Waterjet cutting uses water to propel a powder which acts as an abrasive, like an infinite stream of sandpaper. I don't think water by itself will achieve much.

- climb_stealth 5y agoHuh, thanks for mentioning this! I always thought it was just water with enough pressure. It looks like pressure cutting with pure water exists but it is limited to softer materials. This page [0] has a fair bit of detail on it all.

- daenz 5y agoSounds like pressure washing vs sand blasting. Only difference between the two (aside from drastically different effect) is sand blasting has an intake tube to suck sand into the water jet.

- nullc 5y agoWaterjeting without abrasive is a thing, it's used for soft materials like rubber... and there are some companies marking higher pressure approaches for metal (though usually with tiny amounts of abrasive rather than none at all).
