My impression is Quaise's maser (?) drill thingie would be used for granite. Which is increasingly a challenge for geothermal (going deeper, longer).

Can types of drill bits (heads?) be swapped out? So use the super diamond bit to get started, then switch to Quaise's maser once you reach granite.

Just guessing. Am noob. Am just trying to follow along.

eg Most recent Volts podcast episode: An update on advanced geothermal w/ Tim Latimer of Fervo Energy.

You'd need to trip out of hole for it, but that isn't really a problem. I know the video acts like tripping is the end of the world, but it's a standard day to day practice offshore. Everytime something breaks or dies down hole, or you finish a section of hole you need to case, you have to trip.

So yes, you could swap the two out. But we already have bits that are good at drilling hard rock (granites, etc) they're called tricone bits. They more so crush the rock than cut it. And they look badass.
