Will the tool notch materials like 4130 Chrome-Moly steel, stainless steel, titanium?
Yes. Our tool will handle metal pipe or tubing up to 2″ O.D. How well the notcher works on these materials is a function of the hole saws used (not included), not the tool itself. Difficult-to-cut materials like those above will shorten saw life somewhat, but replacement saws are inexpensive. We sell the Lenox brand hole saws as they have given the best results, but any good bi-metal hole saw will work. You must apply lubrication (preferably cutting oil) on all materials, especially those listed above to maintain optimum performance.
