The Earth's crust is not hard to drill into there's just a lot of it.
The crust is just the rock ground- digging a hole in the ground is breaking the crust. The reason we have not penetrated it is that it is 5 miles thick at its thinnest point. The deeper you go, the hotter it gets, and beyond a certain depth, it would become too hot for any drills to work properly.
The Earth's crust is hard to drill into because it is composed of solid rock layers that can be very thick and dense. Additionally, the crust can contain various types of rocks with different hardness and composition, making drilling difficult and requiring specialized equipment. The pressure and temperature increase as you go deeper into the Earth, further complicating the drilling process.
Diamond hard.
Geologists use drill bits with diamonds because diamonds are one of the hardest materials on Earth, making them effective for cutting through hard rock and sediment. The diamond-covered bits can withstand the high pressures and temperatures encountered while drilling into Earth's crust, allowing geologists to access subsurface samples for study and analysis.

Geologists use drill bits covered with small diamonds because diamonds are the hardest natural substance and can effectively drill through hard rocks in the Earth's crust. The diamonds on the drill bits help to create a clean and precise hole without getting worn out easily compared to other materials. This allows geologists to obtain core samples for studying the composition and structure of the Earth's crust.
It is generally easier to drill through continental crust than oceanic crust. Oceanic crust tends to be thinner, denser, and harder than continental crust, making it more challenging to drill through. Continental crust is thicker and less dense, with more varied geological features and compositions that can be easier to penetrate.

There have been several attempts to drill all the way through the Earth's crust and into the mantle, but these have not yet succeeded.
Diamond hard.
Well, diamonds are hard minerals, and if they are used in a drill, it could help with the power given and make the course, and power of the drill increase. Diamonds are minerals and they are found in South Africa. You dig them up and they are contained in a rock called "kimberlite" after that you give the shape, size and polish the diamond. They may use them for other things, not only jewelry. They are also used in: Telecommunication, rock drill bit, mine shack..... This information is true, i will post more soon! ;)
Because they have to get through the minerals and rocks in the earths crust.
Gneiss is a part of the earths lower crust. No matter where you drill you will eventually uncover gneiss.
Because the Earths crust is extremely hard to drill into, also interior earth exploration does not yield anywhere near the advantages as that of space exploration.
Earth's crust is very hard because it is made of rock. If it wasn't hard you would sink down into the Earth's core.

The crust is the outermost layer of the Earth, the shell made up of hard oceanic and continental rocks.
The Earths crust is approximately 650 km deep.
The lithosphere is composed of the hard and brittle outer shell of the Earth consisting of the crust and the uppermost mantle.
