Using a 60,000 PSI Waterjet to Try and Cut Through the HARDEST Materials

When it comes to spending time in the garage, there are all sorts of different tools to get different jobs done. Naturally, there is a spectrum from simple to complex and this time, we take a look at a unit that’s on the more complex side of things.

For those who regularly have to make precise cuts through difficult objects, perhaps something like a waterjet could come in handy. The purpose of such a tool is to be able to use water to cut through a variety of different materials. It almost seems like this thing is unstoppable as the pressure is turned up and the waterjet makes its way through a variety of hard surfaces.

This time, we check in with a couple of the hardest materials that this particular waterjet channel has decided to put up against the tool. In order to test things out, the crew brings along Obsidian, Quartz, Topaz, and a ceramic composite, all with the aim of stopping the waterjet in its tracks and seeing just how far it can be pushed. These are some of the hardest materials on the Mohs Scale of Mineral Hardness which ranges from soft materials like Talc all the way up to the hardest materials like Diamonds.

By following along with the video below from Waterjet Channel, we just see how far a waterjet can make it.

Will they still be able to slice a smooth cut through all of these objects? Could the waterjet make its way all the way through materials that are as hard as diamonds? Certainly, there has to be a limit to what this thing can do. In any case, it’s super fun to watch as the water just pushes the limits to see which materials will stand up to the test and which simply aren’t going to be able to deal with 60,000 psi.
