple and dependable way to create notches in pipe or tubing, slots and many other
types of end notches.
The tooling consists of Housings and interchangeable Punch & Die Assemblies. Each different
tube or pipe size or notch configuration requires a different Assembly. Many different Assemblies
will fit the same Housing, up to the maximum capacities listed in the charts below. The final
component is a press, to provide power. Our Arc-Fit tooling can fit many ironworkers, punch presses,
or even press brakes. We offer presses, either manual, pneumatic, or hydraulic, to power your Arc-Fit tooling.
Your tube or pipe is slid, horizontally, over the Tube Rest, onto the Punch. The punch fits the ID of
your material. The Punch Holder functions as an end-stop.
The Press pushes the Punch & Punch Holder downward, through the bottom wall of your material. The
Tube Rest is also a cutting edge, supporting the underside of your material, preventing deformation.
In most cases (round pipe fitting round pipe, for example), the material is rotated 180° and a second
notch made. Simple scribe lines on the Punch Holder help line up the material for the second notch.
Arc-Fit tools are designed for many years of use. Our Punches and Tube Rests are designed to be
sharpenable. We have made thousands of custom Arc-Fit assemblies to suit specific applications.
