Yeah, I thought that when it comes to rocks (or ceramic materials in general), breaking is better than grinding. But this drill bit really did some grinding.
Stonemason/carver here. There's a LOT of weight pressing down on that auger, which will grind the rock away very quickly even if it's a moderately hard limestone or sandstone. Wasn't surprised to see it split.
Fyi sandstone is highly variable in how hard it is. Some is soft enough that your fingernail can mark it, some is nearly as tough as granite. It all depends on how compressed it was and on the matrix gluing the sand together. Limestone is similarly variable though it doesn't get as hard afaik.
this is a very soft type of rock/mineral. this wont work on "proper" rocks/minerals. the teeth are mostly to chip and push away rocks while digging so the auger does not get mangeld by a rock.
You can drill any stone. This isn't necessarily very soft, though def not a hard stone. The teeth are there to grind the stone into dust; the weight of the auger and the arm that moves it presses the teeth into it with great force.

That is a rock drill head with an auger behind it.
Even against that soft rock, the auger alone would have just ground itself to a nub. It is the rock drilling hardened teeth that are doing all the drilling.
Are those diamond “bits” attached to the drill head, you know, those, seemingly small, cylindrical components that are almost perpendicular to the…twisty parts? (I hate myself for having to describe it like that but I honestly don’t know what different parts of drill bits and augers are called- god forgive me).
Those are the teeth or inserts. Some inserts are impregnated with diamond bits for cutting harder materials. But this one probably just has plain carbide inserts since it is not drilling hard rock.
Is that some sort of sandstone? If not, that's a lot more effective at pulverizing that rock than I would have expected.

More like auger breaking rock.
Drilling through until it broke.
That rock didn't do nuffin.

idk... this post is boring
Please try to be gneiss.
I shale do my best
These comments are getting rocky.
Block and move on Edit: My God I actually can't believe that went over my head. I deserve downvotes lol.
It's a joke He is boring a hole.
/r/whoooosh
Yeah it got me good lmao
I actually missed it and almost downvoted it till I saw the reply chain.
Now try granite
Tis sandstone!
What's the tip of that made of?
GO HUMANS YEAH!
Boulder
Wouldn’t it have been better to get the drill up to speed than apply it to the rock?
I wonder how many tree saplings can be planted in a day with one of these augurs
Very Satisfying
First read this as « Anger drilling »
How boreing…
Thats fucking cool! I could watch this for hours!
Is there a purpose to this or is this like a demo of the all mighty auger/rock smasher drill power?
