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.
Because we can not drill through the earths crust
oceanic crust
the diamonds are the strongest natural material on earth. these drills can drill through anything
The Chikyu research vessel
Because they have to get through the minerals and rocks in the earths crust.
no
Because oil is in the crust, scientists never drilled to the mantle so far because it is too deep for them.
Depending on the type of drill BIT, it may drill through almost anything.
No they arent able to because earths inner core is to hot for them to drill!
Diamond hard.
If you drill, you will go through the Earth's crust, and for approx 1,800 miles of solid material (called the mantle). After that you will enter the core, which is made of iron and nickel, but the temperature goes up to 3700º Celcius and therefore is in liquid form. So, to answer your question, no, you cannot drill into the core of the earth.
because the earths core is too hot. all materal would burn
